Summary

I am evolutionary biologist interested in systematics, biogeography, and diversification patterns and processes that have shaped the Asian tropical biodiversity. To study this, I use various tools including molecular and morphology-based phylogenies, divergence time estimation using fossils, historical biogeography analyses, phylogenetic comparative methods, and species distributional modeling. I have focused on two evolutionarily distinct groups: a. tropical centipedes, which are ancient (400 million years), low dispersing, terrestrial, carnivorous, and morphologically conserved taxa; b. butterflies, which are relatively young (65 million years), vagile, and morphologically diverse with complex life histories.
