From personalized cancer treatments to AI-powered surgical diagnostics, bioinformatics is transforming how we understand and treat disease
Imagine trying to read a book with 3 billion letters without spaces, punctuation, or chapter breaks—this was the challenge scientists faced when first sequencing the human genome.
Today, bioinformatics—the interdisciplinary field that combines biology, computer science, and information technology—has not only helped read this book but is understanding its grammar, interpreting its stories, and even learning how to edit its chapters. We've transitioned from simply cataloging biological parts to understanding their functions and interactions in complex systems, with profound implications for medicine, agriculture, and environmental science 1 .
