Yeon Sik Choi

Yeonsik Choi is a NIH K99 postdoctoral fellow in Rogers Research Group (Querrey Simpson Institute for Bioelectronics) at Northwestern University, working on creating bioresorbable polymer-based electrotherapeutic implants. Dr. Choi spent 2011-2015 as a senior researcher in the TECH R&D center at LG Chem. Ltd., developing polymer-based carbon nanotube nanocomposites. As a Cambridge Trust Scholar, he completed his PhD in the Department of Materials Science and Metallurgy at the University of Cambridge (2015-2018) on novel functional polymeric nanomaterials for energy harvesting applications.

Dr. Yeon Sik Choi specializes in the development of soft materials for electronic applications. As an experimentalist, his skills are in 1) designing soft materials based on fundamental insights, 2) synthesizing the materials using scalable methods, and 3) engineering high-performance electronic devices, including in-depth characterization to understand underlying mechanisms. His work has led to the creation of a range of novel soft materials and advanced electronic devices demonstrating strong performance metrics.

In 2021, Dr. Choi received the Pathway to Independence Award (K99/R00) from the National Institutes of Health (NIH). He is also the recipient of the IIN Outstanding Research Award (2021), the Baxter Young Investigator Award (2021), the Regeneron Prize for Creative Innovation (2021), the 2019 CSAR PhD Student Award, the ABTA Doctoral Researcher Award (2018), and two best paper, three best poster awards. Dr. Choi’s works have received extensive global media coverage. One of his inventions - bioresorbable cardiac pacemaker - is exhibited as a permanent collection at the Thackray Museum of Medicine in Leeds (UK). Dr. Choi is a Principal Investigator on several grants worth $1M in total.
