Research

Research Summary/Interests

I am interested in the interaction between genes and the nutrient environment and how this interaction influences the health and fitness of populations. The goal of my current research is to understand why some populations can thrive on an unbalanced diet while others show decline in health and fitness. To do this I use biochemistry, physiology, life history traits, and population genetics to study structured populations of dietary specialist and dietary generalist Drosophila flies.
