Dr. Michael W. Best

Dr. Best is a clinical psychologist and Assistant Professor in the Departments of Psychology and Psychological Clinical Science at the University of Toronto Scarborough and is an Affiliate Scientist at Ontario Shores Centre for Mental Health Sciences. Dr. Best completed his Ph.D. in Clinical Psychology at Queen’s University and his predoctoral internship at the Aaron T. Beck Center for Recovery-Oriented Cognitive Therapy at the University of Pennsylvania.


His research focuses on cognitive treatments for psychotic disorders and understanding the mechanisms for how these treatments improve people’s lives. Cognitive Behavioural Therapy (CBT) is an evidence-based therapy that focuses on how thoughts, emotions, and behaviours are interconnected and contribute to a person’s quality of life. Cognitive Remediation is a treatment to improve neurocognitive abilities such as attention, memory, and problem-solving with the ultimate goal of improving a person’s ability to engage in activities in everyday life.

Robert Aidelbaum

Rob is a doctoral student in the Clinical Psychology program at the University of Toronto Scarborough. He completed an MA in Clinical Psychology at the University of Toronto and an MA in Experimental Psychology at Carleton University.


Rob’s research interests involve analyzing the manifestation of both neurocognition and social cognition in various diagnostic groups across the psychosis spectrum and assessing how patterns of impairment may be influencing real-world functioning. The goal of his research is to improve our understanding of the connection between cognition and functioning, in the hopes of supporting the development of novel treatments aimed at improving areas causing lasting distress that do not respond to current standard treatments.  

When not in the lab, you will likely find Rob either camping, skiing, working in his garden, watching a movie, or playing with his dog.

Jess D'Arcey

Jess is a first-year MA student in the Clinical Psychology program at the University of Toronto, Scarborough. She completed her BSc in Mental Health Studies at UTSC as well as an MSc in Medical Science at the University of Toronto and CAMH.

More specifically, Jess is interested in cognitive and emotional models of symptom maintenance in hopes of highlighting new treatment targets and finding ways to adapt current treatments. She hopes to center lived experience in her work.


Outside of psychology, Jess enjoys spending her time outside in nature with her pup, camping, crafting,  spending time with friends, or curled up with her cat and a good book! 

Aqsa Zahid


Aqsa is a graduate student in the Counselling and Clinical Psychology program (Field: Clinical Psychology) at the University of Toronto Scarborough. She completed her undergraduate degree at the same university where she specialized in Mental Health Studies.


Aqsa is primarily interested in studying stigma among and towards individuals with schizophrenia-spectrum disorders. She hopes to include the examination of various forms of stigma in her research (e.g., internalized, public, provider/professional, and institutional stigma). She plans to apply an intersectional approach to her research to understand how social identities such as race and gender (in addition to one’s diagnostic label or symptom presentations) may ultimately result in unique experiences of stigma, discrimination, and barriers among diagnosed persons. Secondarily, Aqsa has a growing interest in exploring religious and cultural understandings of schizophrenia and other mental disorders.


Apart from her studies, Aqsa really enjoys painting, exercising, cooking, and spending time with her cat. An ideal weekend for her would include all of these activities with the addition of unlimited coffee!
