Dr Guillermo Perez Algorta

Lecturer

Research Overview

I received my Ph.D. in psychology from Palermo University, Buenos Aires, Argentina. During 2012 - 2014, I was a Post-Doctoral Researcher in the Child Mood Disorders Lab, at the Ohio State University. Since 2011, I am an Adjunct Assistant Professor of Psychology, at the University of North Carolina at Chapel Hill. My research interests include phenomenology, evidence based assessment and treatment of bipolar spectrum disorders. I opened a research stream at Lancaster about circadian dysregulation’s impact on sleep and mood symptoms. Also, I am interested on aggressive and self-destructive behaviours, and externalizing disorders (ADHD).
