Dr. Dilpreet Singh is a Senior Scientist in the Health Sciences practice at Exponent, where he provides consulting services in the area of quantitative exposure assessment and risk modeling of consumer products and occupational environments involving use of emerging chemicals and advanced materials including nanoparticles.

Dr. Singh specializes in the design and development of lab-based platforms and approaches for assessing lifecycle-specific exposures to engineered nanomaterials and incidental nanoparticles in occupational, consumer product use and environmental settings. During his recent doctoral and postdoctoral research at the Harvard T.H. Chan School of Public Health, Dr. Singh performed extensive physicochemical, morphological and toxicological characterization of engineered nanomaterial exposures from nano-enabled consumer and industrial products across different relevant lifecycle degradation scenarios including end-of-life processes such as incineration. In addition, Dr. Singh has also conducted numerous studies involving exposure characterization and toxicological evaluation of incidental and environmental nanoparticles such as those generated from toner-based photocopiers and laser printers, vaping of electronic cigarette devices with different e-liquids and operational voltages, and burning of hardwoods and softwoods under different combustion conditions in wood stoves and wildfires.

Dr. Singh is a co-author of 20+ peer-reviewed publications in the field of nanotechnology health and safety in high-impact journals and is a recipient of the New Investigator Award from the U.S. National Nanotechnology Initiative (NNI) and the Consumer Product Safety Commission (CPSC). Dr. Singh is a part-time instructor at Harvard University for the “New Developments in Nanotechnology” module of the annual executive course on "Comprehensive Industrial Hygiene". Dr. Singh holds an Sc.D. in Environmental Health from Harvard University with specialization in bioengineering, exposure assessment and toxicology, an M.S. in Environmental Engineering from the University of Southern California (USC) with focus on water and wastewater treatment technologies, and a B.Tech. in Civil Engineering from the Indian Institute of Technology (IIT), New Delhi.
