I am a postdoctoral associate in the Department of Earth Sciences at the University of Minnesota. I received my Ph.D. from Seoul National University in 2017 and worked as a postdoctoral researcher at Korea Institute of Sciecnce and Technology (KIST) before joining U of MN in 2018. I combine experimental (microfluidics) and numerical modeling to advance our fundamental understanding of the interplay between biological, physical, and chemical processes taking place in porous and fractured media. Especially, I am interested in the effects of surface roughness on flow fields and its subsequent consequences on mixing, reaction, and biofilm formation. I am currently conducting microfluidic experiments to understand how fracture roughness and flow rate control mixing, reaction, and biofilm formation in fractured media.
