Dr. Tom Hei's research focuses on environmental carcinogenesis, specifically mechanisms of chemical and radiation carcinogenesis/mutagenesis at the cellular and molecular levels. Dr. Hei is working on ongoing funded research programs focused on the basic cellular and molecular mechanisms of environmental carcinogens such as tobacco smoke, radon, asbestos fibers, and heavy metals. Immortalized human bronchial and breast epithelial cell models are used to examine the molecular mechanisms involved in the multistage nature of human carcinogenesis.

Select Global Activities
Center of Excellence in Radiological Health Sciences Nagasaki University, Japan, Japan: Dr. Hei is participating in and directing this international collaboration in the research and teaching of radiation biology to graduate and medical students and postdoctoral fellows between members of the consortium. The collaboration aims to promote a better understanding of low dose radiation risk to the general public and provide educational forum for the various activities.
Radiation biology of targeted irradiation: This project aims to provide training and research opportunities to graduate students and postdoctoral fellows of the Chinese Academy of Sciences in radiological sciences, specifically the use of the Columbia Microbeam that can selectively target either the cellular nuclear or cytoplasm for various genotoxic endpoints.
Environmental Health and basic mechanisms of carcinogenesis: This project promotes collaboration between the Institute of Radiation Medicine, National Institute of Radiological Protection, both of Beijing, China and the Department of Environmental Health Sciences of Columbia University in research and teaching of environmental cancer, specifically those of lung and breast.
