Dr. Sugár has made important contributions to theoretical biophysics by 1) deriving exact solutions of the fundamental equations of fluorescence and NMR spectroscopy, 2) constructing stochastic models of cell electroporation and electrofusion, 3) simulating two-component phospholipid membranes by Monte Carlo techniques, 4) developing a statistical mechanical model of sterol/phospholipid mixtures, 5) modeling peripheral protein adsorption on the water/lipid interface, and 6) studying the effect of  epithelial membrane geometry on autocrine/paracrine signaling. Recently he also contributed to the reliable analysis of high dimensional flow cytometry data by developing a fast clustering method and an improved method for compensation.

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. Sugar 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.
