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 interest is advancing back-end-of-line emerging device technologies, such as resistive memory (ReRAM), oxide-channel transistors (OxFET and ECRAM), ferroelectric memory, phase-change memory (PCM), and volatile memristors. His research spans crossbar array architectures for hardware applications, including analog in-memory computing-based AI accelerators, oscillatory neural networks, and cryptographic security hardware such as 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 photonic devices and optical interconnects for co-packaged optics.
