Lab Manager

Maric’s research interests include the neurobiology of addiction and schizophrenia. He mainly uses electrophysiology and behavioural approach to study various models of the disorders. Maric first became interested in dopamine-related disorders while studying neurobiology of motivation and sex in the laboratory with Dr. Jim Pfaus (Concordia University). Under the guidance of Dr. Stan Floresco, Maric expanded his training on the role of dopamine in the cognitive system. Outside of the lab, Maric enjoys any water sport that involves the ocean.

Research Associate

Gemma Dalton is originally from a small town in rural Ireland, receiving her BSc from Queen’s University of Belfast, MSc from the National University of Ireland, Galway, and PhD from the University of Sussex. She works as a research associate with Dr. Anthony Phillips and has been working on a number of collaborative projects with the Floresco lab. Gemma has been here so much that the lab has graciously given her an office and most members of the lab actually think she is in the Floresco lab full time. Her work uses cognitive assays developed in the Floresco Lab to investigate the potential antipsychotic efficacy of some novel compounds that may change neuroscience as we know it. She is super happily married to an awesome guy who hails from Vancouver. Together they have a 5 year old daughter who has inherited every bit of her father’s unreserved sociability and tenacity.

Graduate Student

Nicole is a PhD candidate in the Behavioural Neurosciece program. She completed both her BSc and MA in Pyschology at UBC.  Nicole’s research focuses on characterizing cortico-striatal and amygdalar circuits that control different aspects of  appetitvely motivated behaviours, from simple reward learning to more complex forms of decision-making such as decisions related to reward uncertainty, or risk.

Graduate Student

Debra (she/her) is a PhD Candidate in Behavioural Neuroscience. Her research focuses on using pharmacological and optogenetic approaches to study how neural activity in the medial prefrontal cortex is important for behavioural flexibility. Debra is a Singaporean-Canadian from Montreal, where she completed her BSc at McGill University working with Dr. Jonathan Britt.

Graduate Student

Jackson is originally from Columbus Ohio and completed his BS in neuroscience at The Ohio State University. At OSU, he worked with John Bruno investigating how embryonic and adolescent exposure to heightened levels of the endogenous metabolite kynurenic acid resulted in schizophrenia-like cognitive and neurochemical deficits in adulthood. His masters project will focus on the role of dopamine in the PFC in mediating cue-guided cost/benefit decision making.


Valerie completed her B.A. in Psychology at UBC in 2020. During her undergraduate degree, Valerie worked in the Floresco lab studying the role of the medial prefrontal cortex in behavioural flexibility. As a M.A. student, she is currently co supervised by Dr. Kiran Soma, and her research focuses on investigating the relationship between locally-produced testosterone in the mesocorticolimbic system and behavioural flexibility, specifically looking at the effects of testosterone and its sites of action.

Giulio was born and raised in Rome, where he picked up all of his quirks on food and un-solicited puns. He pursued his Bachelor’s degree at UBC in neurobiology and physiology and worked on his honours thesis with Dr Catharine Rankin on Parkinson’s Disease genetics using the C. elegans model system. Now he is in the Floresco lab as a Master’s student in the Neuroscience program investigating the effects of stress/corticotropin-releasing hormone in rats on the meso-cortico-limbic dopamine circuitry responsible for decision-making.
