I am a third year student pursuing Doctoral degree under supervision of prof., Hakjune Rhee at department of Bionanotechnology, Hanyang University in South Korea. I am majoring in Organic Chemistry and Organic Synthesis. I am interesting in the preparation of immobilized catalysts and the application for cross coupling reactions. In addition, I am studying synthesis of carbohydrate at the same time. As a result, I published one paper about total synthesis of L-ribose from D-ribose in this year.
