Biography

Dr. Ajay Singh is a tenured Professor of Cell and Molecular Biology in the School of Medicine at the University of Mississippi Medical Center. He is also the Associate Director of Basic and Translational Research at the Cancer Center and Research Institute. His laboratory focuses on the identification of novel tumor-associated genes and how they impact the behavior of the tumor cells. His lab is also interested in understanding how the tumor cells communicate with its surroundings to become more aggressive and therapy resistant and if targeting of these tumor-stromal interactions could be exploited for cancer prevention and therapy. Another focus is to understand the molecular dissimilarities in tumors from patients of different racial and ethnic backgrounds and investigate their roles in disparate clinical outcomes. He has published extensively, holds multiple US patents, and is a co-founder of a small Biotech company, Tatva Biosciences. He has received numerous honors and awards for his scientific and scholarly accomplishments and has received funding from major federal agencies including NIH, DOD, and NSF, as well as from the state health departments and private foundations. He also actively serves on national and international grant study sections and is a member of the editorial boards of several scientific journals.
