Dr. Holbrook received the PECASE Award for establishing himself as an internationally recognized leader in measurements and analysis of environmental fate and impact of nano-scale material and nanoparticles. Applying NIST's advanced measurement techniques and analytical methodologies in combination with his wastewater treatment process engineering, environmental toxicology and chemical engineering expertise, Dr. Holbrook developed an environmental model system of the freshwater food to study trophic transfer of nanoparticles among freshwater organisms.
