Welcome to the Weill Cornell Medicine Division of Infectious Diseases (ID). Our mission is to design and conduct cutting edge research, to deliver outstanding clinical care, and to provide the highest quality education and training in infectious diseases. We have 60 full-time faculty members, and our division includes basic, translational, clinical and epidemiological research programs, inpatient and ambulatory clinical services at NewYork Presbyterian Hospital/Weill Cornell Medical Center, and the ID Fellowship Training Program.


The main laboratory research projects in our division focus on antibiotic and antifungal drug development, bacterial pathogenesis, HIV and other retroviruses, influenza, malaria/babesia, and tuberculosis. Major clinical research projects investigate antimicrobial drug resistance, hepatitis, HIV/AIDS, hospital epidemiology/infection control, human papillomavirus, respiratory viruses, and transplantation/oncology ID. Furthermore, in collaboration with The Center for Global Health, we have clinical, research and training programs in Brazil, Haiti, and Tanzania, with full-time faculty and/or fellows at each site. Overseas research interests at these locations include diarrheal illnesses, HIV/AIDS, HTLV-1, leprosy, malaria, leishmaniasis, schistosomiasis, and tuberculosis.

Since the beginning of the COVID-19 pandemic, our division has been engaged in research on SARS-CoV-2/COVID-19 pathogenesis, therapeutics, epidemiology/outcomes, and vaccine development. Additionally, ID division members are leading national research to understand the effectiveness of antiviral therapy for Mpox.

Current annual funding for all of the sponsored research and training in the Division of Infectious Diseases in 2022-2023 exceeds $37 million.

Clinical Care

Our clinical programs provide primary and consultative care in both outpatient and inpatient settings for patients in the greater New York City area. Weill Cornell ID Associates houses several outpatient programs including general ID consultations, travel medicine, transplant/oncology ID, general ID fellows clinic, and OPAT. Patients are seen at the uptown Cornell and the Lower Manhattan campuses.

The HIV/AIDS Program provides care to over 3,000 persons living with HIV at our Center for Special Studies in two locations: on the Upper East Side and in Chelsea. In both locations, providers conduct clinical and translational research in our HIV Clinical Trials Unit.

More than 1,000 inpatient consultations per year are seen at NYP/Weill Cornell, a large 867-bed tertiary care hospital, at NYPH/Lower Manhattan Hospital, and at our affiliated institution, the Hospital for Special Surgery.

Other major clinical programs in the ID Division are the Transplant Oncology ID Program and the Hospital Epidemiology/Infection Control Program.
