Jacqueline Keighron earned her Ph.D. in chemistry at Penn State University in the laboratory of Dr. Christine Keating, where she studied the interactions of enzymes with nanostructured materials. Her dissertation focused on the creation and characterization of enzyme-nanoparticle bioconjugates as model systems for the multi-enzyme complexes that exist in biological cells.
Following graduate school, Keighron conducted her postdoctoral research in the laboratories of Drs. Andrew Ewing and Ann-Sofie Cans at Chalmers University of Technology in Gothenburg, Sweden. In the Ewing lab, Kreighron studied dopamine dynamics in vivo and in vitro, employing a variety of analytical techniques. In the Cans lab, she helped develop ultra-fast electrochemical methods for detecting non-electroactive neurotransmitters, including acetylcholine and glutamate.
Upon returning to the U.S., Keighron was awarded a fellowship at the National Institute on Drug Abuse in Baltimore, Md., as part of the Medications Development Program under the leadership of Drs. Amy Newman and Gianluigi Tanda. There, she studied the effects of psychostimulants of abuse on dopamine dynamics and the neurochemistry of potential treatments for psychostimulant abuse.
- Keighron's current research interests include using ultrafast and multianalyte biosensors to study the dynamics of glutamate and dopamine in vivo, as well as the neurochemical effects of drug molecules that have both therapeutic and abusive properties.
