My core research interests focus on (1) developing improved methods for energy conversion and (2) enhancing current methods of propulsion for ground-based, aviation, and space applications. My interests stem from my doctoral research on the characterization of high energy spark ignition in non-premixed flowing combustors and my post-doctoral work in liquid fuel characterization and supersonic retropropulsion. This experience in gaseous and liquid fueled combustion allows credible extension of my work into areas of gas turbine engines, internal combustion engines, and rocket propulsion. Based on my research experiences, I advocate a methodology of complementary experimental and modeling efforts, to analyze systems with many degrees of freedom and are characterized by large sets of data. This approach is especially important in energy and propulsion research, where the multi-physics and multi-scale nature of the problems necessitate the development of fundamental predictive tools, enabling enhanced performance of these complex systems.
