# overview
As a professor in the Department of Soil and Crop Sciences and member of the Interdisciplinary Faculty of Toxicology and Food Science graduate faculty, I direct a graduate education and outreach program and conduct research in regulatory science. I also serves as the State Chemist and Director of the Office of the Texas State Chemist (OTSC). In my dual role of educator and regulator, I work with students, faculty, university administrators, state and federal regulators, legislators, and manufacturers, distributors, and consumers of feed and fertilizer. A focus of my research and outreach activities involves public-private partnerships to manage mycotoxin risk through co-regulation. This effort is supported through an ISO accredited aflatoxin proficiency testing program delivered to over 200 labs in 62 countries - operating as APTECA.
