Engineering Molecular Precision
We are a research group at UNIST dedicated to developing innovative synthetic methodologies for organic synthetic method designers and medicinal chemists.
Research Focus
01 — 03Radical Chemistry
Harnessing one-electron redox methods — photo- and electrochemistry — to expand accessible chemical space under sustainable conditions.
Organometallic Catalysis
Transition-metal catalysts, especially base metals, as a platform for unprecedented and selective transformations.
Mechanism Study
Elucidating how reactions operate through kinetic and computational analysis, then using that insight to design new transformations.
Recent
Publications
Our latest contributions to the global chemistry community, published in high-impact journals.
