Professor C.K. Law hosted the 7th Princeton Summer School on Combustion from June 19th to 24th. A total of 225 senior graduate students and researchers from all over the States and some overseas countries attended. The Summer School offered five courses, each taught over five days of three hours of lecture per day. The lecturers (and courses) were Prof. Henry Curran of the University of Ireland at Galway (on combustion chemistry), Prof. Mark Linne of the University of Edinburgh (on laser diagnostics), Prof. Jim Driscoll of the University of Michigan and incoming president of the Combustion Institute (on turbulent combustion), Prof. Sebastien Candel of Ecole Central Paris and incoming president of the French Academy of Sciences (on unsteady combustion), and Prof. Law (on combustion physics). The Summer School was sponsored by DOE, the Combustion Institute and Princeton University, with additional support from ARO, NSF and KAUST. It has become a major event in the combustion community, aiming to facilitate the training of next-generation of combustion researchers who are knowledgeable in both combustion physics and chemistry, and in both the fundamentals and applications, and has also become the model recently adopted by the Combustion Institute in setting up similar summer/winter schools in other parts of the world.
