I have over 20 years of experience as a researcher, principal investigator, and consultant in public health with a focus on environmental and occupational health, epidemiology, and toxicology. I authored over 30 peer-reviewed publications in environmental and occupational health and epidemiology. My PhD and later work heavily focused on environmental and occupational studies, assessing human exposures to chemical mixtures and their link to health outcomes. I designed and directed population-based studies, including roofers, welders, coke oven workers, and Air Force personnel. Over the last few years, I have been an expert witness in legal cases evaluating toxic exposures, reviewing existing literature, and preparing reports. For example, I recently prepared a report summarizing my findings on the link between glyphosate exposures and the risk of non-Hodgkin’s lymphoma. Some examples of the chemical mixtures I worked on are: - Pesticides, Herbicides - Camp Lejeune Water Contamination...
