Patrick McGrath's research group is interested in understanding the genetic basis of heritable behavioral variation. In the current age, it has become cheap and easy to catalog the set of genetic differences between two individuals. But which genetic differences are responsible for generating differences in innate behaviors, including liability to neurological diseases such as autism, bipolar disease, and schizophrenia? How do these causative genetic variants modify a nervous system? Besides their role in disease, genetic variation is the substrate for natural selection. To understand how behavior evolves, we must understand how it varies.

    Mostbiological traits have a strong genetic, or heritable, component. Understanding how genetic variation influences these phenotypes will be important for understanding common, heritable diseases like autism.However, the genetic architecture controlling most biological traits is incredibly complex - hundreds of interacting genes and variants combine in unknown ways to create phenotype.The McGrath lab is interested in using fundamentalmechanistic studies inC. elegansto identify, predict, and understand how genetic variation impacts the function of the nervous system.We are studying laboratory adapted strains and harnessing directed evolution experiments to understand how genetic changes affect development, reproduction, and lifespan. We combine quantitative genetics, CRISPR/Cas9, genomics, and computational approaches to address these questions.We believe this work will lead to insights into evolution, multigenic disease, and systems biology.
