After finishing her postdoctoral work, Josselyn moved back to Toronto to start her lab at SickKids Hospital at the University of Toronto.[1] Her overall goal is to understand how humans learn and remember such that one day her work can impact translational research at her institute and in her community.[3] Some of Josselyn's early discoveries include discovering that CREB over-expression in the auditory thalamus increases memory and fear,[12] and further, that ablating neurons that highly expressed CREB after fear learning actually ablates fear memories in rodent.[13] These were some of the first findings isolating specific neurons representing a specific memory in the brain.[13] Josselyn's multidisciplinary approach to tackling questions regarding memories led her to several prestigious awards and recognitions including becoming a member of the Royal Society of Canada in 2018 for her research.[14]
