Charlotte A. Gaydos, DrPH, MPH, MS

Charlotte Gaydos, DrPHPrincipal Investigator

Dr. Gaydos is a Professor in the Division of Infectious Diseases, Department of Medicine of the Johns Hopkins University School of Medicine and has joint appointments in the Emergency Medicine Department and Epidemiology and Population, Family and Reproductive Health at the Bloomberg Johns Hopkins School of Public Health. She is the Director of the International Sexually Transmitted Diseases Research Laboratory.  She received her B.S. in medical technology and her M.S. in medical microbiology from West Virginia University.  Her M.P.H. and Dr.P.H. in Infectious Diseases and Immunology were received from Johns Hopkins University School of Hygiene and Public Health.  Dr. Gaydos has extensive laboratory expertise with over 40 years experience in microbiology.  She has authored 17 book chapters, over 230 research articles, and over 400 research abstracts and oral presentations. 

Dr. Gaydos has conducted many clinical trials for new diagnostics for Chlamydia trachomatis and Neisseria gonorrhea.  She has worked for the last 20 years in the STD research field performing original research developing DNA amplification tests for Chlamydia trachomatis, C. pneumoniae, C. psittaci, Trichomonas vaginalis, N. gonorrhoeae, Mycoplasma genitalium, and the agents of genital ulcer disease.  An Internet project for enhanced community chlamydia screening using self-administered vaginal swabs, currently in progress, demonstrates an effective method for reaching women and men who may not attend clinics.  Her laboratory has served as the Core Diagnostic Laboratory and as the Reference Laboratory for many national and international grants for collaborative studies of sexually transmitted diseases, respiratory diseases, and trachoma. The laboratory is CLIA-licensed and State of Maryland certified for diagnostic assays.  Dr. Gaydos is co-investigator for the Diagnostic Core for the Mid-Atlantic Center of Excellence for Biothreat and Emerging Infectious Diseases.  She is the recent recipient of an NIH funded Center grant to develop point-of-care tests for STDs. 

Dr. Gaydos serves on the National Chlamydia Laboratory Committee, sponsored by the Centers for Disease Control and Prevention (CDC) and has served on CDC expert panels for laboratory diagnosis of STDs.  She is the Director of the North American Branch for the International Union Against Sexually Transmitted Infections (IUSTI), serves on the Executive Boards of the American Sexually Transmitted Diseases Association (ASTDA) and International Society for Sexually Transmitted Diseases Research (ISSTDR), and serves on the Editorial Board for the Sexually Transmitted Diseases Journal.
