Dr. Fahnestock began her research program in neurotrophin molecular biology during her first appointment, at SRI International (formerly Stanford Research Institute), in 1984. Following a sabbatical in the Department of Neurology at the University of California at San Francisco, Dr. Fahnestock moved to the Department of Biomedical Sciences at McMaster University in September, 1991. She joined McMaster’s Department of Psychiatry and Behavioural Neurosciences in 1998 and was promoted to Full Professor in 2003. She has published more than 100 peer-reviewed journal articles and book chapters and has been continuously funded during the past 30 years by CIHR, NIH and private foundations. Dr. Fahnestock is a three-times past President of the Southern Ontario Neuroscience Association and is a member of CCNA (Canadian Neurodegenerative Diseases Consortium) and ART (Canadian Autism Research and Training Program). At McMaster, she is an Associate Member of the Department of Biology, was founding Associate Director of the MiNDS Neuroscience Graduate Program and is a member of MOBIX and MacART. She is regularly invited to speak at international meetings and seminar series on the role of neurotrophins in neurological disorders.
