• Collective foraging and emergent sensing strategies
• Social communication and information flow in animal societies
• Effects of noise on marine mammals

I am a behavioral ecologist with expertise in bioacoustics, sensory ecology, and biologging. I work broadly to understand how social animals function - how they forage individually and in groups, how they communicate and coordinate motion and activity with conspecifics, and how increasing anthropogenic activities such as underwater noise or marine development affects such life functions in the Anthropocene. I work closely with the Bioacoustics and Behavioral Ecology Lab led by Professor Susan Parks.
