Research Interests:

My research interests focus on the kinetics and reliability in the thermo-electro-chemical processes under extremely-harsh operating conditions, e.g., high temperature/pressure (depending on the materials), supercritical conditions, and corrosive and radioactive environment for combustion, advanced energy conversion and chemical production. My lab will aim at investigating the reacting flows under these harsh conditions in energy conversion systems, drawing on the operando experimental methods. We will also explore numerical methods to study the relationship between the performance and economics on a system-scaled level. We will then apply the understanding about kinetics to avoid performance degradation and improve reliability. My personal aim is to closely collaborate with scientists and industrial partners to develop the scientific findings in my lab into engineering applications in industry.

My experience in high-temperature heterogeneous reactions, electrochemical reactions and enhanced heat transfer has motivated the following proposed research topics. Two topics on membrane-supported H2O/CO2 to value-added chemicals and supercritical hydrocarbon pyrolysis regenerative cooling are developed from my previous research topics. And two other topics, (i.e., ultra-lean methane utilization and sensing in harsh environments) are under development to be my future directions.

Teaching Interests:

I am planning to teach courses in the fields of thermodynamics, transport theory, separation, chemical kinetics.
