Research Interests

The lab focuses on different aspects of astrocyte-neuron interactions. In particular we study the effects of stress on astrocyte structure and function. We use an array of stress paradigms in an attempt to model different aspects of stress-disorders such as anxiety, PTSD, and depression. Our goal is to reveal how the effects of stress on astrocytes influences neuronal function and output, which in turn underlies behaviour.

We are also interested in the link between astrocyte metabolism and synaptic plasticity, investigating the specific conditions under which neurons rely upon astrocytes for energetic substrates, gliotransmitters, as well as clearance of neurotransmitters and metabolites. The lab has active collaborations to develop the next generation of tools to understand astrocyte metabolism.

We use complimentary techniques combining two-photon microscopy, electrophysiology, in vivo imaging, and behaviour.


Metabolic diseases, including obesity and diabetes, are major risk factors for the development of several chronic diseases, including cardiovascular diseases, and are the leading causes of mortality and morbidity in Western countries. The research components of this multidisciplinary axis foc…
