Steven Josefowicz, PhD
Steven Josefowicz is an Assistant Professor in the Department of Pathology and Laboratory Medicine, Division of Experimental Pathology. Steven has appointments in the Immunology and Microbial Pathogenesis (IMP) Program and the Physiology, Biophysics, and Systems Biology (PBSB) Program. After a BA from UC Berkeley and three years as a research tech working in the area of human immunology and HIV at UCSF, Steve conducted his graduate work with Alexander (Sasha) Rudensky at the University of Washington in Seattle, WA and then at Memorial Sloan Kettering Cancer Center in New York, NY. His PhD work focused on mechanisms of immune tolerance and the differentiation and function of regulatory T cells-- how our powerful immune systems can so effectively combat pathogens while tolerating our own tissues, food, and commensal microbiota. He then joined the laboratory of C. David Allis at The Rockefeller University to study epigenetic mechanisms underlying cellular differentiation and stimulation events in the immune system. Joining Weill Cornell Medicine in May 2017, his ongoing work focuses on fundamental questions of genome organization and regulation, especially as it pertains to rapid cellular responses, including innate immune cell responses to pathogen sensing. This research is also revealing links between aberrant activation of “signaling to chromatin” pathways, epigenetic alterations, and disease states, including cancer, chronic inflammatory conditions, and accelerated aging.
