Mr. Aiosa represents clients in large, complex, domestic and international litigation – state and federal class actions, multidistrict litigation, appeals, and foreign tribunals, including matters involving military, commercial/agricultural, and consumer products, and employment discrimination claims.

He has served as lead coordinating counsel for Fortune 100 companies in a wide range of complex litigation involving employment discrimination, environmental contaminants, chemical exposures, herbicides, pesticides, and fungicides, and other compounds considered persistent, bioaccumulative and toxic.

Mr. Aiosa has also represented large commercial insurance companies in contract disputes and coverage litigation, including environmental, product liability, property damage, and toxic tort matters involving PCBs, TCE, asbestos and tobacco, and employment discrimination class action claims.

He has extensive experience litigating a range of complex disputes, including mass tort and class action product liability actions—foreign and domestic—involving military, consumer and commercial/agricultural products containing dioxins and furans, hexachlorobenzene (HCB), pentachlorophenol (PCP), arsenic, cacodylic acid, and other organic arsenicals. Mr. Aiosa has defended chemical product manufacturers against claims involving cancers, endocrine-related disorders, neurological complaints, neurodevelopmental deficiencies and other alleged multi-generational effects, pulmonary and cardiovascular diseases, diabetes, fear of future diseases and medical monitoring.

Mr. Aiosa has led the development of his clients’ medical and scientific defenses and trial strategies, working closely with top-tier scientists, clinicians, regulatory experts, and government affairs advisors, to optimize principles of toxicology, epidemiology, risk assessment, biostatistics, and regulatory policy, for deployment inside and outside the courtroom. He also has deep experience addressing the range of procedural/jurisdictional features frequently presented by such complex litigation, particularly those venued internationally—from pre-suit through resolution—enabling him to leverage those features to his clients’ advantage.

He previously held the position of Queens County Assistant District Attorney.
