Education and early career Rhyee obtained his Bachelor's in Physics from Chung-buk National University in 1998, and a Master's in Experimental Solid-State Physics from Pohang University of Science and Technology (POSTECH) in 2000 under advisor Sung Ik Lee. He pursued a Ph.D. in Magnetic Materials at Gwangju Institute of Science and Technology (GIST) from 2000 to 2005, researching Hexaboride compounds under advisor Beong Ki Cho.

Career Rhyee worked as a Postdoc Researcher in the Crystal Growth group at Max Planck Institute for Solid State Research in Germany from April 2006 to April 2007 and then served as an R&D Staff Researcher at the Materials Research Lab at Samsung Advanced Institute of Technology (SAIT) from May 2007 to August 2010. He moved into academia as an assistant professor at the Department of Applied Physics of the Applied Science College at Kyung Hee University in South Korea in 2010, becoming associate professor in 2014 and Professor in 2019

While in the role of associate professor, Rhyee concurrently held the position of department chair for the Department of Applied Physics from March 2017 to February 2019, and as the Vice Dean of the Applied Science College at Kyung Hee University from March 2018 to February 2019. He has been serving as the Outside Director at KPT since June 2022, as well as the CTO at R-Materials in South Korea since January 2023, and has also been acting as the Representative CEO of V-memory in South Korea since January 2020.

Magnetism and thermoelectric research

Within his magnetism and thermoelectric research, Rhyee has explored unconventional magnetism in boride and intermetallic compounds, with a focus on magnetic polaronic transport and correlated properties. He examined the link between topological states and thermoelectricity, discovering that the topological phase transition in Dirac semimetals boosts thermoelectric performance. Further investigations revealed that selective charge Anderson localization is a novel avenue for enhancing thermoelectricity, yielding a ZT value of 2.0 in n-type thermoelectric power generation. In a collaborative work, he presented a novel magnetic field-induced type II Weyl semimetallic state in the Shastry-Sutherland lattice, characterized by non-trivial Berry phase, magnetic field-induced Weyl nodes and spin chirality, chiral anomaly, anomalous magnetoconductivity, and demonstrated topological phase evolution.
