The SUDDEN team consists of researchers from medicine, epidemiology, statistics, demography with experience setting up protocols based on death certificate date and expertise in analyzing medical and death certificate coding data. Alongside various researchers, SUDDEN consists of medical students, international visiting medical students, post-graduate interns, and undergraduate interns.

Ross J Simpson, Jr. MD, PhD
Principal Investigator
“We need to increase understanding of the epidemiology and potential causes
of out-of-hospital sudden unexpected death (OHSUD) in order to develop individual,
community-based, and regional interventions to reduce the incidence of OHSUD.”

Irion “Chip” Pursell, RN, BSN
Co-Principal Investigator
“The SUDDEN project is a research platform that will define public policy,
surveillance methodology and prevention strategies related to sudden unexpected death. Our goal is to reduce the incidence of OHSUD in the populations we serve.”

J. Paul Mounsey, MD
Co-Principal Investigator
“It is only by identifying people who suffer sudden unexpected death that
we will be able to monitor the changing patterns of OHSUD in our society.
This is the number one killer in the United States today, and it deserves our attention.” |

The SUDDEN Project aims to create new knowledge around the demographic and biomedical factors that influence Out of Hospital Sudden Unexpected Death (OHSUD) throughout the United States, improve targeted prevention strategies, and reduce the burden of OHSUD through meaningful community and academic partnerships.
