Navin Pokala’s interests are at the intersections of experiment and computation, and science and engineering. As a graduate student at the University of California, Berkeley, he developed and experimentally tested algorithms for designing protein molecules. As a postdoctoral researcher at The Rockefeller University, he developed several computational and experimental tools for better understanding how nervous systems generate behaviors.

Pokala and his colleagues have prototyped a diverse set of genetically-encoded light and chemical-activated tools for manipulating and perturbing the activity of individual C. elegans neurons. To comprehensively measure behaviors as they change over time, they have developed a software suite for tracking dozens of animals simultaneously for a spectrum of locomotion behaviors. They are using these tools to experimentally test algorithms for reverse-engineering the nervous system. The team’s goal is that the experimental methods and computational algorithms developed using C. elegans can be applied to more complex nervous systems, including, ultimately, human patients.
