About
I am a biological anthropologist who studies primate behavior and ecology. My research broadly focuses on the influence of ecology and environment on primate distribution and habitat use. I am particularly interested in understanding the effects of environmental differences, such as horizontal and vertical gradients in tropical forest structure and climate, on primate movement and use of 3-dimensional space.
My current research is based in Gunung Palung National Park, West Kalimantan, Indonesia. My work at Gunung Palung is focused on uncovering how factors such as forest structure, food availability, and predator presence impact ground use (terrestriality) in predominantly
arboreal primates.
Current and Previous Research
LiDAR and Forest Structure
Using LiDAR-derived forest structure metrics as a predictor of arboreal primate ground use.
Gunung Palung National Park, Indonesia
Terrestriality Across the Primate Order
Using Bayesian modeling to determine the ecological factors that influence ground use in primates.
Tamarin Spatial Ecology
Using GIS to understand group ranging and intergroup conflict between two tamarin species.
