Research Activities

Research in my laboratory is broadly aimed at investigating the determinants of drug-taking and drug-seeking behaviors. Accordingly, we utilize intravenous self-administration procedures to assess the degree to which factors such as age, diet, sex, and drug history influence (1) the acquisition of drug-taking, (2) the reinforcing effectiveness of drugs, and (3) the effectiveness of drug-associated stimuli to promote responding during periods in which the drug is no longer available. In addition to drug self-administration, we also utilize drug-discrimination procedures and radio-telemetric assessments of drug-induced changes in observable behavior, cardiovascular activity, body temperature, and locomotor activity in order to better characterize the pharmacologic profile of both drugs of abuse and candidate medications for the treatment of substance abuse.


Current research is focused on characterizing the abuse-related and toxic effects of synthetic cathinones (e.g., MDPV and methylone), an emerging class of abused drugs commonly referred to as “bath salts”. Through the use of quantitative approaches, these studies are also aimed at determining whether the discriminative stimulus, reinforcing and cardiovascular effects of synthetic cathinones are enhanced when they are administered in combination with another cathinone, or other common “bath salts” constituents.
