Songhyun Lee

Henson Postdoctoral Research Fellow

Advised by Professor Rajamani Gounder




Background

I joined the Gounder Group in the fall of 2020. My research involves the synthesis of zeolites with controlled framework and extraframework active site distributions, and studying their consequences for acid and metal-catalyzed reaction rates and selectivities. I obtained my PhD in chemical and biomolecular engineering with Minkee Choi at KAIST, where my research focused on designing advanced solid acid and metal catalysts by elucidating the structure-property relationships that govern selectivity and lifetime. In my free time, I enjoy playing badminton, swimming, and watching movies.
