- I am a quantitative biologist working at the intersection of cancer research, immunology and virology. Our lab uses tools from theoretical physics, mathematics and computer science to better understand host-virus interactions and the role they play in cancers. Previously, we studied how patterns in the evolution of RNA viruses can be used to infer the nature of host innate immune forces on viruses – with an emphasize on distinguishing highly pathogenic viruses, such as avian influenza, from other circulating strains. Using tools from statistical physics and information theory, we modeled how influenza evolves to avoid using certain RNA motifs independently of protein evolution, patterns in viral reassortment in segmented viruses, and genome organization in HIV and HSV. Our goal is to translate these results into experimentally testable hypotheses and clinically meaningful outcomes.
The significance of the mechanisms driving viral evolution and host-virus interactions in cancer has recently become fully appreciated. As a result we have begun to apply our approaches to problems in cancer immunology. We are working to quantify the role of the immune system in several cancers, the interaction of host genomic material with immune receptors, and the role of viruses in cancers. At the same time we continue to develop novel quantitative approaches to a variety of problems in genome evolution.

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. Greenbaum did not report having any of the following types of financial relationships with industry during 2014 and/or 2015: 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.
Mount Sinai Health System (MSHS) physicians - including those employed by MSHS - do not always participate in the same health plans in which MSHS hospitals or facilities participate.
