Diego’s SURP application, titled “Design of a 2-inch Diameter Rotating Detonation Engine”, was selected by the Faculty Advisory Board as one of the top Engineering SURP proposals. In recognition of this distinction, he has been awarded the Philip S. Hiestand Engineering Research Award.
Thomas presents a paper titled “Lean detonability of hydrogen-oxygen mixtures in narrow channels”.
Brian presents a paper titled “Propagation limits of cellular detonation in narrow channels”.
Rio presents a paper titled “Optimizing nanographene formation in natural gas pyrolysis via microwave plasma”.
Thomas was awarded the Melucci Endowed Fellowship for Spring 2025. The Melucci Endowed Fellowship was created to support and enhance the education of UC Irvine graduate students working in space exploration and space technology. Past recipients have worked on the Rover guidance system for landing on Mars, electric propulsion for space craft, as well as people looking at combustion and structures.
Thomas and Spencer serve as mentors for the 2024 NASA Community College Aerospace Scholars (NCAS) program jointly hosted by Orange Coast College and South Western College, where they guided teams in building robots for a simulated NASA contract competition for the exploration of Mars. The teams also toured our research lab to share the opportunities available once they transfer to a four-year college. Thomas’ team won the competition with their excellent robot construction, teamwork, and competition presentation.
Spencer receives the GAANN Fellowship from the MAE department, a US DoEd Graduate Assistance in Areas of National Need grant. Congratulations, Spencer!
Xian presents a paper based on his collaboration with Professor Sirignano, titled “Three-dimensional rotational flameLet (3D-RFL) with detailed chemistry and transport models”.
In addition, Xian attends and helps organize the 2023 Combustion Early Career Investigator Workshop.
Xian Shi joins the Department of Mechanical and Aerospace Engineering at the University of California, Irvine as an Assistant Professor.
