RESEARCH

1/6

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.​

  • Genomics & computational biology

  • Applied statistical/machine learning

  • Integrative analysis of large-scale genomics and biomedical data

  • Genome-wide molecular networks

  • Age-specificity and sexual dimorphism in health and disease

  • Cross-species models for human traits and diseases

  • Genetic heterogeneity of complex disease and precision medicine

 

Our overarching goal is two-fold: 1) gain more nuanced and accurate insights into the genes and networks underlying physiology, complex diseases, and clinical phenotypes, and 2) use these insights to mechanistically link an individual's genomic profiles to a precise assessment of her/his physiological/clinical traits, risks, and outcomes.
