Assistant Professor of Biology
Areas of Expertise: Genetics, neuroscience, Drosophila research, neurodevelopmental genetics

The overarching goal of my research is to examine genetic influences on nervous system development and function. In particular, I am interested in understanding how genetic diseases can disrupt appropriate developmental pathways and thereby alter normal nervous system function.

I take an interdisciplinary approach to these questions, using behavioral, molecular, and genetic techniques to address nervous system form and function. By examining the genetic system of Drosophila melanogaster, otherwise known as the fruit fly, I manipulate the nervous system during development and into adult life to learn more about how changes occur.

Through my research, I hope to develop a deeper understanding of nervous system perturbations caused by diseases so we can potentially identify ways to eliminate or mitigate the effects of genetic diseases affecting humans.
