Davis Lab Members and Affiliates
Lea K. Davis, PhD Assistant Professor Department of Medicine Division of Genetic Medicine Department of Psychiatry and Behavioral Sciences
Department of Biomedical Informatics
Department of Molecular Physiology and Biophysics
Vanderbilt University Medical Center
Work in our lab employs a population level approach to investigate the genetic basis of a wide range of complex traits and disease phenotypes. Our research aims to discover how polygenic risk, rare variant risk, and environment interact to contribute to common psychiatric diagnoses and their comorbidities. To accomplish this goal, we apply genomic and bioinformatic approaches to biobank data and phenotypes extracted from the electronic health record. In addition to my work in psychiatric genomics, I have a long-standing interest in research ethics, mentoring, and community organizing. I strive to create an inclusive environment in my lab and am enthusiastic about mentoring and teaching!
When I am not working, I am usually cooking, gardening, reading, community organizing, or out skating with the Nashville Junior Roller Derby for which I serve as the Executive Director!
