The Burgers Program and Combustion Institute Summer School on Fire Safety Science – Wildland/WUI Fire Behavior will bring together graduate students, post-doctoral fellows, and early-career researchers and engineers, engaged in fire science, as well as distinguished instructors from leading higher-education institutions and research programs in fire safety around the world. The summer school will be held on the University of Maryland campus during the week of 5-9 June 2023. The program will be focused on the behavior of wildland fires and Wildland-Urban-Interface (WUI) fires and will adopt a viewpoint that is primarily (but not exclusively) engineering-based. The objectives of the summer school are to expose participants to a broad range of advanced topics relevant to wildland and WUI fires with a mix between fundamental courses that emphasize the underlying physical and chemical mechanisms and general courses that describe the scope of the real-world problem and emphasize current challenges in finding solutions to mitigate the negative impacts of large outdoor fires. The objectives are also to build a strong international network of graduate students, post-doctoral fellows, early-career researchers and engineers, instructors and leading researchers.
