A scientist trained in biophysical chemistry, this expert has more than 40 years of experience in chemical toxicology, mutagenesis, and carcinogenesis, investigating the molecular and cellular pathways through which toxic chemicals, including metals, asbestos, and polycyclic aromatic hydrocarbons, induce genetic damage and cancer. The expert’s areas of expertise include heavy metal toxicology and carcinogenesis, polycyclic aromatic hydrocarbon toxicology, asbestos and inorganic elements carcinogenesis, environmental carcinogenesis, environmental pollution, human toxicology, human carcinogenesis, and genetic toxicology. The expert has experience in cases involving asbestos-induced lung injury, heavy metal toxicity, and chemically induced lung cancer, and has more than 30 years of expert witness experience, including consultation, deposition, and courtroom testimony. The expert does not provide opinions in blood alcohol testing, drug testing, mold exposure, or marijuana-related matters.

The expert’s research focuses on the molecular and cellular mechanisms of chemical carcinogenesis, including the study of carcinogenic metal compounds such as nickel and chromium and the roles these compounds play in cytotoxicity, genotoxicity, chromosomal aberrations, proto-oncogene activation, tumor suppressor gene inactivation, and transformation of mammalian cells. The expert has held academic appointments as Associate Professor of Molecular Microbiology and Immunology, Pathology, and Molecular Pharmacology and Pharmaceutical Sciences, and has served as Faculty Supervisor of a molecular and cell biology support core laboratory within a comprehensive cancer center. The expert has participated in scientific advisory and review panels for federal and state agencies addressing carcinogen identification, toxic air contaminants, drinking water safety, and environmental health research. The expert holds a Ph.D. in Biophysical Chemistry and completed postdoctoral training in the molecular biology of chemical carcinogenesis. In addition to toxicology consulting, the expert also provides consultation in intellectual property matters involving biology and chemistry.
