I have 40 years of experience and specialize in the field of biochemistry with specific knowledge in the areas of neurodegenerative diseases, bioactivation (toxification) of foreign substances including halogenated compounds and metabolism. I have published on such topics as mechanisms of neurodgeneration, bioactivation of halogenated environmental toxicants and general areas of nitrogen, sulfur and energy metabolism. I have a broad knowledge of biochemistry and enzymology and their application to toxicology, pharmacology and disease.
