Dr. Berhane is a Professor in the Division of Biostatistics, and Director of Graduate Programs in Biostatistics and Epidemiology. He obtained his B.Sc. from Addis Ababa University (Ethiopia), majoring in statistics, M.Sc. degree in statistics at University of Guelph (Canada), Ph.D. degree in biostatistics at University of Toronto (Canada), and a postdoctoral fellowship at Johns Hopkins University (Baltimore, MD). His main research interests are in the development of statistical methods for environmental research, and their application to examination of health effects of air pollution, occupational exposures and climate change. His research is funded via grants from the NIH, US-EPA, HEI and the Canadian IDRC. He is an elected fellow of the American Statistical Association. He is a member of the US-EPA Science Advisory Board, Health Effects Institute Review Committee, and the Biostatistical Methods and Research Design [BMRD] Study Section of the NIH.
