The Role of Interdisciplinarity in Modern Research: A Guide for Scientists

Interdisciplinary research integrates knowledge, methods, and perspectives from two or more disciplines to address problems that exceed the capacity of any single field. For scientists in the life sciences, public health, conservation, and related fields, this approach has moved from an academic ideal to a practical necessity. Complex challenges such as infectious disease outbreaks, ecosystem degradation, and chronic disease prevention involve biological, social, economic, and infrastructural factors that no single discipline can fully capture. This guide explains the benefits and challenges of interdisciplinary work, provides a framework for designing such studies, and offers practical steps for integrating methods and collaborating across fields.

At a Glance: Interdisciplinary Research Considerations

Why Interdisciplinary Research Matters

The scale and complexity of contemporary challenges demands interdisciplinarity in research and pluralism in practice. A strong natural science hegemony has often framed our understanding of the dynamics of nature and society, yet both the drivers of sustainability challenges and the agents with the capacity to address them are social and require insights from the social sciences. This observation comes from analysis of the Lund University Centre of Excellence for Integration of the Social and Natural Dimensions of Sustainability, which identified that synthetic integrated knowledge is more likely to be produced when researchers employ retroductive logic and adhere to methodological pluralism. The institutional setting matters for supporting such research, both in terms of finance and administration and in providing a conducive intellectual environment.

Interdisciplinary research in physics, chemistry, and biology is central to understanding biological processes. The integration of these disciplines allows researchers to examine biological questions at multiple scales, from molecular interactions to organism-level behavior. Similarly, interdisciplinary research in public health addresses the why and the how of health outcomes, recognizing that health is determined by factors ranging from individual biology to community-level social conditions.

The COVID-19 pandemic illustrated the practical urgency of interdisciplinary methods. More than 130,000 peer-reviewed studies were published within one year after COVID-19 emerged in many countries. This large and rapidly growing field overwhelmed the synthesizing abilities of both researchers and policy-makers. A review of this literature identified nine interrelated problems and research needs, including nation-wide geo-referenced epidemiological data collection systems open to and monitored by the public, metrics meant to detect non-symptomatic cases such as test positivity, cost-benefit oriented methods that demonstrate they detect silent viral spreaders even with limited testing, new personalized tests that inform on biological functions and disease correlates, factors that influence vaccine effectiveness, and economic predictions that consider the long-term consequences likely to follow epidemics. These findings demonstrate that effective pandemic response requires coordinated work across epidemiology, economics, immunology, and policy analysis.

Core Principles of Interdisciplinary Research

Ontology, Epistemology, and Philosophical Perspective

Natural scientists who engage in social science but are unfamiliar with its philosophical principles and assumptions can misinterpret results. The three fundamental elements of research are ontology, which concerns what exists in the human world that researchers can acquire knowledge about, epistemology, which concerns how knowledge is created, and philosophical perspective, which is the philosophical orientation of the researcher that guides action. Many elements of this framework also apply to the natural sciences.

Understanding these elements helps researchers determine how the ontological position of a researcher can influence the nature of the research, how the epistemological position can be used to support the legitimacy of different types of knowledge, and how philosophical perspective can shape the researcher's choice of methods and affect interpretation, communication, and application of results. This understanding supports and promotes the effective integration of the natural and social sciences to generate more insightful and relevant research outcomes.

Quantitative and Qualitative Method Reconciliation

While natural and social scientists may share a general understanding of how science is conducted, disciplinary differences in methodologies quickly emerge during interdisciplinary research efforts. Quantitative and qualitative approaches have different philosophical underpinnings. A pragmatic, realistic approach may allow natural and social scientists to work together productively. Realism assumes that there is a reality that exists independently of our perceptions, and the work of scientists is to explore the mechanisms by which actions cause meaningful outcomes and the conditions under which the mechanisms can act.

The task of interdisciplinary researchers is to use the insights of their disciplines in the context of the problem to co-produce an explanation for the variables of interest. Research on qualities necessary for successful interdisciplinary researchers has identified specific skills and dispositions, and funding agencies and academia have increased capacities for interdisciplinary research through targeted programs.

Methodological Pluralism

Analysis of interdisciplinary research programs suggests that synthetic integrated knowledge required to analyze and address complex sustainability challenges is more likely to be produced if researchers employ retroductive logic and adhere to the principles of methodological pluralism. Retroduction involves identifying the underlying mechanisms that produce observed phenomena, instead of simply describing patterns or testing predictions. Methodological pluralism means using multiple methods from different disciplinary traditions to examine a problem from different angles, instead of forcing all questions into a single methodological framework.

Designing an Interdisciplinary Research Project

Step 1: Define the Problem Jointly

The first step in interdisciplinary research is to develop a shared problem definition. This requires that team members from different disciplines articulate how they see the problem, what questions they consider important, and what outcomes would count as progress. This step often takes longer than researchers expect because disciplinary training shapes what problems seem worth studying and what evidence is considered convincing.

For example, in ecosystem-based management, integration of natural and social sciences to inform conservation efforts has been difficult. A study of 63 scientists and practitioners involved in marine management in Mexico's Gulf of California, the central California coast, and the western Pacific found that many traditional challenges linked with interdisciplinary research were present in the projects studied. Contextual elements affected how mandates to include social science were interpreted and implemented. A common challenge is that conservation organizations are often dominated by natural scientists, but for some projects it was easier to address this imbalance than for others. Management and institutional histories that came before ecosystem-based management in specific cases were important features of local context. Because challenges differed among cases, resolving challenges to interdisciplinary research should be context specific.

Step 2: Identify the Disciplinary Contributions

Once the problem is defined, the team should identify which disciplines have relevant knowledge, methods, or perspectives to contribute. This involves mapping the problem to potential disciplinary inputs and determining which combinations are necessary to address the problem adequately.

For healthy longevity, a comprehensive interdisciplinary approach to prevention of preventable mortality and prolonging healthy life of the elderly is based on analysis of medical, social, economic, and infrastructural determinants of longevity. Key determinants include level of education, possibility of annual dispensarization, access to infrastructure of locality and region, and social services. This analysis supports the transition from biomedical strategies to comprehensive preventive ones based on application of medical and educational technologies.

Step 3: Select and Integrate Methods

Method selection in interdisciplinary research requires attention to how methods from different traditions can be combined. The choice of methods should follow from the problem definition and the types of knowledge needed, not from disciplinary habit.

For example, a consensus definition for advance care planning was developed through a Delphi panel of multidisciplinary, international experts consisting of 52 clinicians, researchers, and policy leaders from four countries and a patient or surrogate advisory committee. The panel conducted 10 rounds using a modified Delphi method and qualitatively analyzed panelists' input. Panelists identified several tensions concerning advance care planning concepts, such as whether the definition should focus on conversations versus written advance directives, patients' values versus treatment preferences, current shared decision making versus future medical decisions, and who should be included in the process. The panel achieved a final consensus one-sentence definition and accompanying goals statement. This example shows how structured methods from one tradition, in this case Delphi consensus methods, can be adapted to integrate perspectives from multiple disciplines.

Step 4: Plan for Integration

Integration is the process of combining disciplinary insights into a coherent whole. This is different from simply placing disciplinary findings side by side. Integration requires that researchers actively work to understand how findings from different disciplines relate to each other, where they conflict, and what new insights emerge from their combination.

The COVID-19 literature review provides an example of an interdisciplinary method on methods. The first review started in biology and ended in policy, with policy chosen as a destination because it is the setting where cognitive integration must occur. The second review followed the opposite path, beginning with stated policies on COVID-19 and then identifying their assumptions and disciplinary relationships. The purpose of this approach was to yield a relational and explanatory view of the field, one strategy likely to be incomplete but usable when large bodies of literature need to be rapidly summarized.

Step 5: Build the Team and Institutional Support

Successful interdisciplinary research requires team members who have specific qualities and an institutional environment that supports collaboration. Research on qualities necessary for successful interdisciplinary researchers has identified traits such as openness to other perspectives, willingness to learn new methods, and ability to communicate across disciplinary boundaries.

Institutional settings matter for supporting interdisciplinary research, both in terms of finance and administration and in providing a conducive intellectual environment. The LUCID analysis stressed the importance of institutional settings in supporting such research. Building collaborative cultures through interdisciplinary research has been demonstrated in examples from the University of British Columbia, Canada, where institutional structures were developed to support cross-disciplinary collaboration.

Practical Workflow for Interdisciplinary Collaboration

Establish Communication Protocols

Disciplinary jargon is a practical barrier to collaboration. Teams should establish communication protocols that include definitions of key terms, expectations for explaining disciplinary concepts, and mechanisms for checking understanding. This may include a shared glossary, regular team meetings where members explain their work in plain language, and written summaries that translate technical findings for the team.

Create Integration Checkpoints

Integration should not be left to the end of a project. Teams should build integration checkpoints into the project timeline where members explicitly discuss how their findings relate to each other. These checkpoints might occur at the design stage, after preliminary data collection, and before final analysis.

Document Decisions and Rationale

Interdisciplinary projects involve many decisions about problem framing, method selection, and interpretation. Teams should document these decisions and their rationale. This documentation serves multiple purposes: it helps new team members understand the project's logic, it provides material for reporting to funders, and it supports the writing of methods sections that explain the interdisciplinary approach.

Use Available Tools and Standards

Several tools and standards can support interdisciplinary research. The Experimental Design Assistant from the NC3Rs provides guidance for designing experiments that are robust and reliable. The EQUATOR Network provides reporting guidelines for health research that help ensure studies are reported completely and transparently. The Research Data Framework from the National Institute of Standards and Technology addresses data management across the research lifecycle. The National Center for Biotechnology Information provides literature resources including PubMed, which researchers can use to search across disciplinary literatures.

Options and Tradeoffs in Interdisciplinary Research

Breadth versus Depth

Interdisciplinary research requires a tradeoff between breadth and depth. Researchers must have enough depth in their home discipline to contribute meaningfully, while also developing enough breadth to understand and integrate insights from other disciplines. This tradeoff has implications for career development, as interdisciplinary researchers may be perceived as less expert in any single field.

Integration versus Aggregation

Teams can approach interdisciplinary work in different ways. Aggregation involves collecting findings from different disciplines and presenting them together without substantial integration. Integration involves actively working to combine insights into a new understanding that transcends the individual disciplinary contributions. Integration is more difficult but produces more valuable outcomes.

Problem-Driven versus Discipline-Driven Research

Interdisciplinary research can be problem-driven, starting with a real-world problem and bringing in whatever disciplines are needed, or discipline-driven, starting with questions that emerge from within a discipline and reaching out to other fields for methods or perspectives. Both approaches have value, but they have different implications for how the research is framed and how collaborators are engaged.

Qualitative and Quantitative Combinations

Reconciling qualitative and quantitative methods is a specific challenge in interdisciplinary research. Qualitative methods from the social sciences and humanities can provide depth of understanding, context, and attention to meaning. Quantitative methods from the natural and social sciences can provide measurement, generalizability, and hypothesis testing. Combining these approaches requires attention to their different philosophical underpinnings and standards of evidence.

Observations and Measurements in Interdisciplinary Research

What to Measure

The choice of measurements in interdisciplinary research follows from the problem definition and the types of knowledge needed. In public health research, measurements might include biological indicators, behavioral measures, social determinants, and policy outcomes. In conservation research, measurements might include ecological indicators, economic valuations, and social attitudes.

How to Record Observations

Interdisciplinary research requires attention to how observations are recorded across different disciplinary traditions. Natural scientists typically record quantitative measurements with attention to precision and reproducibility. Social scientists may record qualitative observations such as interview transcripts, field notes, or documents. Teams need to agree on how these different types of observations will be documented, stored, and made accessible to all team members.

Data Management

The Research Data Framework from the National Institute of Standards and Technology addresses the full research data lifecycle, including planning, collection, processing, analysis, preservation, and sharing. Interdisciplinary projects benefit from explicit attention to data management because different disciplines have different conventions for data formats, metadata, and sharing.

Records and Documentation

Project Records

Interdisciplinary projects should maintain records that document the research process as well as the findings. These records might include meeting minutes, decision logs, method notes, and correspondence. Such records are valuable for understanding how the project developed, for reporting to funders, and for training new team members.

Methods Documentation

Methods sections in interdisciplinary publications need to explain also what was done but also why the interdisciplinary approach was necessary and how the methods from different disciplines were integrated. This documentation is important for readers who may be unfamiliar with methods from other disciplines.

Data and Code Sharing

Many funders and journals now require data and code sharing. Interdisciplinary projects face particular challenges in this area because different disciplines have different conventions for data sharing and different types of data require different sharing approaches. Qualitative data may raise confidentiality concerns that quantitative data do not, and biological data may have ethical or regulatory constraints.

Quality and Welfare Controls

Research Quality

Quality in interdisciplinary research requires attention to the standards of each contributing discipline as well as to the quality of the integration. Teams should establish quality criteria at the outset and revisit them as the project develops. The EQUATOR Network provides reporting guidelines that help ensure health research is reported completely and transparently, which supports quality assessment by readers and reviewers.

Ethical Considerations

Interdisciplinary research raises ethical considerations that may not be fully addressed by the ethics frameworks of any single discipline. Research involving human participants requires attention to consent, confidentiality, and potential harms. Research involving animals requires attention to welfare. Research involving communities requires attention to engagement, benefit sharing, and respect for local knowledge.

Welfare Considerations

For research involving animals, the Experimental Design Assistant from the NC3Rs supports the design of experiments that are robust and reliable while minimizing animal use and suffering. This tool helps researchers think through experimental design decisions that affect both scientific quality and animal welfare.

Common Failure Patterns in Interdisciplinary Research

Disciplinary Dominance

A common failure pattern is when one discipline dominates the research process, framing the problem, selecting methods, and interpreting results in ways that marginalize other disciplinary perspectives. This pattern is particularly common when natural science disciplines dominate conservation or health research, as noted in the ecosystem-based management study where conservation organizations were often dominated by natural scientists.

Tokenism

Tokenism occurs when researchers from other disciplines are included on a team but their contributions are not genuinely integrated into the research. This can happen when social scientists are added to a natural science project to satisfy funder requirements but their methods and findings are not given equal weight.

Premature Method Selection

Teams sometimes select methods before fully defining the problem or understanding what types of knowledge are needed. This can happen when researchers default to the methods of their home discipline or when teams adopt methods because they are familiar instead of because they are appropriate.

Communication Breakdown

Communication breakdowns occur when team members do not invest in developing shared language and understanding. This can lead to misunderstandings about what different disciplines can contribute, frustration with perceived lack of rigor in other disciplines, and failure to integrate findings.

Inadequate Integration

Some interdisciplinary projects produce findings from different disciplines but fail to integrate them into a coherent whole. This can happen when integration is left to the end of the project, when no one has responsibility for integration, or when team members do not have the skills or time to engage deeply with other disciplinary perspectives.

Limitations of Interdisciplinary Research

Time and Resource Demands

Interdisciplinary research takes more time and resources than single-discipline research. Teams must invest in developing shared understanding, learning about other disciplines, and managing the logistics of collaboration. These costs are real and should be planned for.

Career and Institutional Barriers

Interdisciplinary researchers may face career barriers because academic evaluation systems often reward disciplinary specialization. Research on interdisciplinary academic evaluation methods from the perspective of scientometrics has examined how evaluation systems can be adapted to recognize interdisciplinary contributions. Peer review of interdisciplinary research presents particular challenges, as reviewers may be unfamiliar with parts of the work or biased against interdisciplinary approaches.

Epistemological Differences

Differences in philosophical assumptions about what counts as knowledge and how it should be produced can create fundamental challenges for interdisciplinary teams. These differences are not simply matters of method but reflect different understandings of the nature of reality and knowledge. Teams that do not address these differences explicitly may find that they talk past each other.

Context Specificity

Challenges to interdisciplinary research are context specific. The ecosystem-based management study found that challenges differed among cases and that resolving them required attention to local context. This means that approaches that work in one setting may not transfer directly to another.

Safety and Regulatory Context

Research Governance

Interdisciplinary research is subject to the governance frameworks of the institutions and jurisdictions where it is conducted. Researchers should be aware of the requirements that apply to their work, including those related to human participants, animal welfare, data protection, and research integrity.

Professional Escalation Criteria

Researchers should know when to escalate concerns to appropriate authorities. This may include concerns about research misconduct, ethical violations, safety issues, or regulatory noncompliance. Teams should establish clear lines of responsibility and communication for addressing concerns.

Jurisdiction-Specific Requirements

Research requirements vary by jurisdiction and by field. Researchers should identify the specific requirements that apply to their work and ensure that their practices comply. This may involve consulting institutional research offices, ethics committees, or regulatory agencies.

Professional Escalation Criteria

Researchers should escalate concerns to appropriate authorities when they encounter situations that exceed their expertise or authority. Specific situations that warrant escalation include:

• Suspected research misconduct, including fabrication, falsification, or plagiarism
• Ethical concerns that are not adequately addressed by the team's current approach
• Safety concerns related to research activities
• Regulatory noncompliance or uncertainty about regulatory requirements
• Conflicts within the team that cannot be resolved through normal communication processes
• Findings that have implications beyond the research team's capacity to address

Frequently Asked Questions

What is the difference between multidisciplinary, interdisciplinary, and transdisciplinary research?

Multidisciplinary research involves researchers from different disciplines working on a common problem but maintaining their disciplinary perspectives and methods. Interdisciplinary research involves integrating knowledge and methods from different disciplines to create a new understanding that transcends individual disciplinary contributions. Transdisciplinary research goes further by involving non-academic stakeholders, such as community members or practitioners, in the research process. The distinctions are not always sharp in practice, but they reflect different levels of integration and different relationships between academic and non-academic knowledge.

How do I know if my research question requires an interdisciplinary approach?

A research question requires an interdisciplinary approach when it involves factors that span multiple disciplinary domains, when the problem cannot be adequately addressed using the methods of a single discipline, or when the problem is defined by real-world concerns instead of by disciplinary questions. For example, a question about how to reduce preventable mortality in elderly populations requires attention to medical, social, economic, and infrastructural factors, as identified in the analysis of healthy longevity determinants. If your question involves such multiple domains, an interdisciplinary approach is likely necessary.

What are the main challenges of interdisciplinary research?

The main challenges include reconciling different philosophical assumptions about knowledge, integrating quantitative and qualitative methods, overcoming disciplinary jargon and communication barriers, addressing power imbalances between disciplines, navigating peer review and publication systems that are organized by discipline, and securing funding and institutional support. These challenges are well documented in studies of interdisciplinary research in ecosystem-based management and other fields.

How do I integrate qualitative and quantitative methods in my research?

Integration of qualitative and quantitative methods requires attention to the philosophical underpinnings of each approach. A pragmatic, realistic approach allows researchers to work together productively by focusing on the mechanisms by which actions cause outcomes and the conditions under which those mechanisms operate. The task is to use the insights of each discipline in the context of the problem to co-produce an explanation for the variables of interest. This requires explicit attention to how different types of data relate to each other and what each type of data can and cannot tell you.

How do I find collaborators from other disciplines?

Finding collaborators requires identifying researchers whose expertise is relevant to your problem and who are open to interdisciplinary work. Strategies include attending conferences outside your home discipline, using literature searches to identify researchers working on related problems from different angles, and seeking out institutional programs that support interdisciplinary collaboration. Building collaborative cultures through interdisciplinary research has been demonstrated in institutional examples such as those at the University of British Columbia.

How do I publish interdisciplinary research?

Publishing interdisciplinary research requires identifying journals that are open to interdisciplinary work or that have specific interdisciplinary scope. Researchers should be prepared for peer review challenges, as reviewers may be unfamiliar with parts of the work or may apply mono-disciplinary standards. The peer review of interdisciplinary research has been studied, with findings that authors of interdisciplinary papers report experiencing disadvantage in peer review practices, including perceived bias and assignment of unsuitable reviewers. Researchers should also be prepared to explain their interdisciplinary approach clearly in the methods section.

What skills do I need for interdisciplinary research?

Successful interdisciplinary researchers need openness to other perspectives, willingness to learn new methods, ability to communicate across disciplinary boundaries, and capacity to engage with different philosophical assumptions about knowledge. Research on qualities necessary for successful interdisciplinary researchers has identified these and other traits. These skills can be developed through training, practice, and engagement with researchers from other disciplines.

How do I evaluate the quality of interdisciplinary research?

Evaluating interdisciplinary research requires attention to the quality of the disciplinary contributions and to the quality of the integration. Reviewers and evaluators should assess whether the methods from each discipline are applied appropriately, whether the integration is genuine instead of superficial, and whether the integrated findings provide insights that could not have been achieved through single-discipline research. Research on interdisciplinary academic evaluation methods from the perspective of scientometrics has examined how evaluation systems can be adapted to recognize interdisciplinary contributions.
