Dr. Chih-Wen Peng, PhD, is a professor in the Institute of Medical Sciences, Tzu Chi University. He received his B.S. degree from National Chung-Hsing University and his PhD from Oregon State University. After his PhD, he was a post-doctoral fellow in Dr. Eliott Kieff’s lab in Harvard Medical School focusing on the interactions of EBV latency products to elucidate how EBV nuclear antigens involve in the latency dependent transcription program. He joined the faculty at department of Life Sciences in 2004 and at the IMS in 2015.
Originally from Taiwan, Dr. Peng originally received his B.S. degree from National Chung-Hsing University. Shortly afterwards, he received his PhD at Oregon State University and completed postdoctoral training with Dr. Elliott Kieff at Harvard Medical School. He joined the faculty at Tzu Chi University as an assistant professor in the Department of Life Sciences working closely within the Institute of Medical Sciences. Dr. Peng has conducted proteomic and epigenetic research to dissect how Epstein-Barr Virus (EBV) exploits or subverts the cellular factors to establish and to maintain the persistency in host cells.
Dr. Peng’s research interest focus on exploring the mechanistic insight of EBV-mediated transformation of human B lymphocytes through targeting to the key viral latent proteins. His group have identified some cellular factors are involved in the establishment and maintence of EBV latency program. In addition, we also advance to anti-EBV compounds discovery. Epstein-Barr Virus (EBV) was the first human tumor virus shown to associate with a broad spectrum of cancers originating from lymphocytes and epithelial cells. EBV related studies have been of huge importance to our understanding of how viruses can cause cancer. The establishment of lifelong latent infection in host cells is a prerequisite process of EBV-induced tumoriegenesis.
Dr. Peng’s research focuses on: (1) Understanding of how EBV latent genes interact and modulate cellular factors to build up the permanent infection in host cells. (2) Identification of new biomarkers and therapeutic targets for EBV associated cancers. (3) Development of new anti-virus protocol for being applied to translation medicine research of EBV-associated malignancies.
