About

About Me 

I am a biologist by training who has always been interested in animal behavior and the neural circuits which execute motor actions. I am interested in investigating how fish swim using in vivo activity monitoring such as calcium imaging and electrophysiology in the intact animal, to watch motor circuits function in real time.

Research

Current Research


Larval zebrafish swim to move around their environment, find food, and escape from predators. We are interested in the neural circuits in the brain and spinal cord which control that locomotion. Larval zebrafish can be genetically manipulated so we can mark certain neurons with colors or calcium activity monitors, and view them through their transparent bodies, while they perform motor actions. Using these techniques, we try to understand what specific circuits are essential for performing different motor actions, and how those circuits are wired together.
