Bioinformatics & Computational Biology

Applying computational methods to analyze biological data — from genomic sequences to protein structures

Overview

Bioinformatics and computational biology sit at the intersection of computer science, statistics, and the life sciences. This field uses algorithms, machine learning, and data analysis to make sense of the massive datasets generated by modern biology — genome sequences, protein structures, gene expression patterns, and clinical records. If biology generates the questions and the data, bioinformatics builds the tools to find the answers.

The field has grown explosively since the Human Genome Project, and today bioinformatics is essential in drug discovery, personalized medicine, agricultural biotechnology, and epidemic tracking. Students in this major learn to write code, build statistical models, and understand enough molecular biology to know what questions matter. It is a field where a single well-designed algorithm can accelerate research that would take a wet lab years to complete.

Several universities have built world-class programmes in this space. MIT and Harvard jointly operate the Broad Institute, one of the most influential genomics research centers globally, and students in computational biology benefit from direct access to its datasets and faculty. Stanford’s Biomedical Informatics programme bridges the medical school and computer science department, emphasizing clinical applications of computational methods. ETH Zurich offers a dedicated Computational Biology and Bioinformatics master’s track with strong ties to the Swiss Institute of Bioinformatics. The University of Cambridge integrates bioinformatics into its Natural Sciences Tripos, and the European Bioinformatics Institute (EMBL-EBI) located nearby provides unmatched research infrastructure. In Asia, the University of Tokyo’s Human Genome Center has been a leader in cancer genomics and precision medicine research.

In Singapore

In Singapore, NUS offers a Bachelor of Computing in Computational Biology through the School of Computing — one of the few undergraduate programmes in Asia that combines rigorous computer science training with life sciences. The programme spans 11 departments across three faculties, giving students unusually broad interdisciplinary exposure. Singapore’s investment in biomedical sciences through A*STAR and Biopolis creates strong research and industry pathways for graduates.

Is This Right For Me?

Honest self-assessment to help you decide

WorkloadModerate to heavy—expect 15–22 hours per week outside lectures split between biology coursework, programming assignments, and data analysis projects. The challenge is the breadth: you need to keep up with two disciplines simultaneously.
Math LevelModerate to high—strong statistics and probability are essential. Linear algebra and discrete mathematics come up regularly. You won’t do as much pure math as AI students, but more than biology students.
CreativityMore structured than pure biology (algorithms and pipelines follow strict logic) but creative in how you frame biological questions computationally and design analysis workflows.
TeamworkMix—programming assignments and data analysis are often solo, but research projects are collaborative, typically pairing computational and experimental biologists.

You'll thrive if...

  • You’re equally fascinated by biology and computing and want a career that uses both every day
  • You enjoy detective work—sifting through massive datasets to find meaningful biological patterns
  • You’re comfortable with interdisciplinary thinking and switching between biological and computational frameworks
  • You find the idea of using code to understand disease, evolution, or genetics genuinely exciting
  • You’re patient with complexity—biological data is messy, noisy, and rarely behaves as expected

Might not be for you if...

  • You strongly prefer one discipline—bioinformatics requires genuine engagement with both biology and computing, not just tolerance of one
  • You dislike working with imperfect data—biological datasets are inherently noisy and incomplete
  • Heavy programming feels tedious—you’ll write code daily, often debugging data pipelines for hours
  • You want a field where results are immediately visible—bioinformatics analysis can take weeks before yielding insights
  • Abstract statistics makes you uneasy—the field relies heavily on probabilistic reasoning and statistical testing

A Day in the Life

What a typical week actually looks like

A typical week in Year 2 of a bioinformatics programme sits at the intersection of biology and computer science. Monday starts with a molecular biology lecture covering gene regulation and epigenetics—you’re learning how cells decide which genes to turn on and off, and why this matters for understanding cancer. After lunch, you move to an algorithms lab where you implement the Smith-Waterman local alignment algorithm in Python. It’s a strange feeling using dynamic programming to match DNA sequences when just two hours ago you were learning about the biology those sequences encode.

Tuesday and Wednesday are a mix of computational and biological coursework. A biostatistics lecture covers multiple testing correction—why running thousands of statistical tests on genomic data requires methods like Bonferroni or false discovery rate control. Your computational genomics course has you working with real RNA-seq data from a published cancer study, using tools like STAR for read alignment and DESeq2 for differential expression analysis. The datasets are enormous—millions of sequencing reads—and you learn to work on the university’s high-performance computing cluster, writing bash scripts to submit batch jobs.

Thursday brings a structural biology lecture on protein folding and a bioinformatics journal club where students present recent papers. This week, someone presents a study using AlphaFold predictions to identify drug targets for antibiotic-resistant bacteria. Friday is project time—your team is building a pipeline to identify genetic variants associated with drug response in a pharmacogenomics dataset. You spend the afternoon debugging a VCF file parser and arguing with your teammate about the best variant annotation tool. By the weekend, you’re running your pipeline on test data, checking that your results match published benchmarks, and reading a paper on graph-based genome representations for Monday’s class.

Getting In — Admissions Guide

How competitive is this major and how to stand out

Competitiveness: Moderate

Bioinformatics undergraduate programmes are less competitive than pure CS but require a strong combination of biology and mathematics. At top programmes like ETH Zürich, University of Toronto, and UC San Diego, you’ll need strong grades in both biology and mathematics. Many students enter through biology or CS programmes and specialize later, which reduces direct admissions pressure.

What Strengthens Your Application

  1. 1Strong grades in both biology and mathematics—demonstrating the dual aptitude is critical
  2. 2Programming experience, especially in Python or R, with a GitHub portfolio showing any computational work
  3. 3Laboratory or research experience in a biology, chemistry, or biomedical setting
  4. 4Completion of Rosalind bioinformatics challenges or similar computational biology projects
  5. 5A personal statement that clearly articulates why you want to combine biology with computation

Common Mistakes to Avoid

  • Presenting yourself as purely a biologist with no computational interest, or purely a programmer with no biology knowledge
  • Underestimating the mathematics required—bioinformatics involves serious statistics and algorithms
  • Not demonstrating awareness of what bioinformatics actually involves day-to-day

Interview & Admission Tests

Some programmes ask about motivation for the interdisciplinary combination. Be prepared to discuss a biological question you find interesting and how computation could help answer it.
