Wooseok Choi

Dr. Wooseok Choi earned a B.S. in Electrical Engineering from Korea University, Seoul, and a Ph.D. in Materials Science and Engineering from Pohang University of Science and Technology (POSTECH), South Korea. Since 2023, he has been a Postdoctoral Researcher at IBM Research Europe – Zurich, Switzerland.

His research focuses on advancing back-end-of-line emerging device technologies, including resistive memory (ReRAM), oxide-channel transistors (OxFET and ECRAM), ferroelectric memory, phase-change memory (PCM), and volatile memristors. His research also spans crossbar array architectures for unconventional computing hardware systems, such as in-memory computing based analog deep learning accelerators, oscillatory neural networks (ONN), and cryptographic security hardware (TRNG and PUF). The work includes innovations in materials, device design, characterization, and software development. Beyond the electrical domain, his research has expanded into the optical domain, focusing on silicon photonics and optical interconnects for co-packaged optical I/O chiplets

Dr. Choi is the inventor of 12 patents (US & KR) and has authored over 40 scientific publications (10 as 1st author) in leading journals and conferences, including Advanced Science, Advanced Functional Materials, IEEE EDL, TED, ESSERC, IMW, VLSI Symposium, and IEDM.
