I am interested in how populations diverge and adapt to the environments they encounter. To identify and characterize specific genes and pathways that underlie adaptive change, I combine statistical and genomic approaches with knowledge from organismal and ecological studies. My work utilizes a range of technological and analytical methods and involves collaborations with researchers who climb Mexican volcanoes and explore Caribbean Islands for exotic species who are specially adapted to their extreme environments. By correlating genetic changes to phenotypic outcomes using population genomics, I hope to link genomic changes to sources of selection.
