My interest in neuroscience began as an undergraduate here at Brown, where I worked in visual cortical synaptic plasticity in the laboratory of Mark Bear. As a PhD student in Johns Hopkins with David Linden, I studied plasticity of inhibitory inputs and of intrinsic excitability of deep-cerebellar nuclear neurons. My postdoctoral work was done in the lab of Holly Cline, where I combined my interest in the visual system with my interest in the regulation of neural excitability, work which continues in my current lab. I have been at Brown since summer 2004.

The long-term goal of my research is to understand the role of sensory experience in shaping the connectivity and functional properties of developing neural circuits, as well as it's implications for neurodevelopmental disorders. We focus on the visual system of Xenopus laevis tadpoles; a preparation amenable to a variety of experimental approaches, ranging from molecular biology, single-cell electrophysiology, live cell imaging, computational modeling, and behavior.
