Research Interests

Dr. Andrea Hobkirk is an affiliate of Penn State Tobacco Center of Regulatory Science (TCORS), co-funded by the National Institutes of Health and the Food and Drug Administration. TCORS evaluates the potential for new tobacco products, such as reduced nicotine content cigarettes, to reduce harm to the public. In collaboration with TCORS, Dr. Hobkirk uses neuroimaging and biobehavioral methods to investigate the development and maintenance of tobacco dependence and nicotine addiction. Her work aims to reduce health disparities among socially and economically disadvantaged populations. She is currently an institutionally supported KL2 scholar associated with the National Center for Advancing Translational Sciences.

During her postdoctoral training at Duke University, Dr. Hobkirk received a fellowship from Duke Global Health Institute, a National Research Service Award from the National Institute on Drug Abuse, and a Scholar Award from Mount Sinai Institute for NeuroAIDS Disparities.
