Welcome to my research website! I am a Professional Researcher in the Ecology, Evolution, and Marine Biology Department at the University of California, Santa Barbara.

My research uses integrative approaches to understand how animals gather information and make decisions in contexts from competition to mate choice. I study this assessment from its mechanisms (biomechanics and physiology), through its behaviors, up to its implications for ecology and evolution.

I am also passionate about connecting my research to the broader community through teaching, mentoring, and outreach.
