I’m a neuroscientist. I study how the nervous system controls movement—a major challenge in neuroscience with implications for treating movement disorders, designing neural prostheses, and robotics.
I tackle this challenge in the fruit fly, Drosophila. The unparalleled genetic tools and the compact nervous system of this model organism enable us to develop a detailed, mechanistic understanding of movement control.
Research
Much like us, flies coordinate their limbs via intricate neural circuits in their “spinal cord.” I study how these circuits are organized, how they operate in behaving animals, and how they integrate movement instructions from the brain with sensory feedback from the legs. To that end, I combine motion capture, optogenetics, and calcium imaging of neural activity in behaving animals with comprehensive connectivity analyses (connectomics).
As a graduate student, I studied motor control from a biomechanics perspective. I combined motion capture, force measurements, and electromyography in freely walking stick insects—another invertebrate model organism (check out The New York Times ScienceTake).
