Yuanyan Li. Office Hours: By appointment

Education:
  • PhD, Chinese Academy of Medical Sciences and Peking Union Medical College, China, Oncology

Dr. Yuanyuan Li received her PhD in Oncology from the Chinese Academy of Medical Sciences and Peking Union Medical College, China, in 2006. She began her postdoctoral training in Dr. Tollefsbol’s lab at University of Alabama at Birmingham and was an assistant research professor in the Department of Biology during 2011 to 2013. She was recruited as an instructor in Division of Hematology and Oncology of Department of Medicine at UAB in 2013, then returned to the Department of Biology as Assistant Research Professor in March of 2016.

Dr. Li's research interests primarily focus on epigenetic regulation of nutritional components in cancer prevention and therapy. She is also interested in nutrition regulated-aging control and longevity. She has authored over 20 scientific peer-reviewed papers in prestigious journals and served as an invited scientific reviewer for many highly respected journals. Her research contributions have received international recognition.

She is often invited to give oral presentations at different academic occasions and to present her studies at several national and international conferences. Dr. Li served as PI or co-investigator on several extramural research grants from funding agencies including the American Institute for Cancer Research (AICR), the National Institutes of Health (NIH), and the Susan G. Komen for the Cure Foundation. During her postdoctoral training she received a Postdoctoral Award (PDA) by AICR, the national leading cancer foundation charity. She also received grants as principal investigator (PI) by NIH/NCI R03, the American Cancer Society (ACS), and the UAB Comprehensive Cancer Center for her junior faculty career development.

My research primarily focuses on epigenetic regulation of dietary components in cancer, and epigenetic reprogramming in transgenerational cancer and obesity interfering. Nutrition is a chief contributor to the regulation of gene expression in cancer development by impacting epigenetic pathways. Therefore my primary research strategy is to investigate the molecular epigenetic mechanisms of the bioactive botanical compounds in prevention and therapy of human diseases such as breast cancer and obesity. I have more than 10 years of experience in cancer research and my research area has important translational potential.
