How to Land a Bioinformatics Internship
By Dr. Zubair Khalid, DVM, MS, PhD ·

Quick Answer
- Find bioinformatics internships through official federal training portals, university career services, and professional society job boards that list structured research programs.
- Tailor each application to the specific lab or program by showing relevant coursework, coding projects, and biological domain knowledge instead of sending identical materials.
- Treat the internship as a professional apprenticeship where you document methods, ask for feedback, and build a portfolio of reproducible work, beyond a line on your resume.
Understanding Bioinformatics Internships
Bioinformatics sits at the intersection of biology, computer science, and statistics. Interns in this field work with genomic sequences, protein structures, clinical datasets, and high-throughput experimental outputs. The work requires comfort with command-line tools, scripting languages such as Python or R, and an understanding of biological questions that motivate the analysis.
The U.S. Bureau of Labor Statistics groups related occupations under computer and information research scientists and medical scientists, noting that these roles typically require graduate education for full-time positions. Internships serve as the entry point where students and career changers test whether they can apply computational methods to real biological problems before committing to a multi-year degree program.
The U.S. Department of Labor's O*NET OnLine describes the task profile for bioinformatics scientists, which includes developing software, analyzing molecular data, and collaborating with laboratory researchers. These tasks appear in internship postings in scaled-down form. An intern might write a pipeline script, clean a dataset, or produce a visualization that a senior scientist reviews.
Internships differ from coursework in three important ways. First, the data are messy and incomplete. Second, the timeline is driven by experimental progress, not a semester calendar. Third, the output must be useful to someone else, usually a principal investigator or a product team. Understanding these differences helps you set realistic expectations and choose programs that match your current skill level.
Where to Find Bioinformatics Internships
Federal Research Training Programs
The National Institutes of Health operates the Office of Intramural Training and Education, which coordinates research training opportunities across its intramural campuses. This office lists summer internships, postbaccalaureate fellowships, and graduate training programs for students at various stages. The NIH website describes these programs as pathways for research-career development and mentoring, making it a primary source for structured bioinformatics internships in government laboratories.
The National Science Foundation posts career opportunities on its official site, including scientific, program, administrative, and technical roles. While NSF primarily employs full-time staff, its funding portfolio supports university-based Research Experiences for Undergraduates programs that frequently include bioinformatics projects. Search the NSF award database for active REU sites in computational biology instead of relying only on the careers page.
Professional Society Job Boards
The American Society for Microbiology maintains a career services section that lists job postings, internship announcements, and professional development resources. Microbiology laboratories increasingly generate sequencing data that requires bioinformatics support, so these postings often include computational roles. The ASM career resources also describe networking opportunities at annual meetings where internship coordinators recruit candidates.
The Association of American Veterinary Medical Colleges provides career resources for veterinary education pathways. Veterinary diagnostic laboratories and animal health research centers employ bioinformatics interns to analyze pathogen genomes, track disease outbreaks, and support precision medicine initiatives. These positions suit students with an interest in animal health and computational biology.
University and Hospital-Based Programs
Many academic medical centers run summer research programs that accept external applicants. These programs typically require a transcript, a personal statement, and two letters of recommendation. Application deadlines cluster between December and February for summer placements. Check each program's eligibility rules because some restrict applicants to current students at partner institutions.
Hospital bioinformatics groups work with electronic health records, genomic diagnostics, and clinical decision support. Interns in these settings must complete HIPAA training and follow strict data governance protocols. The work offers exposure to regulatory constraints that academic laboratories do not face, which is valuable if you plan to work in clinical informatics.
Industry Internships
Biotechnology and pharmaceutical companies hire bioinformatics interns for product development, research, and data engineering teams. These positions are competitive and often require demonstrated proficiency with specific tools such as Nextflow, Snakemake, or cloud computing platforms. Company career portals list these roles, and professional networking platforms help you identify hiring managers.
Startup companies sometimes offer internships with broader responsibilities because teams are small. You might handle data cleaning, pipeline development, and client communication in a single placement. The tradeoff is less structured mentoring, so you must be comfortable asking questions and managing your own learning.
How to Prepare Before You Apply
Build Foundational Skills
Bioinformatics internships expect familiarity with at least one programming language, usually Python or R. You should be able to read and write scripts that manipulate tabular data, handle missing values, and produce basic plots. Version control with Git is a standard expectation because laboratories track changes to analysis code.
Command-line proficiency matters more than most applicants realize. Most bioinformatics tools run in a Unix environment, and you will need to navigate directories, run scripts, and manage files without a graphical interface. Practice on your own machine or a free cloud terminal before applying.
Biological domain knowledge distinguishes strong candidates. If you apply to a plant genomics lab, know the basics of genome assembly and annotation. If you apply to a clinical informatics group, understand study design and common statistical tests. Read recent papers from the laboratory you target and note the methods sections.
Create a Portfolio of Reproducible Work
A GitHub repository with clean, documented scripts carries more weight than a resume bullet point. Include at least one project that shows a complete analysis workflow: raw data input, processing steps, visualization, and a written interpretation. Comment your code as if a collaborator will run it without your help.
Public datasets from sources such as NCBI GEO or the UCSC Genome Browser provide raw material for practice projects. Reanalyze a published dataset and compare your results with the authors' findings. This exercise demonstrates that you can reproduce scientific results, which is a core skill in bioinformatics.
Write Targeted Application Materials
Your cover letter should name the specific laboratory, reference one of their recent papers, and explain how your skills address their research questions. Generic letters that describe your interest in bioinformatics without connecting to the lab's work are easily identified and discarded.
Your resume should list technical skills in a dedicated section, including programming languages, tools, and operating systems. For each project, state the biological question, the dataset, the methods, and the outcome. Quantify where possible, such as the number of samples processed or the runtime improvement achieved.
The Application Process
Tracking Applications and Deadlines
Create a spreadsheet with columns for program name, deadline, required materials, submission date, and follow-up date. Federal programs often have fixed deadlines, while university programs may review applications on a rolling basis. Missing a deadline eliminates you from consideration regardless of your qualifications.
Most programs require a transcript, a personal statement, and letters of recommendation. Request letters at least three weeks before the deadline and provide your recommenders with your resume, the program description, and a summary of your relevant work. This preparation helps them write specific letters.
Interview Preparation
Interviews for bioinformatics internships typically include a technical component. You may be asked to explain a past project, walk through your problem-solving approach, or complete a take-home coding exercise. Practice explaining your projects in plain language that a biologist can understand and in technical detail that a computational scientist expects.
Prepare questions about the lab's current projects, the mentoring structure, and the expected deliverables for the internship. These questions demonstrate genuine interest and help you assess whether the placement fits your goals.
Handling Rejection
Competition for bioinformatics internships is intense, and rejection is common. Request feedback when the program offers it, and use the gap to strengthen your portfolio. Many successful applicants apply to multiple cycles before securing a placement. Treat each application cycle as practice for the next.
What to Do During the Internship
Set Clear Expectations Early
During your first week, meet with your supervisor to define the project scope, the expected deliverables, and the timeline. Ask about the format for progress updates and the preferred method for asking questions. Document these agreements in writing so both parties share the same understanding.
Identify the computational resources you will use, including servers, storage, and software licenses. Confirm whether you have access to the necessary systems and who to contact when you encounter access problems. Resolving these logistics early prevents wasted time later.
Keep a Laboratory Notebook
Maintain a digital notebook that records your commands, parameters, and reasoning for each analysis step. This record serves three purposes. It helps you reproduce your own work when results need revision. It provides material for your final report. It demonstrates professional practice that supervisors notice.
Record also what you did but why you did it. When you choose a particular normalization method or filtering threshold, note the rationale. This context is invaluable when you revisit the analysis weeks later or when a collaborator asks about your decisions.
Ask Questions Strategically
Good questions show engagement, but poorly timed questions disrupt workflow. Before asking, check whether the answer is available in the documentation, the code comments, or the lab's shared resources. When you do ask, frame the question with what you have already tried and where you are stuck.
Batch routine questions into scheduled check-ins instead of interrupting constantly. Save urgent questions for genuine blockers that prevent progress. This balance respects your supervisor's time while ensuring you get the help you need.
Build Relationships Beyond Your Project
Introduce yourself to other lab members and learn about their projects. Attend lab meetings and journal clubs even when the topic is outside your immediate work. These interactions build your professional network and expose you to the breadth of bioinformatics research.
Ask your supervisor for introductions to collaborators in other departments. A brief informational conversation with a clinician, a statistician, or a software engineer can broaden your understanding of how bioinformatics fits into the larger research enterprise.
Turning the Internship Into Career Momentum
Deliver a Final Report and Presentation
Most programs expect a written summary and a presentation of your work. Treat these deliverables as professional products, not academic exercises. Structure the report with an introduction that states the biological question, a methods section that a reader could reproduce, results with clear figures, and a discussion of limitations and next steps.
Practice your presentation with a colleague before delivering it to the lab. Time yourself and prepare answers to likely questions. A polished final presentation leaves a lasting impression and provides a concrete artifact for your portfolio.
Request a Letter of Recommendation
Ask your supervisor for a letter of recommendation while your work is fresh in their memory. Provide them with a summary of your contributions, the skills you demonstrated, and the outcomes you achieved. This material helps them write a specific and effective letter.
If your internship was productive, ask whether the laboratory has opportunities for continued collaboration. Some interns transition to part-time remote work, thesis projects, or full-time positions. Even when no position exists, your supervisor may refer you to colleagues with openings.
Update Your Portfolio and Resume
Add your internship project to your portfolio with the same documentation standards you used for practice projects. Include the biological context, the data sources, the methods, and the results. If the work is published or presented, link to the public record.
Update your resume to describe the internship in terms of skills and outcomes. State the tools you used, the scale of the data you processed, and the conclusions your analysis supported. These specifics carry more weight than a generic description of your responsibilities.
Common Failure Patterns and How to Avoid Them
Applying Without Domain Context
Applicants who submit identical materials to every program signal that they have not researched the laboratory's work. Programs seek interns who understand the biological questions and can contribute to the specific research agenda. Read recent publications and tailor your application to each program.
Overvaluing Tool Knowledge Over Biological Reasoning
Knowing the latest deep learning framework does not compensate for an inability to interpret a differential expression result. Supervisors want interns who can connect computational outputs to biological meaning. Practice interpreting results in biological terms and be ready to discuss the limitations of your analysis.
Underestimating Data Management
Bioinformatics projects generate intermediate files, versioned scripts, and multiple analysis iterations. Interns who do not organize these artifacts create confusion and waste time. Adopt a consistent file naming convention, document your directory structure, and use version control from the first day.
Failing to Communicate Progress
Supervisors cannot help with problems they do not know about. Interns who struggle silently for weeks produce poor outcomes and negative evaluations. Provide regular progress updates, flag obstacles early, and ask for guidance when you are stuck.
Records and Measurements to Track
Maintain a weekly log that records your tasks, hours, and progress toward project milestones. This log supports your final report, provides material for your resume, and helps you identify patterns in your productivity. Review it weekly and adjust your approach when you notice inefficiencies.
Track the computational resources you use, including runtime, memory, and storage for each analysis. This information is useful for optimizing your pipelines and for reporting resource needs to your supervisor. It also demonstrates professional attention to reproducibility and efficiency.
Document every decision that affects your analysis, including parameter choices, filtering thresholds, and data exclusions. This documentation is essential for reproducibility and for defending your results to collaborators. It also protects you if a supervisor questions a particular choice.
Welfare and Safety Context
Bioinformatics internships in animal health settings involve handling sensitive data from veterinary patients and research animals. Follow institutional protocols for data security and confidentiality. Never share patient-level data outside approved channels, and complete all required training before accessing restricted datasets.
Laboratory work in bioinformatics may involve collaboration with wet-lab colleagues who handle biological samples. Follow institutional safety rules when visiting laboratory spaces, and respect the protocols that govern sample handling and disposal. Your computational work supports their experimental work, and professional conduct in shared spaces matters.
If your internship involves clinical data, understand the regulatory framework that governs its use. The Health Insurance Portability and Accountability Act applies to identifiable health information in the United States. Institutional review boards oversee research involving human subjects. Your supervisor can direct you to the relevant training and policies.
Professional Escalation Criteria
Some situations during an internship require escalation beyond your immediate supervisor. If you observe data fabrication, falsification, or plagiarism, report it through your institution's research integrity office. These situations are rare but serious, and institutions have established procedures for handling them.
If you experience harassment, discrimination, or unsafe working conditions, contact your institution's human resources office or ombudsperson. Federal training programs and professional societies have policies against such conduct, and you have the right to work in a respectful environment.
If a supervisor asks you to perform work outside your training or to misrepresent your contributions, document the request and seek guidance from a trusted mentor. Professional integrity matters more than completing a placement, and institutions support interns who raise legitimate concerns.

How to Choose Between Competing Internship Offers Using a Decision Matrix
Receiving multiple internship offers creates a different problem than receiving none. Students and career changers often accept the first offer or the one with the highest stipend without systematically comparing what each placement will deliver for their long-term goals. A structured decision matrix removes emotional pressure and forces you to evaluate each offer against the same criteria.
Define Your Evaluation Criteria Before Offers Arrive
Write your criteria before you submit applications, not after offers arrive. This prevents rationalizing a weak fit because the offer feels flattering. Start with five to eight criteria that matter for your specific situation. Common criteria include project relevance to your target career, mentoring quality, technical skill development, data access and infrastructure, publication or portfolio potential, stipend and relocation support, duration and schedule flexibility, and conversion rate to full-time positions.
Assign each criterion a weight from 1 to 5 based on your priorities. A career changer targeting clinical bioinformatics might weight clinical data exposure at 5 and stipend at 2. A current undergraduate exploring research might weight mentoring at 5 and publication potential at 4. The weights reflect your goals, not what you think employers want to hear.
Build the Scoring Matrix
Create a table with one row per offer and one column per criterion. Score each offer from 1 to 5 on each criterion using evidence from your interviews, program materials, and conversations with current or former interns. A score of 1 means the offer fails the criterion, 3 means it meets the baseline, and 5 means it clearly exceeds expectations.
Multiply each score by the criterion weight and sum the totals for each offer. The highest total indicates the best fit according to your stated priorities. This process does not guarantee a perfect choice, but it forces you to articulate why one offer beats another instead of relying on gut feeling or external pressure.
Gather Evidence for Each Criterion
For project relevance, ask during the interview what specific datasets you will work with and what biological questions the project addresses. Request the project description in writing if the program has not provided one. Compare the project against the job postings you plan to target after the internship.
For mentoring quality, ask who supervises your daily work and how often you meet. The NIH Office of Intramural Training and Education describes mentoring as a core component of its research training programs, and structured programs typically document supervision expectations. Ask whether you will work directly with a principal investigator or with a postdoctoral fellow or graduate student. Direct PI mentoring offers different advantages than day-to-day supervision by a senior trainee.
For technical skill development, list the tools and methods the project requires. Compare this list against the skills in your target job postings. The U.S. Department of Labor's O*NET OnLine describes the technology skills for bioinformatics scientists, which include programming languages, database management systems, and analytical software. A project that teaches you a new language or a cloud platform may be worth more than a project that repeats skills you already have.
For data access, ask whether you will work with real experimental data or simulated data. Real data introduces the messiness that defines professional bioinformatics, including missing values, batch effects, and annotation errors. Ask about compute resources, storage limits, and whether you can access the cluster remotely after the internship ends.
For publication potential, ask whether the project is part of a manuscript in preparation or a grant-funded study with expected deliverables. Be realistic about timelines. A project that produces a poster at a departmental symposium may be more achievable than one that promises a journal publication within a summer.
Compare Non-Negotiables Separately
Some factors are not tradeable. If an offer requires relocation and you cannot relocate, that offer is eliminated regardless of its score. If a program requires you to be a current student and you are a career changer, the eligibility rule removes it from consideration. Apply these filters before scoring to avoid wasting effort on impossible options.
Stipend and funding matter for practical reasons, but they should not dominate the decision unless the difference creates genuine hardship. The U.S. Bureau of Labor Statistics notes that education and experience affect earnings in research occupations, and an internship that builds more relevant experience may justify a lower stipend if you can cover your costs.
Use the Matrix in Conversation
When you have a top choice, the matrix helps you negotiate or ask clarifying questions. If the second-ranked offer scores higher on mentoring but lower on project relevance, you can ask the top-ranked program about supervision structure before accepting. This turns the matrix into a communication tool instead of a private calculation.
If two offers score nearly identically, revisit your weights. The tie usually means your criteria do not distinguish the options, so add a criterion you omitted, such as geographic location, alumni network, or the specific reputation of the laboratory in your target subfield. A single additional criterion often breaks the tie.
Record Your Decision Rationale
Write a short paragraph explaining why you chose one offer over the others, referencing the matrix scores. Keep this document for your own records. You will likely face a similar decision after graduate school or in your first job search, and your reasoning will help you refine your criteria. The document also provides material for interviews when employers ask why you chose a particular internship.
Revisit the Matrix During the Internship
The matrix serves as a baseline for evaluating whether the internship meets your expectations. At the midpoint, score the actual experience against the criteria you used to choose. If the project changed scope or the mentoring did not materialize, note the discrepancy and discuss it with your supervisor. This practice turns the decision framework into an ongoing evaluation tool instead of a one-time exercise.
Common Mistakes in Comparing Offers
The most common mistake is weighting stipend too heavily at the expense of skill development. A summer stipend difference of a few thousand dollars rarely matters five years into a career, but the difference between learning cloud-based genomics pipelines and spending the summer reformatting spreadsheets can shape your job prospects.
Another mistake is ignoring the daily supervision structure. A prestigious laboratory where you rarely meet your supervisor may deliver less learning than a smaller group with weekly one-on-one meetings. The NIH Office of Intramural Training and Education emphasizes that effective mentoring includes regular feedback and professional development, beyond project oversight.
A third mistake is assuming the offer with the most impressive name is the best fit. A well-known institution may place you on a peripheral project with limited responsibility, while a less famous group may give you ownership of a meaningful analysis. The matrix forces you to evaluate the actual work, not the brand.
When to Decline an Offer
Declining an offer is appropriate when the matrix reveals a clear mismatch with your goals or when accepting would prevent you from pursuing a better opportunity. Decline promptly and professionally, thanking the program for the offer and explaining briefly that you have accepted another position. Programs understand that candidates weigh multiple offers, and a courteous decline preserves the relationship for future applications.
If you decline an offer because of concerns about the project or mentoring, you do not need to share those concerns in detail. A simple statement that the position does not fit your current goals suffices. Burning bridges by criticizing the program serves no purpose.
Frequently Asked Questions
Do I need a graduate degree to get a bioinformatics internship?
No. Many programs accept current undergraduates, and some accept career changers without formal biology training. The U.S. Bureau of Labor Statistics notes that full-time research roles typically require graduate education, but internships serve as training pathways for students at various stages. Focus on demonstrating relevant skills and motivation instead of waiting for an advanced degree.
What programming languages should I learn before applying?
Python and R are the most common languages in bioinformatics, and proficiency in at least one is expected. The U.S. Department of Labor's O*NET OnLine lists programming skills among the core competencies for bioinformatics scientists. Learn version control with Git and basic command-line usage in a Unix environment, as these tools appear in most laboratory workflows.
How competitive are bioinformatics internships?
Competition varies by program type. Federal training programs at the NIH receive many applications for limited slots, while smaller laboratory positions may have fewer applicants. The NIH Office of Intramural Training and Education describes its programs as selective research training opportunities. Apply to multiple programs and treat each application cycle as practice.
Can I do a bioinformatics internship remotely?
Some programs offer remote or hybrid formats, particularly for computational work that does not require laboratory access. Federal and university programs have varied policies, so check each posting for location requirements. Remote internships require strong self-management skills and reliable communication with your supervisor.
What if I have a biology background but limited programming experience?
You can build programming skills through online courses, practice projects, and open-source contributions before applying. The American Society for Microbiology career resources describe professional development pathways that include computational skills. Start with small projects that combine your biological knowledge with basic scripting, then expand your portfolio.
How do I find internships in animal health bioinformatics?
The Association of American Veterinary Medical Colleges provides career resources for veterinary education pathways, and veterinary diagnostic laboratories often post bioinformatics positions. Search for positions at veterinary schools, animal health research institutes, and government agencies that monitor animal diseases. These roles combine computational work with applications in animal health.
What should I do if my internship project fails?
Project failure is a learning outcome, not a personal failure. Document what you tried, what went wrong, and what you would do differently. Discuss the results with your supervisor and ask for guidance on alternative approaches. A thoughtful analysis of failure demonstrates scientific maturity and often impresses supervisors more than a superficial success.
How do I turn an internship into a full-time job?
Deliver high-quality work, communicate regularly, and build relationships beyond your immediate project. Ask your supervisor about opportunities for continued collaboration and request a letter of recommendation while your work is fresh. The NIH Office of Intramural Training and Education describes mentoring as a core component of its programs, and strong mentors often advocate for their interns when positions open.
