Scientific Integrity Institute


About the Scientific Integrity Institute

Dr. James E. Enstrom is a retired Research Professor (Epidemiology) who held faculty positions at the UCLA School of Public Health and Jonsson Comprehensive Cancer Center. Also, he is President of the Scientific Integrity Institute in Los Angeles. He has a BS in physics from Harvey Mudd College, an MS and PhD in physics from Stanford University, and an MPH and postdoctoral certificate in epidemiology from UCLA. He is a Life Member of the American Physical Society, a Founding Fellow of the American College of Epidemiology, a current member of the ACE Ethics Committee, a biographee in Who’s Who in America, and a recipient of the American Freedom Alliance Hero of Conscience Award.


Dr. Enstrom has authored, primarily as first or sole author, about 50 peer-reviewed articles and book chapters on physics, epidemiology, and scientific integrity.  He has applied his knowledge of the scientific integrity in the experimental science of physics to increasing the scientific integrity in the observational science of epidemiology.  He has published important findings relating healthy lifestyles and good health practices to reduced mortality from cancer, heart disease, and all causes.  Also, he has published detailed criticism of weak epidemiologic relationships that should not be used as the basis for public health policy.  His Scientific Integrity Institute website contains hundreds of documents on air pollution epidemiology, lifestyle epidemiology, and scientific integrity relevant to his research.


During the past twenty years Dr. Enstrom has focused on environmental epidemiology and has published strong evidence that air pollution, particularly fine particulate matter (PM2.5), is not related to total mortality.  This evidence includes the null findings from his independent analyses of the American Cancer Society Cancer Prevention Study cohorts (CPS I and CPS II).  These null findings demonstrate the importance of transparency and reproducibility of research findings and the need for access to underlying data.  In addition, these findings challenge the integrity of air pollution epidemiology and the validity of the EPA PM2.5 National Ambient Air Quality Standard (NAAQS).  Finally, these findings are relevant to the scientific efforts of the CO2 Coalition.
