I apply a macroecological perspective to understand large-scale disease dynamics and global patterns of biodiversity. The tools of my trade are data science and computational methods including statistical modeling, machine learning, and phylogenetic comparative methods. I primarily study zoonotic diseases (i.e., disease that can spread from wild animals to humans and domestic animals) and the biodiversity of terrestrial vertebrates (particularly amphibians, reptiles, and mammals). Current research topics include (1) risk factors for spillover and outbreak of African filoviruses such as Ebola, and (2) global patterns of biodiversity in squamates (lizards and snakes).
