Stella Tommasi, PhD, MPH
Clinical Assistant Professor
Dr. Stella Tommasi is a research assistant professor in the Department of Preventive Medicine at the Keck Medical School of USC. She is a skilled molecular biologist and an expert in cancer genetics and epigenetics. Her research focuses on elucidating the underlying mechanisms of human cancer. Of special interest is understanding the role played by tobacco toxicants/carcinogens in the development of smoking-associated cancer. These studies can help determine the health risks associated with the use of conventional and new-generation tobacco products (electronic cigarettes), and assist regulatory agencies in the development and evaluation of regulations on tobacco products to protect public health and to reduce tobacco use by minors and other vulnerable populations.
Other areas of research include UV mutagenesis and melanoma, aging and animal models of human cancer. Throughout her career, Dr. Tommasi has taught several undergraduate and graduate courses in health promotion and disease prevention, as well as courses in chemistry and molecular and cell biology.
