Selected Project Experience

RETRA scientists provide expert support in litigation matters involving environmental, occupational, and product-related exposures. Our team has been engaged as both testifying experts and consulting experts, offering scientific analysis and strategic guidance across a wide spectrum of claims.

Our experience spans matters involving Proposition 65, vapor intrusion, insurance claims, landfill and waste disposal sites, and PFAS. We have supported counsel with exposure reconstruction, toxicological and epidemiological evaluations, risk assessments, and causation analysis in support of complex legal disputes.

Whether serving in the role of a consulting expert to inform case strategy or as a testifying expert providing courtroom testimony, RETRA delivers objective, evidence-based insights that address chemical exposures, health risks, and regulatory compliance in the context of litigation.
