Dr. Franck Polleux – Ph.D.

Professor of Neuroscience


Dr. Franck Polleux did his undergraduate and graduate studies at Université Claude Bernard in Lyon, (France) where he obtained his Ph.D. in Neuroscience in 1997. He then joined the laboratory of Dr. Anirvan Ghosh at Johns Hopkins University for his post-doctoral training. In 2002, Dr Polleux was hired as an Assistant Professor in the Neuroscience Center and Department of Pharmacology at the University of North Carolina- Chapel Hill where he became an Associate Professor in 2008. In August 2010, he joined The Scripps Research Institute in La Jolla, California.

In November 2013, he was recruited as a Professor in the Department of Neuroscience at Columbia University to join the new Mortimer B. Zuckerman Mind, Brain, Behavior Institute.

Throughout his career, Dr Polleux has focused on the identification of the molecular mechanisms underlying neuronal development in the mammalian brain. More recently, his lab started studying the genetic basis of human brain evolution as well as the signaling pathways underlying synaptic loss during early stages of Alzheimer’s Disease progression.

2016_2_16_justin_headshot-25Justin O’Hare, Ph.D.

Justin carried out his graduate work in the lab of Nicole Calakos at Duke University Medical Center. He joined the Polleux lab in 2017 where he studies how the endoplasmic reticulum (ER) and mitochondria networks regulate spatiotemporal dynamics of dendritic calcium in the context of synaptic integration, plasticity, circuit function and behavior.
