Dr. Dong Fang received his Ph.D. from Tsinghua University, China in 2012. After that, he worked for four years at the Mayo Clinic, USA, where he focused on understanding the role of epigenetic regulation of gene expression and on how oncohistones reprogram the epigenetic landscape and gene expression to drive tumorigenesis. In 2016, he joined the Institute for Cancer Genetics, Columbia University Medical Center, New York, USA as an Associate Research Scientist, and continued his research on oncohistones. He joined Zhejiang University in 2018, and has since established his own laboratory at its Life Sciences Institute, focusing on histone mutations and epigenetic inheritance. Junhong Han, Ph.D. is a Primary Investigator at the State Key Laboratory of Biotherapy, Sichuan University. He is also a Professor at the West China School of Medicine and a member of the Cancer Center at West China Hospital, Sichuan University. His main research interests are in the areas of DNA replication, epigenetic modifications in genome stability, and cancer epigenetics. Currently, Dr. Han is also working to identify and analyze the genes, pathways, and networks involved in cancer chemoresistance, and to understand the transcriptional heterogeneity for pancreatic ductal adenocarcinoma primary tumor with metastasis. Dr. Han received his Ph.D. in Cell Biology from Tokyo Institute of Technology, Japan and completed his post-doctoral training at the Mayo Clinic in Rochester, Minnesota, USA.
