Haiying Chen

Bio

Dr. Hai-Ying Chen is a distinguished R&D staff member at Oak Ridge National Laboratory (ORNL). His research interests are in advancing catalysis science and technologies to enable both mobile source and stationary source exhausts to meet near-zero pollutant emission regulations, and in developing energy-efficient catalytic processes to accelerate the decarbonization of sectors that are difficult to electrify.

Before joining ORNL in April 2021, Dr. Chen was a global technology fellow at Johnson Matthey Inc., with more than 21 years of industrial catalysis experience in exhaust emission control technologies.

Dr. Chen holds more than 400 granted patents in various jurisdictions around the world. His work has led to the successful commercialization of a full spectrum of emission control catalysts, including advanced three-way catalysts for gasoline vehicles to meet the US Environmental Protection Agency Super Ultra-Low Emission Vehicle standards; the first NO_x adsorber catalyst system for heavy-duty diesel trucks to meet the US Environmental Protection Agency 2010 heavy-duty diesel emission regulations 3 years ahead of schedule; and small-pore zeolite-based selective catalytic reduction catalysts that enable diesel engines to reach near-zero pollutant emissions. These technologies have prevented hundreds of million tons of air pollutants from emitting into the atmosphere.
