Wayne D. Bowen, Ph.D.
Wayne Bowen is a nationally recognized leader in research on sigma receptors—proteins in the brain and in tissues like the liver and kidney that are believed to regulate cell survival and growth. His major areas of interest include biochemical mechanisms involved in the neuronal action of opiate drugs, and the biochemistry of sigma receptors in cancer cells and in the brain.
Bowen received his B.S. in chemistry from Morgan State College in 1974, and completed his Ph.D. in biochemistry and neurobiology at Cornell University in 1981. He then spent three years as a postdoctoral staff fellow at the National Institute of Mental Health in Bethesda, Maryland, where he studied opiate receptor biochemistry. He initially came to Brown University in 1983 when he taught endocrinology, introductory biology and biochemistry and founded the macromolecular biochemistry facility—a one-man lab that supplied synthetic peptides to scientists throughout the campus and affiliated hospitals.
In 1991, Bowen returned to the NIH to take a position at the National Institute of Diabetes and Digestive and Kidney Diseases, where he became chief of the unit on receptor biochemistry and pharmacology in the drug design and synthesis section of the Laboratory of Medicinal Chemistry. He also served as president of the NIH Black Scientists Association in 2001.
In 2004, Bowen returned permanently to the Brown faculty as professor of biology in the department of molecular pharmacology, physiology and biotechnology in the Division of Biology and Medicine. He co-directs the medical school's pharmacology course and teaches in the endocrinology and neuroscience courses to undergraduates.

Malcolm V. Brock, M.D.
Malcolm V. Brock, M.D., a graduate of the Johns Hopkins University School of Medicine, the Johns Hopkins General Surgical residency program and the Johns Hopkins fellowship in cardiothoracic surgery, is a specialist in thoracic oncology, and is an associate professor of surgery and oncology at Johns Hopkins. In additional to clinical thoracic oncology, his clinical interests include surgery for palmar, axillary and pedal hyperhydrosis.
Board-certified in general as well as thoracic surgery, Dr. Brock is a surgeon who conducts cancer research at the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins specializing in bringing innovative basic, bench-top research to the clinic and to the bedside. His main research interests are in developing novel molecular biomarkers for solid tumors that can help clinicians diagnose cancer earlier and treat it more effectively. Recently, his laboratory utilized a basic research DNA technique in the clinic to predict patients who will develop recurrent lung cancer even after successful surgery, and to predict patients with esophageal cancer who will be sensitive to certain chemotherapeutic drugs. This work was recently recognized for publication in the New England Journal of Medicine. Dr. Brock has published over 70 original research papers, book chapters and review articles, has presented often at national and international conferences, and has been the recipient of research funding from the National Institutes of Health (NIH), the Thoracic Surgery Foundation for Research Excellence, the American College of Surgery Oncology Group as well as the Society of Surgical Oncology.

Chanita Hughes-Halbert, Ph.D.
Dr. Halbert received her doctorate in personality psychology from Howard University in 1997. In addition to her doctoral training, Dr. Halbert completed pre- and postdoctoral training at the Lombardi Cancer Center. In 1995, she received a predoctoral supplemental award from the National Institutes of Mental Health to evaluate psychosocial and sociocultural influences on family communication about genetic testing and in 1997 she received a postdoctoral supplemental award from the National Cancer Institute to evaluate the process and content of family communication about genetic testing following disclosure of BRCA1 and BRCA2 test results.
Dr. Halbert’s research focuses on understanding the sociocultural underpinnings of cancer prevention and control behaviors among ethnically diverse populations and translating this knowledge into interventions designed to reduce ethnic and racial differences in cancer morbidity and mortality. She is Director of the Community Cancer Prevention and Control Initiative at the Abramson Cancer Center and is Principal Investigator of a randomized trial funded by the Department of Defense to develop and evaluate a culturally tailored genetic counseling protocol for African American women. A secondary aim of this study is to identify African American women who are most and least likely to benefit from CTGC vs. SGC.
Dr. Halbert is also co-principal investigator for the Penn Center for Population Health and Health Disparities that is funded by the National Cancer Institute. The objectives of this center are to (1) study the interaction between biological, clinical, behavioral and environmental factors predictive of outcomes following a prostate cancer diagnosis; (2) evaluate the contribution of these factors to ethnic disparities in prostate cancer outcomes; and (3) disseminate this information to at-risk populations and the public health community. Dr. Halbert is also director of the Community Outreach and Dissemination Core and is principal investigator for Project #4, Determinants of Ethnic Differences in Quality of Life, within the Penn Center for Population Health.

Rick A. Kittles, Ph.D.
Rick Kittles received a B.S. in Biology from the Rochester Institute of Technology in 1989 and a Ph.D. in Biological Sciences from George Washington University in 1998. He then went to Howard University where he helped establish the National Human Genome Center at Howard University. As co-director of Molecular Genetics he directed large-scale, high throughput genotyping and DNA sequencing projects. From 1997 to 2004, Kittles helped establish and coordinate a national cooperative network to study the genetics of hereditary prostate cancer in the African American community. This project, called the AAHPC study network, successfully recruited over 100 multiplex African American hereditary prostate cancer families and serves as a model for recruitment of African Americans in genetic studies of complex diseases.
Genes may play a strong role but epidemiological studies suggest that prostate cancer risk is largely determined by gene and environmental interactions. Increased attention has focused on Vitamin D3 and prostate cancer risk, because of its influence on prostate cell division and inhibition of proliferation. However, the metabolism and physiological actions of the vitamin vary and are modified by genetic and environmental factors such as ultraviolet radiation (UVR) exposure, skin color, diet and genes involved in Vitamin D synthesis, metabolism and action. We are currently studying modifiers of serum 25-hydroxyvitamin D [25(OH)D] levels in order to improve our understanding of the role Vitamin D plays on prostate cancer susceptibility in African Americans. It is likely that this work will contribute to better treatment options and more focused prevention strategies.
Kittles is well known for his research of prostate cancer and health disparities among African Americans. He has also been at the forefront of the development of ancestry-informative genetic markers, and how genetic ancestry can be used to map genes for common traits and disease. Kittles work in 2002 on CYP3A4 genetic variants and prostate cancer risk was the first to show that population stratification due to admixture could be a major problem in genetic association studies of AAs. Kittles’ lab has worked extensively on the use of genetic markers to estimate ancestry among African Americans. They have identified and developed several panels of autosomal SNP markers which can be used to extract continental ancestry information in African Americans. The ancestry estimates using these AIMs allow for the detection of population structure, identification of outlier individuals with extremely high European ancestries in our AA cohorts, and/or to utilize the individual ancestry estimates as additional covariates in the association analyses.
