I am a postdoc in the lab of Florian Engert at Harvard University and generally interested in how nervous systems compute and control behavior. In my work, I seek to understand the neural basis of perceptual decision-making, using the larval zebrafish as a model. Through a combination of behavioral experiments, calcium imaging, anatomical analyses, and computational modeling, I hope to unravel some general principles of the behavior that can also be tested in other animal models.
