Dr. Katrina Choe is an Assistant Professor in the Department of Psychology, Neuroscience & Behaviour at McMaster University.

After obtaining her bachelor’s degree (University of Toronto), Dr. Choe completed her doctoral thesis on the hydration state-dependent control of vasopressin neuron excitability using in vitro electrophysiological techniques (Charles Bourque lab, McGill University). In her first postdoctoral position (Thomas Otis lab, UCLA), Dr. Choe mapped functional circuits that mediate cerebellum-to-forebrain communication using a combination of optogenetics, in vivo electrophysiology, and mouse fMRI. In her second and final postdoctoral position (Daniel Geschwind lab, UCLA), Dr. Choe identified a potential mechanistic link between gene mutations, the central oxytocin system, and social deficits in the Cntnap2 knockout mouse model of autism spectrum disorders (ASD) using mouse fMRI, lightsheet imaging, behavioural assays, and RNA-seq.

In her newly established laboratory at McMaster University, Dr. Choe will apply a multi-level, integrative research strategy to link how gene mutations associated with psychiatric disorders disrupt social behaviour. She has published 13 papers in various journals including Neuron, NeuroImage and the Journal of Neuroscience. Her research has been supported by national awards from the Canadian Institutes of Health Research (CIHR) and National Institute of Mental Health (NIMH).

When away from the lab, Dr. Choe enjoys travelling, hiking, snowboarding, trying out new cuisines and watching nature documentaries.
