Ramon Durazo-Arvizu, Ph.D.‌ is a Professor of Public Health Sciences and has a strong background in mathematics and computer intensive statistical methods. He received his Ph.D. from the University of Arizona in Applied Mathematics, where he spent three years teaching mathematics and statistics courses. Additional teaching and research experience was gained through work at:

-The Arizona Cancer Center in Tucson, Arizona
-The University of Sonora, Hermosillo, Master’s program in Psychology and Business Administration
-The Mayo Clinic Cancer Center in Rochester, Minnesota
-The Medical University of South Carolina
-Northwestern University Medical School
-The Department of Public Health Sciences at Loyola University Medical Center where he serves as the head of the Biostatistics Division and co-director of the Master's Program in Clinical Research Methods

Dr. Durazo-Arvizu’s experience in applied statistics includes the analysis of time to an event data (Survival Analysis), multivariate linear and logistic regression, the genetics of hypertension, and the analysis of longitudinal data. In addition, he has gained extensive experience analyzing national data bases, including NHIS, NHANES, and has developed better models to explain the relationship between body mass index and mortality in blacks and whites after adjusting for relevant risk factors. In particular, he has combined existing statistical methods with newer computing techniques, such as bootstrapping and approximate randomization tests, to arrive at models that provide a better fit of the association between body mass index and all-cause mortality. Dr. Durazo-Arvizu has ample experience in statistical consulting with the different health sciences departments including Anesthesiology, Emergency Medicine, Pediatrics, Oncology, Endocrinology, Psychiatry (Alcohol and Drug Abuse Treatment), Rheumatology, Cardiology, Preventive Medicine, and others.

Dr. Durazo-Arvizu is an active member of the American Statistical Association. In 2000, he served as the program chair for the section in Epidemiology. He has organized sessions on Minority and Health and Diversity and the Risk of Cardiovascular Disease for the Association annual meetings and been appointed to the Committee of Minorities in Statistics (2003-2005, 2005-2008). He is also a member of the Eastern North American Region (ENAR) of the International Biometry Society for whom he moderated a workshop to discuss issues related to minority graduate students in Biostatistics. He is a member of the Society for the Advancement of Chicanos and Native Americans in Science (SACNAS).
