Introduction
I am interested in the evolution and distribution of biodiversity across various spatial and temporal scales. My lab has 4 major themes: 1) macro-evolution (estimating speciation, extinction and dispersal); 2) molecular phylogenetics (applying next-generation sequencing to infer species relationships); 3) biodiversity analyses (mapping and understanding patterns of taxonomic, phylogenetic and functional diversity); and 4) bioinformatics (development of open-source software).
