Joseph Troisi, Ph.D.

1990-1992 - Post-Doctoral Fellow Behavioral Pharmacology, Johns Hopkins University School of Medicine
1990 - Ph.D., Experimental Psychology, Temple University
1984 - B.A., Psychology, Temple University

Professor Troisi's translational research in behavioral pharmacology investigates extinction of motivated voluntary behavior (and the interaction with involuntary behavior) under nicotine, alcohol, and recently caffeine, to simulate how other internal states (stress, hunger, thirst, emotions, craving and other drug effects) play roles in relapse behavior and its inhibition (i.e., treatment). His current work concerns conditioning factors with drug mixtures and how environmental stimuli modulate such internal stimulus effects during extinction and relapse-like phenomena. Professor Troisi recently completed an NIH (NH-INBRE) grant that addressed some of these issues.

He taught previously as an instructor and as a graduate/teaching assistant during his graduate training in Experimental Psychology at Temple University. There, his research focused on endogenous opioid mediation and Pavlovian conditioning factors of Learned Helplessness (a model of human depression). His Ph.D. dissertation thesis assessed hierarchical control of stimuli in Pavlovian facilitation and occasion-setting, which he has been applying to the study of operant (voluntary behavior) drug discrimination.

Prior to arriving at Saint Anselm College, Professor Troisi completed a two-year Post-Doctoral fellowship training program in human behavioral pharmacology/substance abuse at the Behavioral Pharmacology Research Unit (BPRU) at Johns Hopkins University School of Medicine where he worked with recreational drug abusers and studied human drug discrimination and drug abuse liability assessment of sedative/hypnotic drugs.

His general research interests are rooted in, Behavioral Analysis, associative learning and Pavlovian/operant interaction. Professor Troisi's current research interests in behavioral pharmacology include Pavlovian and operant processes in drug discrimination. Other work in this area includes the impact of environmental influences on drug tolerance, and drug discrimination.

Over the years, Professor Troisi has collaborated with colleagues at Kings College London England, Exeter University UK, University of Kentucky, Northeastern University Center for Drug Discovery, and has recently established connections for potential projects with colleagues at TUFTS University Veterinary School. He has served as an invited reviewer for several peer-reviewed journals in animal learning and behavioral pharmacology.
