About Michael

Dr. Michael Lumpkin is a board-certified toxicologist with more than 20 years of experience in chemical dose response assessment, exposure assessment, dose reconstruction, chemical emergency response, risk communication, and infectious disease risk mitigation. He has led teams of environmental scientists responding to chemical accidents and industrial emissions sources to determine real-time levels of chemicals in the environment and support incident commanders and other stakeholders in understanding the associated health impacts. He has provided expert risk communication to community groups living in close proximity to petroleum faciliites, nuclear facility workers, and state and city utility and zoning boards. He has coauthored numerous peer- reviewed hazard and risk assessments for USEPA and ATSDR. He has provided critical reviews and analyses of toxicology data for numerous compounds, including PFAS, petrochemicals, formaldehyde, PAHs, perchlorates, pesticides, metals, solvents, and inhaled dust. Michael has developed, critiqued and applied PBPK models for lead, volatile organic compounds (VOCs), pesticides and bioterrorism agents for USEPA, CDC and DOD, for use in regulatory standard support and emergency planning. He has designed and performed occupational exposure reconstructions for VOCs and diisocyanates using laboratory and infield simulations. 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. He is certified as a Diplomate of the American Board of Toxicology.
