Karim Nader is a professor at McGill University in the department of Psychology. As a neuroscientist he works to understand what neurobiological processes are involved in acquiring and storing memories, especially relating to fear, in order to use the study of memory reconsolidation to treat anxiety disorders. Dr. Nader made a breakthrough in the field in 1999, when he first revived and tested the obscure theory that memories do not necessarily remain stable--think Eternal Sunshine of the Spotless Mind. Together with Andrew P. Hendry, Dr. Nader was nominated in 2009 for the prestigious E.W.R Steacie Memorial Fellowship. He is also the recipient of a CIHR New Investigator Award and in 2006 was named one of the Top 40 under 40.
