What is bioinformatics, really? A biologist's map

Ask ten people what bioinformatics is and you'll get ten answers — most of them either vague or terrifying. Let's fix that. At its core, bioinformatics is using computers to make sense of biological data. That's it. The complexity comes from the sheer scale and messiness of that data.

So what is it, actually?

Modern biology produces enormous datasets: a single genome is three billion letters, and a sequencing run can generate hundreds of millions of reads. No human can eyeball that. Bioinformatics is the toolkit — the code, the algorithms, the statistics — that turns those raw numbers into biological answers: which gene is broken, which mutation causes disease, how two species are related.

Where you fit in

You do not need to become a computer scientist. You need enough of a few skills to be dangerous:

• A scripting language (Python or R) to manipulate data
• The Linux command line, where most tools live
• Enough statistics to not fool yourself
• Domain knowledge — the biology you already have

The best bioinformaticians are biologists who learned to code, not coders who learned some biology.

That last part is the good news. If you understand the biology, you're already halfway there. The coding is learnable — and it's exactly what we teach, step by step.
