Research

I am a Ph.D. candidate in the Bob and Norma Street Environmental Fluid Mechanics Laboratory at Stanford University studying the fluid dynamics of biological propulsion and collective motion in stratified flows. I use laboratory experiments with novel flow visualization and measurement techniques to understand the fluid dynamics within swarms and the potential impacts of collective swimmers on the surrounding water column.
