Andrew Barnabas WONG

Dr. Andrew B. Wong is a Presidential Young Professor in the Department of Materials Science and Engineering. He also holds a joint appointment in the Department of Chemical and Biomolecular Engineering at NUS. Originally from Buffalo, New York, USA, he received a joint BS-MS degree in Chemistry from the University of Chicago in 2011. Following that, he received his PhD in Chemistry from UC Berkeley in 2016 under Prof. Peidong Yang. Subsequently, he was a postdoctoral researcher at Stanford University, where he was co-advised by Thomas Jaramillo and James Harris. He has significant expertise in nanoscale, optoelectronic, and electrocatalytic materials.

Research Interests

His current research focuses on fundamental understanding and developing control of the local environment for electrochemical CO₂ conversion. His research also explores emerging strategies to valorize CO₂ inspired by these insights. For the electrochemical CO₂ reduction reaction (CO₂RR), these topics include developing new innovations in:

• Fundamental Understanding of CO₂RR
• New Materials to Tune the Local (Micro)environment to Improve CO₂RR Selectivity
• Bicarbonate reduction to valorize CO₂
• Molten salt electrolytes for CO₂RR to Carbon Nanomaterials
• Bioelectrochemical CO₂RR
