Andrei Popa received his B.A. in General Psychology from Alexandru Ioan Cuza University (Romania) in 2003 and he joined our lab in 2007. He received his M.A. in 2009 (field: computational behavior analysis) and entered candidacy in August 2011. His current research is focused on behavioral variability (impulsivity-like symptoms) as an emergent property of fixed organismic properties and specific environmental conditions. The overarching goal of this line of research is to use the Computational Theory to simulate behavioral interventions (melioration and large scale prevention) for high-level, emergent phenotypes, such as ADHD. He also teaches Abnormal Psychology and Theories of Personality at Georgia State University and the course on Evolution of Acquired Behavior at Emory University (Spring 2013).
