Computational Biology at Khoury College of Computer Sciences
Uncovering the secrets of life through the power of computation
Computational biology bridges the gap between computer science and life sciences. Khoury College researchers explore both fundamental and applied questions in all aspects of studies of living systems. Their interdisciplinary approach brings together multiple computer science disciplines, including machine learning, computer vision, statistics, data science, and data visualization, as well as connections to programming languages, mathematics, physics, and network sciences.
Computational biology uses the power of large and complex datasets generated by modern biotechnologies to make complex biological processes legible and to provide insight for life science researchers, clinicians, policymakers, and educators.
Using biological data to explore fundamental questions
Computational biology fuels discoveries across a wide range of fields, including studies of genomes, proteomes, metabolomes, diagnosis and prognosis of disease, discovery of molecular mechanisms of disease, vaccines, and therapeutics, and advances toward personalized medicine. Computational biology is also providing insights into agriculture, climate science, and ecosystem analysis.

Eliater: A Python package for estimating outcomes of perturbations in biomolecular networks (Bioinformatics, 2024)
Authors: Sara Mohammad-Taheri, Pruthvi Prakash Navada, Charles Tapley Hoyt, Jeremy Zucker, Karen Sachs, Benjamin M. Gyori, Olga Vitek
This research introduces and showcases Eliater, a Python package for estimating the effect of perturbation of an upstream molecule on a downstream molecule in a biomolecular network.
Beyond protein lists: AI-assisted interpretation of proteomic investigations in the context of evolving scientific knowledge (Nature Methods, 2024)
Authors: Benjamin M. Gyori, Olga Vitek
Mass spectrometry-based proteomics provides broad and quantitative detection of the proteome, but its results are mostly presented as protein lists. Artificial intelligence approaches will exploit prior knowledge from literature and harmonize fragmented datasets to enable mechanistic and functional interpretation of proteomics experiments.
