Amy is a PhD student in Clinical Psychology at McGill University Her research focuses on identifying situational factors and individual differences that impair demonstrated empathic accuracy. She is also interested in the relational consequences of fluctuations in empathic accuracy and cognitive empathy, which a specific interest in support provision.




Willis is a PhD student in Experimental Psychology at McGill University. He is interested in the epistemic function of close relationships. His research focuses on better understanding the psychological consequences of gaslighting and how to recover from epistemic abuse. He is also interested in how close relationships alter the self-concept.  Willis holds a BSc in Psychology and Cognitive Science from the University of Toronto.

Kristina is a former SSHRC and HBHL fellow who completed her PhD in Experimental Psychology at McGill University. She is currently a postdoctoral researcher at the McGill Laboratory of Affiliation and Prosociality. Her research examines the neurobiological mechanisms that contribute to the formation and maintenance of social bonds, as well as the influence these mechanisms exert on emotional and physical health.

Past Graduate Students & Postdoctoral Fellows


Dr. Gentiana Sadikaj completed her Ph.D. in Clinical Psychology at McGill University in 2012. She completed her postdoctoral fellowship under Dr. Bartz's supervision in 2017, and she is currently an assistant professor at Concordia University. Broadly speaking, Genta is interested in understanding (1) person and situational influences on personality processes involving perception of others, affect, and interpersonal behavior, (2) intrapersonal and interpersonal consequences of personality processes, and (3) perception accuracy. Presently, she is examining whether specific polymorphisms in the oxytocin receptor gene (OXTR) influence interpersonal dynamics between romantic partners in naturally occurring interpersonal situations. 


Dr. Sonia Krol completed her PhD student in Clinical Psychology at McGill University under the supervision of Dr. Bartz. She also completed her BA in Psychology at McGill University. Broadly, Sonia is interested in the relationship between the self and social behaviour. Specifically, she studies how one’s sense of self—the extent to which one knows who they are—influences self-other distinction, particularly in the context of empathy.

Cecile completed her M.Sc. at McGill University under the supervision of Dr. Bartz investigating the neurobiological and social cognitive underpinnings of human affiliation and prosociality. Cici is completing her PhD in Clinical Psychology at Southern Methodist University under the supervision of Dr. Benjamin A. Tabak where she aims to continue exploring the psychological and neurobiological mechanisms which support our ability to connect with others.



Jonas completed his PhD in Experimental Psychology at McGill University under the supervision of Dr. Bartz. Jonas is completing his post doctoral research in the Social, Cognitive and Affective Neuroscience Unit at University of Vienna under the supervision of Dr. Claus Lamm. He is interested in how stress influences our self-perceptions and how we interact with our social environment.
