The research interests of the program faculty are described below:

Dr. David Bishai  is a pediatrician and health economist who has expertise in cost-effectiveness analysis and impacts of guidelines development. Dr. Bishai has conducted extensive research on applying economic methods to models of intra-household decisions affecting health status. Past investigations include an econometric analysis of condom use in teenagers, cost-benefit analyses of gonorrhea and Chlamydia control, and the acceptability of self-collected samples for HPV testing.
Recent Publications  Selected current research

Dr. Robert Bollinger is the director of the Johns Hopkins Center for Clinical Global Health Education.  In collaboration with the National AIDS Research Institute (NARI) in Pune, India, Dr. Bollinger has established a research STD and HIV clinic which has taken a lead role in determining STD and HIV incidence and prevalence, and the interaction between STDs and HIV.  Dr. Bollinger also participates in the HIVNET evaluation studies of vaginal microbicides to prevent STD/HIV infection.
Recent Publications  Selected current research

Dr. David Celentano has been Principal Investigator on a number of HIV/AIDS behavioral intervention field trials, including the NIMH Multisite HIV Prevention Trial, the CDC-supported Women in Group Support (WINGS), the Young Men’s Survey (HIV risk in young men who have sex with men), and peer network intervention projects among young methamphetamine users in Thailand.
Recent Publications  Selected current research

Dr. Richard Cone’s  primary research interest is to develop improved barrier methods for protecting against STDs and unwanted pregnancy. Key projects include the pathogenesis of bacterial vaginosis, development of detergent-free microbicides, an investigation of the relationship between microbicides and bacterial vaginosis (from a product development perspective), and the use of barrier methods and lubricants to prevent upper-tract exposure to STD pathogens. 
Recent Publications  Selected current research

Dr. Jonathan Ellen is an adolescent medicine specialist whose research focuses on understanding  the key behavioral determinants associated with an adolescent’s acquisition of an STD. His funded research includes collaborative studies of community-basis for STD risk, STDs in juvenile detention facilities, and the relationship between social networks and geographic location in determining STD risk. 
Recent Publications  Selected current research

Dr. Emily Erbelding  is director of clinical services for the Baltimore City Health Department STD Program, and is an expert on the operational/public health aspects of STD care delivery and STD epidemiology. Her research has focused on STD incidence in HIV-infected persons and in elucidating medical-based key determinants of high risk behaviors, including the role of mental illness as a mediating variable in behavioral interventions. 
Recent Publications  Selected current research

Dr. Charlotte Gaydos is a microbiologist whose major interest has been in developing and conducting field trials for STD diagnostic tests, including the now widely-used urine-based nucleic acid amplification tests for gonorrhea and chlamydia. Her work has encompassed defining the technical aspects of testing (e.g. instrumentation, specimen adequacy), and the application of testing to a wide variety of settings. Her lab is a Core Diagnostic Laboratory for many national and international grants.
Recent Publications  Selected current research

Dr. Khalil Ghanem’s interests include the mucosal immune responses to STIs and the effects of hormonal contraception on mucosal systemic immune responses. He has also published recently on syphilis treatments among HIV-positive and HIV-negative patients, and on infections in pregnant STD clinic patients. Dr. Ghanem established the Baltimore City Health Department STD Clinic database, a resource that is made available to students working with the Center.
Recent Publications  Selected current research

Dr Vivian Go is an epidemiologist and qualitative researcher who has developed and published ethnographic and epidemiological assessments of STDs in Northern Vietnam. She is conducting an HIV/STD prevention trial among injection drug users and their peer networks in North Vietnamese communities.
Recent Publications  Selected current research

Dr. Patti Gravitt’s research interests are primarily focused on the molecular epidemiology and detection/screening for human papillomaviruses and cervical cancer. She has developed and validated gold standard PCR-based methods for the detection and quantitation of human papillomaviruses. Recent work has been dedicated to understanding the role of HPV viral load in the progression of cervical neoplasia and understanding other biologic and environmental factors that influence detectable viral load in women without evidence of cervical disease.
Recent Publications  Selected current research

Dr. Ronald Gray  is an internationally recognized  reproductive health physician and epidemiologist whose current research interests focus on the relationship between STD and HIV transmission. He is co-principal investigator of the Rakai Health Sciences Program in Uganda, which has evaluated  a series of HIV/STD control interventions. Dr. Gray works closely with the Bill and Melinda Gates Institute for Population and Reproductive Health and has recently been working on the evaluation of male circumcision as an intervention for STD/HIV transmission prevention.
Recent Publications  Selected current research

Dr Carl Latkin is the principal investigator at the Lighthouse, a community-based research center that focuses on health promotion and disease prevention. Dr. Latkin’s research focuses on the social context of risk behaviors, particularly STD/HIV risk among such disadvantaged populations as drug users and sex workers. His intervention and observational studies include analysis of social and personal networks and identifying neighborhood factors important in the development of health behaviors.
Recent Publications  Selected current research

Dr. Lori Leonard is an ethnographer and qualitative researcher with extensive experience in HIV/STD prevention interventions in sub-Saharan Africa, including a World Bank-funded project in Chad examining the impact of oil pipeline construction on HIV/STDs. Her interests have included syphilis prevention in the U.S., STI protection in travelers, and qualitative work in the Baltimore City STD clinics.  She has worked with students in adapting qualitative techniques to clinical and field settings in Baltimore, including exploring ethnographic characterization of patients with gonorrhea, and interviews with commercial sex workers who use intravenous drugs.
Recent Publications  Selected current research

Dr. Kenrad E. Nelson is an infectious diseases physician and epidemiologist whose research interests include STD/HIV incidence in drug users, hepatitis B and C, and structural interventions. Drs. Nelson and Celentano were the principals in developing and implementing (with the Thai Ministry of Health) the 100% Condom Campaign in Thai brothels, which was associated with a substantial decrease in STD and HIV incidence in this population. He is currently developing similar projects and programs in Eastern Europe. 
Recent Publications  Selected current research

Dr. Thomas Quinn is an infectious diseases specialist and the head of the section on international HIV/STD research in the Laboratory of Immunoregulation at the National Institute of Allergy and Infectious Diseases. Dr. Quinn provides CLIA-approved laboratory support for a wide variety of STD/HIV research studies within the Johns Hopkins Medical Institutions. He has worked extensively in developing countries, setting up field HIV/STD labs and developing rapid and cost-effective assays for use in resource-poor settings. His lab was one of the first to develop and evaluate rapid diagnostic and molecular diagnostic assays for HIV, C. trachomatis, N. gonorrhoeae, and T. vaginalis, as well as a multiplex PCR assay for syphilis, herpes and chancroid.
Recent Publications  Selected current research

Dr. Anne Rompalo is an infectious diseases physician whose current research includes evaluation of social networks of persons with syphilis and other STDs, and development of an intervention to prevent douching and bacterial vaginosis. Dr. Rompalo serves as the medical director of the Region III STD/HIV Prevention Training Center which provides clinical training to clinicians.
