Electrified Thermochemical Systems for Scalable Chemical Manufacturing


I design electrified catalytic reactor systems that enable rapid thermal modulation, selective energy delivery, and scalable process intensification. My research integrates catalyst design, reactor engineering, and power electronics to control reaction energetics beyond conventional thermal limits.
Rapid Pulsed Joule Heating and Tandem Chemistry
We establish resistively heated catalytic reactors as platforms for millisecond-scale temperature modulation and dynamic kinetic control. By directly coupling electrical power to the catalyst bed, we decouple thermal inertia from reactor mass and enable extreme temperature ramping beyond furnace limitations.

Microwave-assisted Thermal Catalysis and Defect-driven Redox Kinetics
We investigate energy coupling under microwave excitation to probe whether reaction kinetics can be modulated beyond bulk thermal effects. By integrating cavity engineering with in situ diagnostics, we study field–defect interactions and polarization-dependent reactivity in catalytic solids.

Scalable Hydrogen Release Systems and Low-Pt Dehydrogenation Catalysts
We develop integrated catalyst–reactor platforms for efficient hydrogen release from liquid organic carriers and ammonia. By combining catalyst design, heat management, and scale-up strategy, we bridge fundamental reaction engineering with deployable hydrogen infrastructure.
