Research Interests

My research is the area of protein-based medications, specifically anti-stimulant (methamphetamine and synthetic cathinone) monoclonal antibodies and vaccines. These novel biologics are promising for the treatments of medical problems caused by drugs of abuse. These are needed due to the limited efficacy of small molecule drug therapies for stimulant abuse. I am a member of a team of scientists under the leadership of Dr. Michael Owens in the Department of Pharmacology and Toxicology in the College of Medicine. This multidisciplinary team has been studying antibody-based treatments for drugs of abuse since the 1980’s. My particular interest involves developing new analytical methods (behavior, pharmacokinetics, cell culture, etc.) to test the efficacy of these monoclonal antibodies. In addition, I am interested in discovering combination therapies that can potentially increase the anti-drug effects relative to monotherapy.
