Biographical Statement

Li-Wei Chang received his BS degree in Chemical Engineering from National Chung Hsing University and then he obtained his MS degree from National Central University. He studied the thermodynamics of interaction between a novel antimicrobial peptide “indolicidin” and cell membrane during his masters degree period. He begun working as a process engineer in the CIGS thin film solar cell department of Taiwan Semiconductor Manufacturing Company (TSMC). During his time at TSMC, he worked on developing new process and how to improve the efficiency of solar cell and yield of manufacturing. Now Li-Wei is working on understanding the role of charge and chemical patterning on complex coacervation. By systematically analyzing how charge and chemical patterning affects the property of coacervates, his goal is to design coacervate-based materials to stabilize vaccines over a wide range of temperatures. In the future, he wants to combine what he learned from academic and industrial fields and do some contribution in academy or industry. During his free time, Li-Wei likes playing tennis, ping-pong, bowling, going to karaoke, traveling and exploring good food. He can always be found in Oriental Flavor, Ginger Garden, Amherst Chinese restaurant and Rao’s Coffee.

Li-Wei participated in an internship in spring 2018 with BASF in Ludwigshafen, Germany.

Dr. Li-Wei Chang successfully defended his PhD dissertation on Sequence Control in Complex Coacervates on February 13th, 2020. Dr. Chang was the first PhD student to graduate from the Perry Lab! He has since moved on to a postdoctoral position in the lab of Prof. Daeyeon Lee at the University of Pennsylvania.
