Travis Kline is a Senior Principal Toxicologist based in Washington, D.C. with more than 25 years of experience focused on human health risk assessment and applied toxicology.


A board-certified environmental toxicologist, Travis has experience in litigation support developing novel approaches and solutions to the characterization of problematic exposures. His recent focus has been on risk-driven advocacy and allocation support at large, multi-Potentially Responsible Party (PRP) Superfund sites in Oregon Washington, New York, and New Jersey.

Travis is the lead author of a 2019 health-mediated cost allocation strategy for a large multi-PRP coastal riverine sediment site in the eastern U.S, addressing carcinogenic PAHs, dioxin/furans, PCBs, and toxic heavy metals. Travis is actively engaged in emerging constituent issues and is leading characterization efforts and developing positions for negotiations with the administrative authorities at multiple PFAS sites with national significance in Delaware, New York, Virginia, and North Carolina. He has authored, provided expert peer review, and chaired development working groups for state and federal risk assessment guidance development, statutes and rules. He was Chair of the external review of USEPA's Human Health Risk Assessment Protocol for Hazardous Waste Combustion Facilities. As an invited lecturer for continuing education (CLE) classes on behalf of the American Bar Association (ABA), he has instructed on risk-mediated topics, such as factoring toxicity into cost allocation. Travis is Chair of the ABA's Science & Technology Committee.

Travis has extensive expertise in vapor intrusion assessment and is active on investigations surrounding problematic constituents (e.g., subchronic inhalation exposure to TCE). Travis consults with specialty chemical manufacturers to address TCSA requirements, product development challenges, pesticide registrations under federal and state programs (e.g., FIFRA) and data gap assessments, with specialized expertise in plasticizer and phthalate exposure, focusing on endocrine disruption and reproductive/developmental endpoint assessment. Travis is also active on consumer product safety assessments, including Prop. 65 hazard assessments, SDS development, and product stewardship services (e.g., Hazard and Safety Assessments, Regulatory Review, GSH Classification, CPSC labeling). Travis authored the first state- or federally-promulgated Alternative Assessment Report for bisphenol-A and his work on behalf of Eastman Chemical Company to clarify neurotoxicological implications and respiratory sensitization for a non-orthophthalate plasticizer was nominated for a Presidential Green Chemistry Award.
