Andrew Barnabas Wong

Assistant Professor Andrew Barnabas Wong holds a primary appointment in the Department of Materials Science and Engineering at the National University of Singapore (NUS), with a joint affiliation in the Department of Chemical and Biomolecular Engineering. His research program focuses on advancing electrochemical CO₂ conversion technologies for sustainable energy applications.

His academic training includes:

• Joint B.S.-M.S. in Chemistry, University of Chicago (2011)
• Ph.D. in Chemistry, UC Berkeley under Prof. Peidong Yang (2016)
• Postdoctoral research with Prof. Thomas Jaramillo at Stanford University (2016-2020)

Dr. Wong's research centers on engineering electrochemical microenvironments through three interconnected thrusts: (1) developing materials and methods to optimize CO₂ reduction reaction (CO₂RR) microenvironments, (2) pioneering high-temperature CO₂ conversion in molten salt electrolytes to circumvent hydrogen evolution limitations, and (3) creating hybrid biotic-abiotic systems that combine electrocatalysis with microbial catalysis for challenging reactions like N₂ reduction. His group also develops perovskite-inspired materials for defect-tolerant semiconductors.

Analysis of his 15 most recent publications (2018-2025) reveals consistent focus on microenvironment engineering for CO₂ conversion, with significant contributions in interfacial structure control, CO transport management, and novel catalyst-electrolyte design. His work bridges electrocatalysis, materials science, and bioelectrochemistry, demonstrating particular expertise in tandem catalytic systems and molten electrolyte approaches for multicarbon product generation.

Dr. Wong leads the A.B. Wong Group at NUS, which maintains active collaborations across chemistry, materials science, and chemical engineering disciplines. The group's facilities in Engineering Block 2 (E2-05-26) support research in rational material synthesis and electrochemical conversion systems development.
