Barbara Bayer, Ph.D.
Georgetown University

Chair and Professor in the Department of Neuroscience and Senior Associate Dean of Biomedical Graduate Education.

Chronic use of addictive drugs has been shown to produce alterations in several genes and protein expression in select areas of the brain.  These changes may contribute to the development of addiction and the prolonged susceptibility to stress-induced drug seeking behaviors.  Over several decades, Dr. Barbara Bayer’s NIH funded research has focused on the effects of exposure to stress and centrally acting drugs of abuse on the immune system.  Her research identified specific sites and neurotransmitter systems in the brain that were involved in the regulation of immune cell activity.  These effects were found to be accompanied by the alteration of unique gene expression patterns in blood lymphocytes that may prove to be important biomarkers of CNS induced alterations in gene and protein expression.  If so, these changes may be used to identify specific biomarkers of addiction and may ultimately reveal biological targets for improved therapeutic strategies to treat addiction.

In addition to her research, Dr. Bayer has been involved in graduate education for over 30 years as mentor of PhD students.   She has mentored many PhD students in both Pharmacology and Neuroscience and was awarded a PhD training grant from National Institute for Drug Abuse (NIDA) for 15 years.  In addition, the majority of students in her laboratory were also awarded individual NRSA fellowships from NIDA for their thesis research projects.  Dr. Bayer has been the recipient of several teaching awards including the Excellence in Graduate Training Award, the Kaiser-Permanente Award for Excellence in Basic Science Teaching and she was inducted into the MAGIS Society of Master Teachers.   Over the past 8 years Dr. Bayer has served as the Senior Associate Dean of Biomedical Sciences at Georgetown University and has been involved in PhD and Masters graduate student training to provide both the necessary resources and educational environment for their successful careers in the biomedical sciences. 

Kathleen Maguire-Zeiss, Ph.D.
Fundamentals of Neuroscience

Dr. Maguire-Zeiss is a Professor and Department Chair of the Department of Neuroscience at Georgetown University. Dr. Maguire-Zeiss’ laboratory aims to understand the molecular mechanisms involved in progressive neurodegenerative diseases like Parkinson’s disease and HAND. The laboratory focuses on glial-directed innate immune responses and the effect of inflammation on neuronal health and function.  By investigating how glial cells respond to chemokines/cytokines and misfolded proteins, specific signaling pathways are identified and novel therapeutics are subsequently identified and tested.  For example, the Maguire-Zeiss lab demonstrated that the Parkinson’s disease relevant protein, misfolded alpha-synuclein,  increases oxidative stress and alters neuronal membrane conductance.  This group also demonstrated that this pathologic protein directly interacts with toll-like receptors on microglia inciting a proinflammatory response in these cells.  Importantly, toll-like receptor antagonists attenuate this inflammatory response. Using primary cultures, acute brain slices, and mouse models the Maguire-Zeiss lab is helping to decipher the molecular events important for the pathogenesis of disorders like Parkinson’s disease and HAND in an effort to discover novel therapeutic approaches for these debilitating diseases.

Lucile Adams-Campbell, Ph.D.
Georgetown University and Georgetown University Medical Center

Associate Director for Minority Health and Health Disparities Research, Senior Associate Dean for Community Outreach and Engagement, and Professor of Oncology at Lombardi Comprehensive Cancer Center at Georgetown University Medical Center. She is also the Program Director of the Master’s in Epidemiology Program, Graduate School of Arts and Sciences at Georgetown University.

Dr. Adams-Campbell’s areas of research focus on addressing health disparities with particular emphasis on cancers that disproportionately impact African-Americans. Her research focuses on lifestyle interventions including physical activity, energy balance, obesity, metabolic syndrome, and oral health among minority and underserved populations. She has considerable expertise in cohort studies including the Women’s Health Initiative and the Black Women’s Health Study (which follows a cohort of African American women to gather epidemiological data on health risks and disease development). She has more than 200 peer reviewed publications.

Dr. Adams-Campbell has received numerous awards and honors including the election to the National Academy of Medicine, and the Induction into the D.C. Hall of Fame for her research focus on Health Disparities as well as gold medallions awarded from both of her alma maters – the University of Pittsburgh and Drexel University – for outstanding contributions to the field of public health and health sciences. Dr. Adams-Campbell earned her B.S. in Biology and a M.S. in Biomedical Science from Drexel University in Philadelphia, PA, and received her Ph.D. in Epidemiology from the Graduate School of Public Health at the University of Pittsburgh.
