Henri leads health-economic modeling projects as a principal investigator. He has developed models in the therapeutic areas of breast cancer screening, cardiovascular prevention, diabetes, chronic kidney disease, migraine, cancer pain, HIV, chronic hepatitis B, Alzheimer’s disease, Crohn’s disease, and psoriatic arthritis. Henri specializes in individual-level simulations and is a leader in the application of the discretely integrated condition-event (DICE) simulation methodology, with DICE models in five therapeutic areas. His work has been published in Cancer Prevention Research, Atherosclerosis, Clinical Therapeutics, and Diabetes, Obesity, and Metabolism. Henri joined Archimedes in 2012, which became part of Evidera in January 2014. Previously, he worked as a research assistant at the Harvard Center for Risk Analysis (now the Center for Health Decision Science) developing simulation models of cervical and colorectal cancer screening. He holds a PhD in biology from Stanford University as well as a bachelor of arts in applied math and a master of arts in biology from Harvard University.
