As biology produces more data than ever before, scientists rely on bioinformatics to uncover patterns hidden within DNA, proteins, and other biological systems.
What happens when biology generates more data than humans can possibly analyze on their own?
Modern biological experiments can produce billions of data points at once, from DNA sequences to protein interactions. Turning that massive amount of information into meaningful discoveries requires powerful computational tools.
That’s where bioinformatics comes in.
Bioinformatics combines biology, computing, statistics, and artificial intelligence to organize and analyze complex biological datasets. By using computer algorithms and advanced data analysis, scientists can detect patterns and relationships that would otherwise remain indecipherable.
The field first gained momentum in the 1990s as researchers worked to sequence the human genome. Today, bioinformatics is essential across nearly every area of modern biology, from studying how proteins function to comparing DNA across species and understanding how diseases develop.

Melanie Wielert, a data scientist in the Zeitlinger Lab at the Stowers Institute, helps analyze these massive biological datasets to uncover patterns hidden within DNA.
In the latest installment of the Institute’s BioBasics video series, Wielert explains how bioinformatics allows scientists to combine programming, statistics, and computational tools to make sense of the complexity.
“Without these bioinformatics tools, we’d just have mountains of raw data,” said Wielert.
In the Zeitlinger Lab, researchers use bioinformatics to study genomics, the science of DNA and genes. Their work focuses on how certain pieces of DNA act like switches that control when genes turn on or off.
By uncovering these patterns, scientists hope to better understand how genes function in health and disease. This knowledge could eventually help researchers develop new strategies for studying aging, preventing disease, and advancing personalized medicine.
As biological technologies rapidly advance and produce even larger datasets, the role of bioinformatics will only become more important.
