I have 37 years of experience, and specialize in the field of veterinary toxicology with specific knowledge in the areas of nitrate and nitrite pathophysiology, mycotoxins, and cyclotrimethylenetrinitramine (RDX). I have published on such topics as nitrate and nitrite pharmacokinetics and pathophysiology, effects of mycotoxins on domestic animals, and metabolism of cyclotrimethylenetrinitramine. I have testified on polychlorinated biphenyls (PCBs), chronic nitrate poisoning and chlorate poisoning.
