Areas of Interest: 

Dr. Zuo-Feng Zhang's research focuses on the molecular epidemiology of cancers of the bladder, prostate, esophagus, stomach, head and neck and cervix. Other research interests include nutrition and cancer, epidemiology of second primary cancer; methodological issues in the use of tumor markers in cancer epidemiology; and progression and survival of cancer.

Zhang's research group in the molecular epidemiology laboratories is currently working on mutations, methylations, polymorphisms or SNPs of tumor suppresser genes such as TP53 and p16, of Phases I and II genes such as GSTs, NATs, and CYP450s, and of DNA repair genes such as XRCC1. The major focus is to evaluate the main effects of these genes on the risk of cancers and to assess potential gene-environment interactions.


ZUO-FENG ZHANG, M.D., Ph.D. is a Professor of Epidemiology, Co-Director of the UCLA Center for Environment Genomics, Director of Molecular Epidemiology Training Program, and Scientific Director of UCLA Central Tumor Registry. Dr. Zhang has been a Fellow of the American College of Epidemiology (ACE) since 1999 and he served as Member of the Board of Directors of the American College of Epidemiology from 2002 to 2005. Dr. Zhang served as a regular member of NIH Epidemiology of Cancer Study Section (EPIC), is currently serving as a regular member of the NCI-J study section, and as an ad hoc member in numerous NIH peer review study sections. Dr. Zhang served as a World Health Organization (WHO) Consultant for National Noncommunicable Disease Prevention and Controls in China. Dr. Zhang was a barefoot doctor in China from 1969 to 1973. He worked as a preventive doctor in a Schistosomiasis Control Program from 1975 to 1978. Following a Medical Degree in Preventive Medicine from Shanghai Medical University in 1983, he studied cancer epidemiology under Professor Shun-Zhang Yu in the graduate program of Shanghai Medical University from 1983-1987. Thereafter, he did post-doctoral training at the International Agency for Research on Cancer (IARC), World Health Organization, Lyon, France from 1987-1988, under supervision of Dr. Max Parkin. Several years later, Dr. Zhang graduated with a Ph.D. degree in cancer epidemiology, from State University of New York at Buffalo in 1991, where he worked with Dr. Saxon Graham, followed by positions as an Assistant and Associate Member (Professor) of Memorial Sloan-Kettering Cancer Center in New York City and as an Assistant Professor at Cornell Medical College from 1991 to 1997. Finally, he accepted a position as a Tenured Associate Professor of Epidemiology at the University of California, Los Angeles in 1997, and advanced to Full Professor of Epidemiology in 1999.
