Nayani Ramakrishnan, PhD, Research Associate , University of Toronto

I currently work as a Research Associate for Dr. Suzanne Erb. Prior to this role, my PhD work aimed to understand the psychological processes governing human behaviour in response to childhood adversity. In particular, I developed a conceptual model to elucidate the relationship between childhood adversity and substance use problems in emerging adults by examining factors such as emotion dysregulation, reward processes, and impulsivity. Outside of the lab, my hobbies include photography and interior/graphic design.

Co-supervised by Dr. Suzanne Erb and Dr. Marc Fournier, my research primarily focuses on impulsive behaviors and understanding the conditions under which impulsivity might be advantageous. Currently, I am developing a momentary measure for impulsivity and investigating situational contingencies that influence state impulsive actions. A key objective of my work is to uncover the underlying reasons for discrepancies between self-reported and behavioral measures of impulsivity. Outside the lab, I enjoy baking, poetry, reading, knitting, and crocheting.


Cindy Tao, PhD Candidate, MSc, BSc (Hons), Queen’s University

My research examines the complex relationships between acute stress and sex on reward processing using both behavioural and neurobiological methods. I aim to reconcile previous disparate findings by using a consistent study design across various stressor types in order to assess the different facets of reward processing. Outside of the lab, my hobbies include baking, hiking, and art history.
