He has developed novel occupational exposure limits for pharmaceutical and industrial chemicals. Michael has served on ad hoc federal grant review committees and as a peer reviewer for toxicology journals, and has lectured in graduate courses and emergency responder seminars for inhalation toxicology and risk assessment.
