How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

PROGRAM AREAS: Behavioral Neuroscience and Psychopharmacology TEACHING INTEREST: Learning and Learning Laboratory, Psychopharmacology, Hormones and Behavior, Drugs and Behavior, Sensation and Perception, Research Methods RESEARCH INTEREST: Learning, motivation, and the involvement of hormones in the development and maintenance of drug addiction-like behaviors. Specifically, the investigation of potential behavioral and pharmacological treatments for drug addiction-like behaviors.
Addiction is characterized as a chronic debilitating disease. One devastating feature of addiction is the susceptibility of relapse (40–60%) after stretches of abstinence. One theory that may account for relapse suggests that drug cues (e.g., paraphernalia) may increase stress hormones, and this may prompt relapse. Repeatedly pairing a neutral cue...
A devastating feature of drug dependence is the susceptibility of relapse (40-60%) after stretches of abstinence. In both animal and human research, it has been demonstrated that cues (e.g., levers, paraphernalia) associated with drug reward can instigate renewed drug taking. Research has shown animals that attend to a cue that predicts reward more...
Relapse-like behaviors have been measured in animals using the Pavlovian conditioned approach (PCA) model. During conditioning, a reward is paired with a novel, neutral cue (unconditioned stimulus; UCS). Repeated pairing of the UCS with a salient reward can elicit a conditioned response (CR). Sign tracking (STing) is a CR to the newly conditioned s...
The pandemic of 2020 forced many instructors to reevaluate their teaching and assessment practices. Assignments and assessments designed for face-to-face classes were quickly adapted to go online. Faculty-to-student relationships built through classroom interactions were transformed by the mediation of online platforms. At the time, the co-authors...
Background: Cocaine is the number one abused psychostimulant drug that reaches addiction criterion in the US. In animals, repeated administration of cocaine results in behavioral sensitization which is thought to represent adaptations in the mesolimbic dopamine neural circuitry, the reward pathway. Cocaine-induced behavioral sensitization is evide...
