Bohak Yoon

Postdoctoral Scholar
Department of Chemistry
The University of Chicago

Bohak received his B.S. and Ph.D. in 2016 and 2022, respectively, both in Chemical Engineering. During his Ph.D. at the University of Texas at Austin, he worked on first-principles studies on thermal and oxidative degradation and corrosion of aqueous amine solvents for carbon dioxide capture using ab initio molecular dynamics with advanced sampling methods. Bohak joined the Voth group as a postdoctoral scholar in July 2022. His research interests are in the multiscale theory and simulation of ionic liquids and other aqueous systems pertinent to alternative energy, new materials, and separations.
