Prior to joining NYMC, Chioma M. Okeoma, Ph.D., was an associate professor in the Department of Pharmacology, Stony Brook University Renaissance School of Medicine, Stony Brook, New York. Dr. Okeoma completed her postdoctoral training at the University of Pennsylvania from where she moved to the University Iowa as an assistant professor. She has been in the forefront of cutting-edge research for which she has received many awards and recognitions, including a medallion from the Australian College of Veterinary Scientists, as well as a recipient of the Andy Kaplan Prize from Cold Spring Harbor Retrovirus Meeting. Dr. Okeoma is a fellow of the Lovelace Biomedical in Albuquerque, New Mexico, as well as a recipient of the Iowa Women of Innovation Awards by the Technology Association of Iowa.

Research

Dr. Okeoma’s laboratory focuses on understanding how host factors expressed in host cells or present in extracellular structures, such as extracellular vesicles and extracellular condensates, protect the host against infective agents or facilitate disease manifestation. Her laboratory has led in defining the role of BST-2 in breast cancer as reported in multiple publications. Additionally, her laboratory studies the interaction of cellular components and extracellular structures and how they interplay to produce spatiotemporal phenotypes observed in physiological and pathophysiological states.
