Dr. Geunho Han received his Ph.D. in Chemical and Biological Engineering from Korea University under the supervision of Prof. Kwan-Young Lee, where he also earned his B.S. degree in the same field. After a brief period as a postdoctoral researcher and research professor at Korea University, he continued his academic career at Northwestern University, working with Prof. Justin Notestein on advanced nanocatalysts for tandem catalysis. His doctoral research contributed to various areas in catalysis, including biomass conversion, natural gas reforming, eco-friendly direct hydrogen peroxide synthesis, and nano-catalyst design. During his postdoctoral studies, he focused on developing novel catalytic materials for more demanding tandem reactions, employing atomic layer deposition (ALD) to fabricate heterogeneous catalysts for oxidative hydrocarbon dehydrogenation. Dr. Han is currently an advanced R&D scientist at Honeywell UOP, where he works on the Fundamental Catalysis and Application team.
