Kai graduated with a Bachelor of Engineering (Environmental) with Honours from the Nanyang Technological University. His undergraduate research experience included operating a reverse osmosis desalination system for a pilot study and designing spacer configurations to enhance mass transfer in membrane processes. He went on to pursue a Ph.D. degree in Chemical Engineering at The Ohio State University. His graduate research focused on developing membranes with amine-containing polymers for CO2 capture from power plant flue gas and fuel cell exhaust, respectively. Besides polymer synthesis and characterizations, Kai also had experience in scale-up production of flat-sheet membranes and fabrication of spiral-wound membrane modules for carbon capture field tests.
Before joining Spruson & Ferguson, Kai worked briefly as a Research Fellow at NTU, where he investigated membrane fouling in the forward osmosis process using optical coherence tomography.
