Prof. Choi received his BS (with Summa Cum Laude), MS, and Ph.D. degrees all from the Department of Chemistry, KAIST, in 1991, 1994, and 1998, respectively. Before joining KAIST, he had been with the Basic Research Laboratory at Electronics and Telecommunications Research Institute (ETRI), Korea, as a senior/principal researcher. He invented the flexible memristor based on graphene oxide films in 2009, which opened the nonvolatile memory and neuromorphic applications of the graphene-related materials. He also demonstrated a large-area organic light-emitting diode with the graphene anode electrode for the first time in 2010.
Prof. Choi joined the faculty of the School of Electrical Engineering, KAIST in November 2011. His primary research objectives have been to understand the underlying principle in the conduction/switching behavior of a single molecule or molecular-scale materials and to develop functional devices utilizing these materials. His academic contributions are mainly in the applications of graphene and 2D materials to novel electronic and display devices.
He has authored more than 150 refereed papers and contributed more than 200 presentations at conferences. He holds 34 Korean and 14 US patents, 3 of which were licensed to global companies. He received several academic awards including the Prime Minister's Award for Research Innovation in Nanotechnology at Nano Korea 2015, the KIDS Award Silver in IMID 2016, and the Prize for Academic Excellence of KAIST in 2017.

Abstract
Two-dimensional (2D) materials, represented by graphene and transition metal dichalcogenides (TMDCs), have attracted tremendous research activities worldwide as innovative materials for the application to next-generation displays due to their unique properties such as versatile electrical conductivity, optical transparency, and mechanical flexibility/stretchability. During the past years, my research group has demonstrated the integration of graphene and TMDCs to the front panel and back-plane of display devices [1-5]. In this talk, I will present recent advances in the application of graphene electrodes and TMDS channels to flexible or stretchable displays
