Expertise DescriptionI have more than 30 years experience in the field of Occupational Medicine with expertise in air pollution effects and community risk, ecosystem and human health, energy industries and their occupational and environmental health risks, environmental quality, environmental toxicology, ecosystem health, and relation to human health. I have additional knowledge in firefighters and occupational risk, inhalation toxicology and occupational lung diseases, occupational cancer, and pulmonary injury from and response to inhaled particles. I have over 30 years expert witness experience with consultations, deposition, and courtroom testimony.
Areas of Expertise
My professional experience includes being Vice President of Health/Safety/Environmental and Sustainability department, as well as Research Professor, Adjunct Faculty, and Professor of Occupational and Environmental Medicine.
My primary interest in toxicology is occupational exposure and inhalation toxicology. I have had some experience with anesthetic gases as medical director of a hospital. I am familiar with isoflurane primarily as an anesthetic gas which has a reputation for relative safety but which still requires workplace controls and protection. The literature on isoflurane is primarily from animal experimentation and indicates some potential risk of neurological complications; lung effects are not front and center. In special applications (emulsified administration) isoflurane appears to be protective against cardiovascular inflammation. Human studies generally show safe use for surgery during pregnancy. My approach would therefore be to review the circumstances of exposure (how much it exceeded standards), when it occurred during gestation, and what kind of lung disease the child sustained. If the condition is pediatric respiratory distress syndrome, a case might be made that maturation of the lung had been delayed causing underdevelopment at birth. Also important would be to understand whether nitrous oxide was used in the same veterinary workplace together with isoflurane. Where we would go from there depends on the specific facts of the case. For this reason, I would need to do a “merit review” of the medical records and a literature review for general causation before committing to be declared as an expert witness in the case.
