Dr. Mark A. Feitelson attended Cypress College (Cypress, CA) from 1970-72, and then received a B.S. degree in biology from the University of California, Irvine in 1974. Advanced studies resulted in a Ph.D. in Microbiology and Immunology from the UCLA School of Medicine in 1979. He was then an American Cancer Society postdoctoral fellow in the Department of Medicine at Stanford University from 1980-1982, where he started his work with hepatitis B virus (HBV). Dr. Feitelson was then recruited to the Fox Chase Cancer Center by Dr. Baruch Blumberg (who won the Nobel Prize for his discovery of HBV) where he continued his work in HBV. In 1988, Dr. Feitelson became an independent faculty member at the Fox Chase Cancer Center at the rank of Associate Member. In 1991, Dr. Feitelson was recruited as an Associate Professor in the Department of Pathology, Anatomy and Cell Biology at Thomas Jefferson University, and from 1997-2007 has been a full-professor in the same department. He also held a secondary appointment in the Department of Microbiology and Immunology within the Kimmel Cancer Center at Jefferson. During this time, Dr. Feitelson ran a CAP certified clinical molecular diagnostic lab in microbiology for Thomas Jefferson University Hospital. Dr. Feitelson is presently Professor of Biology at Temple University and Associate Director of the Temple Biotechnology Center. Dr. Feitelson has over 100 publications in highly ranked international scientific journals, has written two books; delivered more than 160 oral presentations and/or posters at national and international scientific meetings, and has delivered more than 100 invited lectureships all over the world. Dr. Feitelson has recently been named outstanding alumnus of Cypress College.

Professor Sen-Yung Hsieh earned his MD degree from the National Yang Ming University in 1983, and obtained his PhD in Molecular Virology and Pathology from University of Pennsylvania in 1991. He received his clinical training in internal medicine, and subsequent a specialty in hepatogastroenterology in Chang Gung Memorial Hospital, Linko, Taiwan. He initially focused on the molecular virology and epidemiology of human hepatitis viruses. His team for the first time identified the zoonotic transmission of hepatitis E virus from swine to humans in 1998, which was later found in other wild and domestic animals as natural reservoirs for sporadic hepatitis E in Japan, western countries, and other parts of the world. Currently, Dr. Hsieh is interested in elucidation the molecular mechanisms involving in carcinogenesis of human hepatoma. By integration of both functional genomics and molecular and cellular biology, he has identified novel oncogenes, tumor suppressor genes, and pathways that play significant roles in oncogenesis of human hepatoma. His works have been published in J Virology, Nucleic Acid Res, PNAS, Cancer Research, Oncogene, Proteomics, J Proteome Res, Mol Cell Proteomics, J Hepatology, and Hepatology
