Research

Does stress bring us together, or does it drive us apart ?

I am investigating how stress, and its related biomarkers, influences our self-perceptions and how we interact with our social environment. To this end, I study the effects of stress on processes such as empathy, mentalizing, and prosocial helping behaviors. In addition, I am also studying how hormones like testosterone and oxytocin impact our ability to foster and maintain social relationships.

To understand these effects, I draw on various psychological disciplines - such as biological, social, and cognitive psychology.

In a second line of research, I study the effects of acute psychosocial stress on cognition. I am particularly interested in understanding how stress impacts cognitive process such as memory updating, separation of information, and autobiographical memories. To investigate these mechanisms, I collaborate with Dr. Signy Sheldon.

I am currently affiliated with the McGill Lab for Affiliation and Prosociality, the Pruessner Stress Lab, and the Sheldon Memory Lab.
