Dr. Yuanyuan Li received her Ph.D. in Oncology from the Chinese Academy of Medical Sciences and Peking Union Medical College, China, in 2006. She then began her postdoctoral training in Dr. Tollefsbol’s lab at University of Alabama at Birmingham (UAB). Dr. Li was appointed as Assistant Research Professor in the Department of Biology at UAB during 2011 to 2013. She was recruited as an Instructor in Division of Hematology and Oncology of Department of Medicine at UAB since 2013.
Her research interests primarily focus on epigenetic regulation of nutritional components in cancer prevention and therapy. She also shows interests in nutrition regulated-aging control and longevity. She authored over 20 scientific peer-reviewed papers in different prestigious journals and also served as an invited scientific reviewer for many highly respected journals. Her research contributions have received international recognition. Especially, one of her papers was selected for press release by the Editors of the FASEB Journal and has been extensively reported by various media presses. This paper was also been awarded best paper by UAB-based investigator(s) in the area of obesity or nutrition. Dr. Li was frequently 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 Susan G. Komen for the Cure Foundation. During her postdoctoral training, Dr. Li received a Postdoctoral Award (PDA) by the 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.
