Asst Prof Tej S. Choksi
Assistant Professor, School of Chemistry, Chemical Engineering and Biotechnology
Tej Choksi received his Bachelors in Chemical Engineering from the Institute of Chemical Technology, Mumbai, India in 2012. He then obtained his PhD in Chemical Engineering from Purdue University, West Lafayette in December 2017. His dissertation research, under the guidance of Professor Jeffrey Greeley, focused on first principles studies of reducible oxides and metal/oxide interfacial catalysts. He then obtained postdoctoral research experience at Stanford University at the SUNCAT Centre for Interface Science and Catalysts under the supervision of Dr. Frank Abild-Pedersen. During his postdoc, he helped develop the alloy stability model, a unified framework for determining the stability and reactivity of alloy nanoparticles with active site precision. He started his independent scientific career in December 2019. He is also a co-Investigator at the Cambridge Centre for Advanced Research and Education in Singapore. Tej is a fellow of the Renaissance Engineering Programme, NTU’s flagship engineering programme for nurturing next-generation leaders and entrepreneurs. Tej is the Vice President of the Singapore Catalysis Society.
Our research group employs first principles calculations, statistical thermodynamics, and kinetic modelling to understand how catalysts work at the atomic scale. We employ a combination of data-driven and physics-based techniques to:

-identify the active site and reaction mechanism
-determine the catalyst structure under reaction conditions
-establish computational workflows for screening catalysts
-design new candidate catalysts using these computational workflows

Our group aims to discover new catalysts which will steer Singapore's transition into a sustainable economy. Our catalyst design efforts are focused on CO2 utilization, green hydrogen generation, and transforming biomass into fuels and chemicals.
