Research Overview: 

Hernandez Lab research focuses on three main areas:

  1. Basic population genomics: we seek to use current patterns of human genetic variation from whole genome sequencing to understand the evolutionary history of human populations.
  2. Disease susceptibility in complex populations: We strive to leverage evolutionary signals in patterns of genetic variation to uncover the meaningful associations with phenotypic variation.
  3. Host-pathogen interactions: We develop tools to leverage patterns of genetic diversity within populations and divergence across phylogenies to learn more about the genetic targets of host-pathogen interactions.
Primary Thematic Area: 
Human Genetics
Secondary Thematic Area: 
None
Research Summary: 
We study patterns of human genetic variation using large-scale data and the tools of population genomics.
