He has extensive experience with the Federal Insecticide, Fungicide, and Rodenticide Act, particularly with respect to regulation of antimicrobials, and with the Biocidal Products Directive in Europe.

He heads the Firm’s FDA practice, having worked on FDA regulation of food and food additives, dietary supplements, drugs, medical devices, and cosmetics, and European counterparts.  He is knowledgeable about human testing requirements, having served as the Chair of an institutional review board for several years.

He has counseled clients on the regulation of consumer products by the Consumer Product Safety Commission and the Federal Trade Commission.  He has reviewed hundreds of green marketing claims and counseled on federal, state, and international regulation of such claims.

He has worked on green chemistry issues at the federal and state levels, as well as a variety of voluntary programs that affect products.  He has helped clients with the Emergency Planning and Community Right-to-Know Act, the Controlled Substances Act, the Chemical Weapons Convention, and other chemicals-related requirements.

He has advised clients and written and lectured on regulation of the products of nanotechnology by FDA and by EPA under FIFRA and TSCA, and on related product stewardship issues.
