Dr. Karim Nader obtained his Ph.D. from the University of Toronto in 1996. Following his Postdoctoral studies at New York University, where  he worked under the supervision of Dr. Joseph LeDoux, he obtained his current position at McGill University. Since then he received numerous awards and honors including being selected for the “Canadian Top 40 under 40” in 2005, as well as part of Canada’s “Who’s who?” in 2010.


One of Dr. Nader’s most significant contributions is his demonstration that old memories can undergo protein synthesis-dependent re-storage. These findings challenged the dominant theory on memory consolidation. Further, the finding that memories can be stored more than once opened up a new dimension in the study of learning and memory at all levels of inquiry. This discovery presents a significant therapeutic potential in treating a variety of mental disorders, including post-traumatic stress disorder (PTSD), which result from uncontrollable intrusive memories. The possibility of reactivating a traumatic memory and preventing it from being re-stored has been recurrently discussed. In theory, such a treatment should provide an improvement in PTSD symptoms, and indeed we and others have shown that this treatment is feasible with patients.
