Karim Nader is an associate professor in the Department of Psychology at the McGill University in Montreal, Canada, where he holds a Willam Dawson Chair.
Nader works on how recent memories are transformed into long-term memories, by a process called memory consolidation. When we recall a memory, that memory becomes unstable; and when a memory becomes unstable, it can be modified. According to him, by interfering with protein synthesis, an important molecular process in memory consolidation, a memory can be modified or "tuned down".
His research group specializes now in memory and trauma. Their research has focused on victims of post-traumatic stress disorder, which can force them to relive their ordeals. Dr. Nader's experiments suggest that damaging memories can be stripped of their potency by a common blood pressure medication, propranolol.
Headlines around the world about this research have often been considered inspirational to the fictional Eternal Sunshine of the Spotless Mind.
Together with biologist Andrew P. Hendry, they were nominated the 2009 recipients of the prestigious E.W.R. Steacie Memorial Fellowships. Nader is also an Alfred P. Sloane Fellow, a recipient of a CIHR New Investigator Award, and has been named one of the "Top 40 under 40" in 2006.
Nader published his essay Memories are Constructive in Nature in V2_'s 2004 Feelings Are Always Local.
