Dhimiter Bello, Sc.D., MSc, is an Associate Professor in the Department of Public Health at the University of Massachusetts, Lowell, USA. His research focuses broadly on exposure biology, an interdisciplinary approach that investigates quantitative and temporal relationships between environmental exposures and disease in humans. Exposure biology integrates critical information on the biological mechanisms of environmental exposures from diverse disciplines that study the exposure-disease continuum, including exposure sciences, molecular biology, pharmacokinetics, and mechanistic toxicology. He is actively researching two classes of chemical agents - engineered nanomaterials and reacting chemicals, such as isocyanates and epoxies - especially in high-risk industries. 

Bello’s current research interests include: i) Nanotoxicology and NanoEHS; ii) Occupational skin and inhalation toxicology, particularly around reacting chemical systems, such as isocyanates and epoxies; iii) Quantitative exposure assessment for epidemiology and intervention research, primarily in high risk industries; iv) Developing methods, platforms, and tools suitable for comprehensive physicochemical and toxicological characterization of nanoparticle exposures from nano-enabled products and other emerging technologies; and v) Investigating the utility of more biologically relevant exposure and dose metrics for inhaled nanoparticles, including surface activity and oxidative stress.

He serves as associate editor for Nanotoxicology and the Annals of Occupational Hygiene. In addition, he serves in several national and international scientific committees, including ISO. He has published over 45 peer-reviewed articles and three book chapters.
