Jonathan is the Assistant Dean (Student Affairs) of the Faculty of Engineering and an Associate Professor in
the Department of Biomedical Engineering (BME) and the School of Life Sciences (by courtesy) at The Chinese
University of Hong Kong (CUHK). In August 2013, he joined CUHK as an assistant professor in the BME
Program, then administered by the Department of Electronic Engineering. In July 2017, he joined the newly
inaugurated CUHK Department of BME as a founding faculty member. He became an associate professor with
tenure in August 2019.
Jonathan is the Communications Chair of the Bioinspired and Biomimetics Delivery Focus Group within the Controlled Release Society (CRS) and a senior member of the American Institute of Chemical Engineers (AIChE). He has recently served as a guest editor for the special issue entitled “Nanomedicines beyond Cancer” for Molecular Pharmaceutics.
Professional Education and Training
2013 Croucher Foundation Postdoctoral Scholar, Northwestern University
2011 Ph.D. in Chemical Engineering, California Institute of Technology
2006 M.S. in Chemical Engineering, Stanford University
2005 B.S. in Chemical Engineering, Stanford University
The Choi group aims at developing novel techniques for delivering non-cationic bionanomaterials (e.g., DNA-coated nanoparticles, alkyl-terminated nanoparticles, and polydopamine-coated nanoparticles) to various target cell types in vitro and diseased locations in vivo for therapeutic applications. A rational approach to facilitating targeted delivery of bionanomaterials is to develop a comprehensive understanding in their fundamental interactions with the biological system (or bio-nano interactions). For in vitro studies, we elucidate the mechanisms for the endocytosis, intracellular trafficking, and exocytosis of NPs. For in vivo animal studies, we study the distribution of NPs down to the tissue, cellular, and subcellular levels.
