Young-wook Jun, Ph.D.
Associate Professor

Young-wook Jun attended Yonsei University in Korea, where he received a Bachelor's degree in Chemistry in 1999. He did his graduate studies at the Korea Advances Institute of Science, where he worked under the supervision of Professors Sang Youl Kim and Jinwoo Cheon. His Ph.D. thesis concerned the chemistry of nanocrystals. He carried out postdoctoral studies with Prof. Paul Alivisatos at the University of California, Berkeley, in 2007 and it was at this time that he first began research related to single molecule imaging using nanocrystal probes. In 2010, he joined the faculty of UCSF, where he is presently Associate Professor. He received the Endowed Hemming Fellowship, Sandler-UCSF New Frontier Research Award, and IUPAC Young Chemist-Honorable Mention Award. His research focuses on nanoprobing systems to investigate spatiotemporal dynamics of cell signaling involved in cellular developments such as gene regulation, cell-to-cell communications, and neuron circuit formation.
