Christopher Douglas

Bio

Christopher Douglas' research focuses on fluid and thermal sciences, with an emphasis on flow instability, combustion dynamics, and thermoacoustics. In his work, he develops theoretical and numerical methods to analyze, understand, and control the behavior of high-dimensional nonlinear systems encountered in engineering applications including turbines, rockets, and other energy systems, as well as in diverse natural phenomena such as atmospheric mixing and supernovae. His broader research interests include energy decarbonization and pollutant emissions abatement, with particular attention to alternative energy carriers like hydrogen and ammonia.

Christopher is actively seeking graduate students and postdocs for the 2025 calendar year. If interested, please reach out via email and include your CV and a cover letter explaining your past and future interests.
