I graduated with a PhD in Pharmacology from University College London in 1986 and then studied with Richard W Tsien as a postdoctoral associate at Yale University School of Medicine and subsequently at Stanford University Medical School. In 1992 I joined the Department of Neuroscience at Brown. I study the expression, regulation, and function of voltage-gated calcium ion channels in different regions of the nervous system. I am also interested in their role in chronic pain and psychiatric disorders. I work closely with undergraduate and graduate students, as well as postdoctoral trainees. I direct the Brown Institute for Brain Science and Direct NIH funded Predoctoral Training Programs in Neuroscience.

My laboratory studies neocortical dynamics, changes in activity that occur on millisecond to second time scales. We seek to understand the meaning of these dynamics for perception, and the mechanisms that generate them. We are currently testing hypotheses as to the computational value and origins of neocortical oscillations, and the role that non-neuronal systems (e.g., the vasculature) may play in information processing. To address these questions, we integrate behavior, optogenetics, electrophysiology and imaging.

Justine leads efforts to execute the innovation, dissemination, and education goals of the Hub. She provides scientific direction and maintenance of the Hub's website and database, coordinates the activities of program workshops, symposia, and emissaries, and develops curricula for education outreach activities at the elementary, high school, undergraduate, and graduate levels.
