Associate Professor in the Department of Biostatistics

Department of Biostatistics

Dr. Ngo is Co-Director of Biostatistics in the Division of General Medicine at Beth Israel Deaconess Medical Center, and Associate Professor of Medicine at Harvard Medical School, and Associate Professor of Biostatistics in the Department of Biostatistics at Harvard T.H. Chan School of Public Health. He is principal investigator (MPI with Dr. Ellen McCarthy) of a NIH-supported project on competing risks which aims to implement the Fine-Gray competing risks method for the Cancer Intervention and Surveillance Modeling Network (CISNET) models. Dr. Ngo is also site PI of a PCORI studyn (PI: Dr. Murray Mittleman) of case-only methodology, and a training grant to teach biostatistics to faculty members in Vietnam. Dr. Ngo is co-investigator on several ongoing NIH-supported studies which include the assessment of potential proteomic, metabolomic, and lipidomic biomarkers in relation to delirium, long-term cognitive declines and Alzheimer’s disease in elderly patients who undergo elective surgery (PI: Dr. Sharon Inouye,  Dr. Edward Marcantonio, Dr. Towia Libermann), the modeling of cardiac long term outcomes including mortality using structural and functional imaging parameters from cardiac magnetic resonance technology (PI: Dr. Reza Nezafat), and the estimation of the effect of intranasal insulin treatment on cognitive decline functions in diabetic patients (PI: Dr. Vera Novak). Dr. Ngo also participates in the research training program of fellows, residents, students at the medical school, and the school of public health. Dr. Ngo is the past chairperson of the 9-member Committee on Statistics and Disability for the American Statistical Association, past member of the Editorial Review Board of the Journal of Clinical Endocrinology and Metabolism, is currently an editorial board member and associate editor for the International Journal of Statistics and Management System, and the Journal of Cardiovascular Magnetic Resonance. Dr. Ngo received his Ph.D. in Biostatistics at the University of California at Berkeley.
