Biography

Dr. Dotson is a Senior Managing Health Scientist with Cardno ChemRisk. His principal areas of training and expertise include toxicology, industrial hygiene, risk assessment, and occupational health. He is actively engaged in efforts related to antimicrobial agents (such as surface disinfectants), inhalation toxicology of aerosols, development of occupational exposure limits (OELs), indoor environmental quality (IEQ) assessments, and the designing and implementation of risk management strategies.

Dr. Dotson obtained a M.S. from Murray State University in Occupational Safety and Health with an emphasis in industrial hygiene and a Ph.D. in toxicology and risk assessment from the University of South Florida. His doctoral research focused on quantifying workplace exposures and health risks associated with the servicing of asbestos-containing automotive parts and materials. He is a certified industrial hygienist (CIH) and is a Diplomate of the American Board of Toxicology (DABT).

Prior to joining Cardno ChemRisk, Dr. Dotson was employed by the Centers for Disease Control and Prevention, National Institute for Occupational Safety and Health (NIOSH) as a health scientist for over 10 years. His research efforts and responsibilities focused on critically evaluating occupational hazards and developing appropriate guidelines used to establish NIOSH policies, scientific-decision making strategies, and recommendations. As part of these efforts, he conducted assessments aimed at characterizing the hazard and risk associated with dermal contact to chemicals, developed workplace recommendations to protect workers from acute inhalation exposures, and investigated the integration of novel risk assessment methods into occupational health. Dr. Dotson also led NIOSH projects focused on investigating the health risks of workplace exposures to 1-bromopropane and peracetic acid.

He is active in multiple professional organization, such as the American Industrial Hygiene Association (AIHA), Society for Risk Analysis (SRA), and Society of Toxicology (SOT). Dr. Dotson has served as an officer of the AIHA Risk Committee and SRA Occupational Health and Safety Specialty Section.
