Dr. Davis is an epidemiologist and data scientist with specialized experience in human health risk assessment, food safety, environmental health, and infectious diseases. He applies his rigorous training in epidemiology and biostatistics to a variety of public health topics, including probabilistic exposure assessment and dose-response methodology, respiratory and foodborne infectious diseases, and physiologically-based pharmacokinetic models.

Dr. Davis conducts exposure assessments using large databases including publicly available data sources such as NHANES and the U.S. FDA Total Diet Study and performs dose-response modeling using both the PROAST and BMDS software. His expertise extends to both chemical and biological health hazards, including heavy metals and SARS-CoV-2. Dr. Davis has conducted several large and multifaceted systematic reviews and risk assessments related to the safety and critical control points of regularly-consumed food products. He has extensive experience in complex biostatistical methodology, including mixed-effect modeling and spatial-temporal analysis, which he applies to estimating regular dietary patterns from large survey databases, evaluating microbial and chemical contaminants in food products, and deriving dose-response relationships for a variety of chemicals. Dr. Davis is also well-versed in complex human observational research including but not limited to the field of nutritional epidemiology. He has been involved in comprehensive reviews of infectious disease dynamics, such as the spread of COVID-19.

Dr. Davis has worked with food and ingredient manufacturers, trade associations, and insurance companies. He has also played an active role in several regulatory submissions to the U.S. FDA and U.S. EPA, including novel food products, food and color additive petitions, as well as GRAS notifications. He has provided scientific support to litigation related to COVID-19 business interruption as well as nutritional epidemiology and food safety. Dr. Davis has developed and executed several statistical analyses related to the residual concentrations and health effects of pesticides applied to crops, as well as to the composition of the human microbiome. Dr. Davis is also experienced in intake assessments including those applied to Proposition 65 claims.

Prior to joining Exponent, Dr. Davis was on the faculty at the Johns Hopkins Bloomberg School of Public Health, Department of Epidemiology, managing a large multi-year research project on the environmental variation and subsequent health risks of the bacterium Vibrio parahaemolyticus among oyster consumers in the United States. Dr. Davis was awarded his Ph.D. from the Johns Hopkins Department of Environmental Health and Engineering. During his Ph.D., Dr. Davis received a certificate in risk sciences and public policy and was awarded a fellowship from the Johns Hopkins Center for a Livable Future as well as a traineeship from the National Science Foundation's Integrative Graduate Education & Research Traineeship program in Water, Climate, and Health. His previous experience also includes conducting epidemiological research at the National Institute of Aging.

Dr. Davis regularly collaborates with scientists from a broad range of disciplines, from engineers to social scientists, and has regularly interacted with federal and state risk policy managers and food industry stakeholders. He has co-authored several peer-reviewed scientific articles related to food safety and risk assessment and has presented his work at numerous scientific conferences. Dr. Davis has also been an instructor for multiple courses concerning geospatial analysis and public health.
