Research Interests
1. Methods for estimating heritability and investigating genetic architecture of complex traits. Recent work focuses on the heritability and genetic architecture of human psychiatric disorders, including identifying genetic variants that contribute to disorder liability, understanding gene-by-environment interactions, and testing how these factors influence risk prediction.听
2. Selection and adaptation. Identifying quantitative and molecular signatures of selection, both recent positive selection and purifying selection. Using large-scale reciprocal transplant experiments to test gene-by-environment interaction hypotheses and to understand how environments shape complex traits. Much of this work has been with the ecologically and economically important tree听genus,听笔辞辫耻濒耻蝉,听but also with听Salix.
