Stanford Propulsion & Space Exploration Laboratory (SPaSE)

The Stanford Propulsion & Space Exploration Laboratory (SPaSE)  studies the chemistry and physics of reactive flows relevant to advanced aerospace propulsion systems with a focus on high-speed propulsion (supersonic, hypersonic, rocketry, space entry), sustainable aviation, and compact UAS propulsion. The lab deploys scientific tools including laser and optical diagnostics, numerical modeling and simulations, and machine learning based optimization and analysis to advance our understanding of current systems and investigate next-gen technologies. Working closely with the Air Force Research Laboratory (AFRL), Army Research Laboratory (ARL), Federal Aviation Administration (FAA), Sandia National Laboratories, and Argonne National Laboratory, we pursue disruptive and sustainable propulsion concepts that can reshape our future.

Professor Lee's research group is focused on investigating the fundamental physics relevant to next generation aerospace propulsion systems and space entry technologies. Areas of interest include hypersonic propulsion systems, hybrid chemical and electrical propulsion systems, compact UAV propulsion technologies, integration of sustainable aviation fuels, and application of advanced laser & optical diagnostics. His work aims to improve fundamental understanding of high-speed reacting flows while advancing technologies for more efficient and environmentally responsible aerospace systems.
