What our community says
I found my PhD position through TheBiologyBro in under two weeks. The job alerts are incredibly targeted — nothing irrelevant, just exactly what I was looking for.
The MCQ bank helped me prepare for my qualifying exams. Over 2,000 questions with detailed explanations — genuinely the most comprehensive biology revision resource I've found.
The hemocytometer calculator alone saves me 15 minutes every day in the lab. The science news feed is a brilliant addition — concise, accurate, and actually relevant.
We exist for biologists
TheBiologyBro was built by a biologist, for biologists. We saw how fragmented the resources were — jobs scattered across dozens of sites, revision materials behind paywalls, lab tools that cost hundreds, and science news buried in dense abstracts.
Today we serve over 120,000 life science professionals and students globally, helping them land positions, pass exams, work more efficiently in the lab, and stay current with the science that matters.
Community First
Every decision we make starts with one question: does this genuinely help biologists?
Accuracy Matters
All content is expert-reviewed. We'd rather publish less than publish wrong.
Global Reach
Jobs and tools for every country, every career stage, every specialism.
Practical Focus
Real tools for real workflows — no fluff, no filler.
