Dr. Demokritou’s research interests are primarily in the areas of aerosol science and technology and particle health effects. His current research focuses on the applications and environmental health and safety implications of engineered nanomaterials and nanotechnology in general. Dr. Demokritou has been one of the PI’s of the Harvard/US EPA Center for Ambient Particle Health Effects and participated in many international Particle Health Effect field studies (US, Chile, Finland, Greece, Kuwait, Cyprus). Dr. Demokritou and his team have developed over the years many instruments and patented methods focusing on the physico-chemical and biological characterization of particles. These novel techniques have been used extensively by human exposure assessors in United States and worldwide and have helped to advance the field of particle health effects. He is a co-author of two books, numerous book chapters, and articles in leading journals in the particle health effect and aerosol engineering fields. Dr. Demokritou is currently an Associate Professor at Harvard T.H. Chan School of Public Health and the Director of the Environmental Health Nanoscience Laboratory and the Center for Nanotechnology and Nanotoxicology at the Harvard T.H. Chan School of Public Health.
