Yingwen Cheng

Assistant Professor

Yingwen Cheng earned his Bachelor’s degrees in Chemistry and Chemical Engineering from Shandong University, China, and Ph.D. in Chemistry from Duke University. He completed his postdoctoral training at the Pacific Northwest National Laboratory and started his independent academic career at Northern Illinois University as an Assistant Professor in 2018. In 2023 he accepted a Faculty position at the University of Tennessee Knoxville and moved his group here. He is a recipient of the Doctoral New Investigator Award from the ACS Petroleum Research Fund, and was featured as an Emerging Investigator from two academic journals Nanoscale (RSC) and Energy & Fuels (ACS).

Education

B.S., Shandong University, China (2008)
Ph.D., Duke University (2013)
Postdoctoral Research Associate, Pacific Northwest National Laboratory (2017)

Research

Our research aims to develop new chemical principles to explain and control electrochemical processes for inter conversion of electrical and chemical energy. Outcomes of our work contribute to electricity-driven chemical manufacturing and storage of renewable electricity for transportation and smart power grid. We are especially interested in studying well-defined materials with systematically tunable variables to extract fundamental insights. Major topics for the near future include: 1) solid active motifs design for electrocatalytic conversion of small molecules; 2) new electrochemical interfaces for extreme batteries; 3) new ways to modulate electrochemical processes via external forces and 4) synthesis of novel nanostructures with predictable functions.
