   Research Interests

I am interested in evolution and conservation biology, particularly in (1) the adaptive significance of genetic diversity, (2) how increased population fragmentation and isolation influences population processes at both temporal and spatial scales, and (3) the precision and accuracy of methods in describing such processes at or below the species level
