He is broadly interested in fire science problems, utilizing experiments and theory to solve problems related to fire spread in the wildland and built environments, sustainable/green building fire safety and smoke and toxic product transport. In 2014 he started the first engineering-based wildland fire course at the University of Maryland, focusing on both the science and applications of engineering to wildland fire. He serves as Associate Editor of Fire Technology, on the editorial board of the Fire Safety Journal, a member of the NFPA Technical Committee on Wildland and Rural Fire Protection, a member of the NFPA FPRF Research Advisory Board and an elected member of the management committee of the International Association for Fire Safety Science.
