Degrees
Harvard University, Ph.D.Cornell University, B.A.
Expertise
Research in my laboratory seeks to define the genes that instruct neurons to establish and modify their connectivity, with the overall goal of understanding how neural network dysfunction contributes to neurological disorders. We currently employ biochemistry, molecular biology, genetic, computational modeling, and imaging approaches both in vitro and in vivo to elucidate the molecular mechanisms of synapse formation and circuit connectivity.Profile
Dr. Paradis received her BA from Cornell University and her PhD in Genetics from Harvard Medical School. Her thesis research, performed in the laboratory of Dr. Gary Ruvkun, investigated the genetic program that regulates lifespan in the nematode C. elegans. During her postdoctoral fellowship in the lab of Dr. Michael Greenberg at Harvard Medical School, she identified new molecules required for synapse formation. Her own lab at Brandeis University focuses on how intact circuits form in the mammalian CNS by defining the genes that instruct neurons to modify their synaptic connections and dendritic morphology in response to changes in sensory experience. Dr. Paradis has been the recipient of numerous awards including the Society for Neuroscience Career Development Award in 2007 and Alfred P. Sloan Research Fellowship in 2009.Courses Taught
