INTRODUCTION

Dr. Isaiah J. Lim, originally from South Korea, developed a deep interest in physics at a young age, inspired by the TV show "MacGyver." This early fascination led him to pursue higher education in the field, earning a B.S. in Physics and a M.S. in Theoretical Solid-State Physics at Dankook University, South Korea. He continued his academic journey in the United States, obtaining another M.S. in Physics at Western Illinois University, followed by a Ph.D. in Experimental Condensed Matter Physics at Washington University in St. Louis under the guidance of Dr. James S. Schilling. During his doctoral research, Dr. Lim explored magnetism and superconductivity under high-pressure conditions.

As a postdoctoral research associate in Dr. Choong-Shik Yoo’s group at Washington State University, Dr. Lim expanded his expertise by researching dense low-Z materials. His work involved advanced techniques such as in-house confocal Raman microscopy and synchrotron X-ray measurements at the Advanced Photon Source at Argonne National Laboratory. Dr. Lim later held a second postdoctoral researcher position in Dr. James J. Hamlin’s laboratory within the Department of Physics at the University of Florida, where his research focused on pressure-induced/enhanced metastable superconductivity in low-Z-rich materials.

Dr. Lim joined the Department of Physics at 海角社区 as an assistant professor in Fall 2024.
