    My clinical training is in Infectious Diseases with a specific interest in HIV and my basic science interest is in the biology that underlies chronic HIV infection. HIV is an incurable disease and while antiretroviral therapy is effective at suppressive viremia, long term sequelae of inflammation account for premature aging, higher rates of cardiovascular disease, and neoplasms. My research seeks to identify novel mechanisms of HIV-associated inflammation through membrane signaling.

HIV infection and purinergic signaling

I am interested in understanding the mechanisms that underlie chronic inflammation that causes morbidity and mortality in well-controlled HIV-infected patients. Our laboratory research focuses on the role of purinergic signaling that is required for HIV infection and may activate pro-inflammatory cytokine production.

Industry Relationships

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.

Dr. Swartz did not report having any of the following types of financial relationships with industry during 2015 and/or 2016: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.

Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.

Insurance Information

Physicians who provide services at hospitals and facilities in the Mount Sinai Health System might not participate in the same health plans as those Mount Sinai hospitals and facilities (even if the physicians are employed or contracted by those hospitals or facilities).

Information regarding insurance participation and billing by this physician may be found on this page, and can also be obtained by contacting this provider directly. Because physicians insurance participation can change, the insurance information on this page may not always be up-to-date. Please contact this physician directly to obtain the most up-to-date insurance information.

Insurance and health plan networks that the various Mount Sinai Health System hospitals and facilities participate in can be found on the Mount Sinai Health System website.
