Mammals Revealed - an exhibit I curated at the NYSM.
 

As a Post Doc I assisted with a lion research project in Tsavo, Kenya. Here I'm watching a pride of lions feeding on a buffalo calf.

For my Ph.D. I studied kinkajous and olingos in Panama. This picture shows me releasing an olingo from a trap.

As an undergraduate intern with the American Museum of Natural History I helped with a mammal survey in French Guiana.
