RESEARCH
We work at the intersection of
biology + computer science + statistics + applied mathematics
The Krishnan lab develops and applies genomics/computational approaches to find mechanistic explanations for how our genome relates to health and disease.
We use statistics and machine learning to analyze large-scale data and build genome-scale predictive models about the genetic basis of biomedical phenomena.
We work in synergy with experimental and clinical researchers to motivate our methods and put our computational models/predictions to test in human and model systems.
Our overarching goal is two-fold:
-
Gain more nuanced and accurate insights into the genes and networks underlying physiology, complex diseases, and clinical phenotypes, and
-
Use these insights to mechanistically link an individual's genomic profiles to a precise assessment of her/his physiological/clinical traits, risks, and outcomes.
