Sunghoon Kim, PhD / Founder

Sunghoon Kim, PhD / Founder of Excubio Pharmaceuticals Inc. & Biocon Research Director

Professor, College of Pharmacy and Director, Medicinal Bioconvergence Research Center (“Biocon”), Seoul National University 

Prof. Kim’s  research has focused on  unveiling novel regulatory networks mediated by human aminoacyl-tRNA synthetases (ARSs). This family of enzymes has traditionally been regarded as housekeeping machinery for protein synthesis. The regulatory roles and implications of these proteins in human diseases have been largely overlooked for decades. Prof. Kim’s discoveries on the new function, pathology and medicine of ARSs are rapidly opening a research area that casts new insights into the central dogma of life and human diseases.  

Prof. Kim’s contributions were recognized by the Korean Government in 2009 when it awarded him a Global Frontier Grant of approximately $140M over nine years. This grant forms the basis of The Medicinal Bioconvergence Research Center, or Biocon.  

Prof. Kim received his PhD at Brown University and was a post-doctoral fellow at MIT with Prof. Paul Schimmel.  He was the first employee at Cubist Pharmaceuticals before returning to Korea to begin his career in academia.  Prof. Kim received Korea’s prestigious Ho-Am Prize for Medicine in 2015. The award of $250,000 cited Prof. Kim’s work as a leading expert in the field of ARSs and related proteins.
