We use a multi-disciplinary approach to understand the neuronal mechanisms of fear and anxiety behaviours Our goal is to learn how experiences modify neuronal circuit physiology to form memories
and how these functional alterations oppose or promote flexible emotional behaviour. To identify the neuronal mechanisms of fear and anxiety states
our lab uses multiple techniques to record time-series neuronal activity during fear and anxiety behaviours. We aim to understand the neuronal circuit motifs that support fear and anxiety behaviors
with the hope that our circuit models may inform novel therapeutics to treat individuals living with mental illness. • Ability to work independently and efficiently. • Strong organizational and task prioritization skills. • Excellent communication skills and proficiency in performing administrative and clerical tasks. • Proficient in general laboratory procedures

and molecular analysis. Research overview Threatening or dangerous situations create a constellation of physiological and behavioural responses. Yet
how an organism responds to a threatening situation depends on a variety of factors such as age
biological sex
past experiences
and the present spatial context. We are particularly interested in how hippocampal context/spatial representations in the brain are modified by these experiential factors to guide evolutionarily conserved emotional behaviour. Our lab specifically investigates the dynamic circuit mechanisms that generate flexible fear and anxiety states. We use multiple state-of-the-art techniques to understand how fear and anxiety are represented in the brain and define the neuronal circuits responsible for these defensive behaviours. By resolving the neuronal circuits that support defensive behaviours
our hope is for our discoveries to lead to novel therapeutics that reduce symptoms of mental illnesses such as post-traumatic stress disorder
generalized anxiety disorder
and depression.
