This researcher works on control theory for engineering systems, focusing on how to determine and guarantee the stability of dynamic systems (such as aircraft, satellites, microgrids, and mechanical drivetrains) without relying solely on traditional eigenvalue-based methods. Much of the recent work develops alternative mathematical tools, termed 'convex stability' and 'transformation allergic indices,' intended to give more reliable stability guarantees for control system design in applications like satellite attitude control, aircraft autopilots, and power grids.
Publication output was intermittent from 2019-2023 with several low or zero-output years, but has increased notably in 2024-2025, suggesting renewed and active research activity.
