BIOGRAPHY

Jai Hyun Koh is a Kwanjeong Educational Foundation Fellow and a Ph.D. candidate at the University of Texas at Austin. He graduated from Seoul National University (SNU) with a M.S. and a B.S. in Chemical and Biological Engineering. While at SNU, he conducted research under Dr. Kookheon Char on developing soft lithographic techniques for biomimetic water-repelling surfaces. After graduation, Jai Hyun worked as a research scientist at Korea Institute of Science and Technology (KIST) where he investigated catalytic materials for electrochemical CO2 reduction. In 2016, he moved to the University of Texas at Austin to pursue a Ph.D. degree in Chemical Engineering. He is co-advised by Dr. C. Grant Willson and Dr. Nathaniel A. Lynd. Jai Hyun is currently working on the synthesis of silicon-containing block copolymers and their applications in lithography and polymer electrolyte membranes.

EXPERIENCE

Willson Group & Lynd Group at the University of Texas at Austin (Aug 2016–present)
McKetta Department of Chemical Engineering
Ph.D. Candidate and Kwanjeong Educational Foundation Fellow
Polymer Chemistry and Nanolithography
– Designed and synthesized high-χ block copolymers (BCPs) for directed self-assembly (DSA)
– Explored the dependence of Tof styrene-based statistical copolymers on monomer compositions to enable orientation control of high-TBCPs only with thermal annealing
– Investigated the origin of pattern defects in the DSA of Si-containing BCPs by evaluating defect densities upon doping of small molecules
– Developed a purification method for BCPs and achieved a significantly lower defect density in line-and-space patterns in collaboration with imec (Belgium)
– Developed polymer brushes with the chemical selectivity necessary to control interfacial energies at the bottom interfaces of BCPs for defect reduction in the DSA

Korea Institute of Science and Technology (KIST) (Feb 2013–Jul 2016)
Clean Energy Research Center
Research Scientist/Staff (selected as one of ten from across Korea to fulfill mandatory military service at KIST)
Electrocatalysis and Synthesis/Characterization of Catalytic Nanomaterials
– Synthesized various metal-based catalytic nanomaterials for electrochemical CO2reduction to hydrocarbons (e.g.,CO, HCOOH, CH4, etc.)
– Set up analytical systems for the quantification of products from electrochemical CO2reduction: on-line gas chromatography for gas products and 1H NMR for liquid products
– Developed a two-compartment electrochemical cell for in-situ measurement of gas production rates
– Participated in the development of a photovoltaic–electrochemical (PV–EC) CO2conversion system with CIGS module, Co3O4nano-catalysts, and Au-based nano-catalysts

Char Group at Seoul National University (Mar 2011–Jan 2013)
School of Chemical and Biological Engineering
Graduate Researcher (M.S.)
Polymer Processing and Soft Lithography
– Developed soft lithography techniques for the fabrication of multiscale surfaces with inorganic nanoparticles using UV-curable polymers
– Fabricated biomimetic water-repelling hierarchical surfaces by soft lithography and investigated the dependence of surface wettability on the geometry of the surface
