I have 30 years of experience, and specialize in the field of pharmacology with specific knowledge in the areas of dermal drug delivery, chemical food residues and pharmacokinetics. I have published on such topics as dermal drug delivery and safety, mixture toxicology, predicting chemical residues and nanomaterial biodistribution. My work bridges the fields of human and animal pharmacology and toxicology which gives me unique perspectives on extrapolation between animal tests and human hazard.
