Personal Statement

My medical training coincided with a time of intense progress in the treatment of HIV infection following the discovery of protease inhibitors and effective antiretroviral combination therapy.  During my medical school clinical rotations at New York Presbyterian Hospital-Columbia and residency training at New York Presbyterian Hospital-Cornell, I observed the life-saving capacity of these therapies as they became established in clinical practice. I also had the opportunity to care for patients who had exhausted the currently available drug options and were receiving newer agents through studies such as those conducted at the Cornell Clinical Trials Unit. During these years of progress in the management of HIV, I witnessed viral hepatitis, particularly hepatitis C infection, emerge as an increasingly common cause of morbidity and mortality in HIV-infected persons; however, the available therapies for hepatitis C continued to fail most HIV-infected patients. These experiences influenced my decision to further my training in the subspecialty of Infectious Diseases, focusing on care of patients coinfected with HIV and viral hepatitis infections. In addition, I began research with the aim of optimizing treatment of Hepatitis C in HIV-infected patients.   Today, I continue this research at the Cornell Clinical Trials Unit in collaboration with the Center for the Study of Hepatitis C. I also care for patients living with HIV infection (Center for Special Studies) and viral hepatic infections (Hepatitis Clinic). In addition, I am fortunate to participate in the teaching of medical students, residents and fellows.


Dr. Marks received Internal Medicine residency and Infectious Diseases fellowship training at New York-Presbyterian Hospital (Cornell), where she focused her clinical training and research on HIV and hepatitis virus infections, and she completed Weill Cornell's Master's Degree in Clinical Investigation.  Her current research focuses on improving treatment outcomes in patients with HIV and hepatitis virus co-infections and includes studies of acute HCV as well as new treatment strategies for chronic HCV.  She was the vice chair of an AIDS Clinical Trials Group (ACTG) multi-center study, currently serves on 3 other ACTG hepatitis protocol teams, and is a member of the ACTG Hepatitis Transformative Science Group.  She is co-investigator in the Cornell HIV/AIDS Clinical Trials Unit and Center for Study of Hepatitis C, where she conducts treatment studies related to HIV and HCV.  She also sits on IDSA, AASLD, and IAS-USA’s joint guidelines panel for “Recommendations for testing, managing and treating hepatitis C”.
