Dr. Rohan is a Professor in the Department of Pharmaceutical Sciences in the School of Pharmacy. She also holds appointments in the Department of Obstetrics, Gynecology, and Reproductive Sciences in the School of Medicine and the Clinical Translational Science Institute at the Univerisity of Pittsburgh. Additionally, she is an Associate Investigator at the Magee Womens Research Institute. She obtained a Bachelor of Science in Chemical Engineering from West Virginia University and a Ph.D. in Pharmaceutics from the University of Pittsburgh School of Pharmacy. After completion of her Ph.D. work Dr. Rohan completed a Postdoctoral Fellowship in the Department of Obstetrics, Gynecology, and Reproductive Sciences in the area of Mucosal Immunology at the University of Pittsburgh.

The basis of Dr. Rohan’s research lies in vaginal and cervical delivery as applied in the areas of infectious disease and gynecologic oncology. Particular interests are in studying the role of chemical, physical, and biological properties of vaginal and cervical tissues and fluids in the development of vaginal and cervical products. Specifically, this knowledge is being utilized to develop a product for prophylactic use against Sexually Transmitted Diseases and HIV. Her research also involves the development and optimization of imaging techniques for sentinel node identification in cervical cancer as well as novel delivery systems for chemotherapeutic agents.

Design and development of drug delivery systems for STI/HIV prevention and gynecologic oncology applications.
