Research. ​​I am interested in the neuronal control of homeostatic and hedonic feeding behaviours and the modulation of these circuits by environmental factors that alter behaviour. I am currently investigating how cannabis stimulates food intake (a phenomenon commonly known as ‘the munchies’) with the aim of deciphering the neuronal mechanisms that underlie these cannabis-induced motivated feeding behaviours. This research involves the use of specialized cannabis vapor administration chambers combined with various behavioural paradigms (including operant conditioning), as well as pharmacological and circuit-based manipulations.​
​Hobbies. ​​I like to cook, pet dogs, watch true crime documentaries and drink margaritas :) ​​
Favourite paper. ​​​​‘AGRP neurons are sufficient to orchestrate feeding behavior rapidly and without training’ (Aponte et al 2011 Nat Neurosci; PubMed link). This paper has a special place in my heart as after reading it, I decided to carry out a PhD in feeding behaviour research. It is an exceptional study showing for the first time that feeding behaviours can be driven by the specific activation of a single hypothalamic circuit.

education
After completing my BSc in pharmacology, I remained at the University of Edinburgh (UK) to carry out my PhD in the Centre for Integrative Physiology with Professor Gareth Leng and Dr John Menzies. I investigated how the homeostatic energy balance system compensates for the hedonic consumption of palatable, high-sugar food to maintain body weight.
Following a short postdoc in the lab of Professor Mike Ludwig (Centre of Discovery Brain Sciences, University of Edinburgh (UK)) investigating how retinal vasopressin regulates hypothalamic circuits controlling circadian rhythms, I moved to Dr. Matthew Hill’s lab at the University of Calgary to continue pursuing feeding behaviour-based research.
Research funded by Brain Canada, BONF, CFI, CIHR, NIH and NSERC. Many thanks to the University of Calgary Cumming School of Medicine, Hotchkiss Brain Institute, Mathison Centre, and Alberta Children's Hospital for their support.
