Coming from Health Canada in 2001, Dr. Wen has worked with Dr. Mark Walker, to create an internationally recognized program of research in perinatal epidemiology. The focus of this program is fetal origins of adult disease, perinatal environmental epidemiology, and global perinatal health. In 2009 they were awarded a $6.5 million grant to study the effects of folic acid supplementation in decreasing the risk of pre-eclampsia. In 2016 they were awarded a $ 9.5 million CIHR foundation program grant to conduct epidemiologic studies to improve maternal and child health. In the past two decades, Dr. Wen has served for the Ottawa Hospital Research Ethics Board and various committee meetings at the Department of Obstetrics and Gynecology and School of Epidemiology and Public Health, University of Ottawa.

Dr. Wen has been teaching research methodology and epidemiologic principles at the undergraduate, post-graduate and fellowship levels. He has been invited to give lectures in the National Institute of Child Health and Human Development, Thomas Jefferson University, National University of Taiwan, McGill University, and several key medical schools in China.

Dr. Wen has published over 410 peer-reviewed articles in numerous top tier journals.
