Postdoctoral Researchers

JunSong Kim

I am a postdoctoral associate in the Department of Earth Sciences at the University of Minnesota. I earned my Ph.D. in 2018 from Seoul National University, where I conducted numerical modeling and field experiments for understanding and predicting the dynamics of harmful algal bloom in regulated rivers. Currently, I am conducting PIV experiments at SAFL and also performing direct numerical simulations to understand mass transfer and mixing mechanisms at fluid-porous media interfaces.

SangHyun Lee

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 both experimental (microfluidics) and modeling (COMSOL Multi-physics) studies to advance our fundamental understanding on the interplay among 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 the formation of bacterial biofilms. In addition, I am also conducting microfluidic experiments to understand how the interplay between fracture roughness and flow rate controls mixing and reaction kinetics at fracture intersections. 

SeonKyoo Yoon

I am a postdoctoral associate in the Department of Earth Sciences at the University of Minnesota, Twin Cities. I received my Ph.D. from Massachusetts Institute of Technology in 2016. My PhD thesis was on developing computationally efficient subsurface flow models and inverse modeling methods to characterize hydrogeological parameters. My research centers on model-data fusion, combining process-based models with data-driven methods, to improve predictive capability and understanding of hydrogeological systems. I am currently working on inverse problems for subsurface characterization and anomalous transport in fractured media.


Graduate Students

WoongHee Lee

I am a Ph.D. student in the Department of Earth Sciences at the University of Minnesota. I obtained my M.S. degree jointly from Korea University and Korea Institute of Science and Technology (KIST) in 2017. My M.S. thesis (co-advised by Prof. Kang) was on pore-sale modeling of forward osmosis processes which led to two journal publications. I also conducted field-scale reactive transport modeling of a river bank filtration site as a research assistant at KIST for a year after obtaining my M.S. degree. My research interest is in reactive transport modeling in geologic fractured media. I am currently studying mixing and reaction at fracture intersections with direct numerical simulations. I am also involved in a NSF project where I collaborate with geobiologists and geochemists to understand the mechanisms by which microbial activity interacts with physical and geochemical components of the subsurface to create feedbacks for habitability in permanently anoxic, fractured-rock systems.
