Kim CheolGi

Kim CheolGi (Korean 김철기: born February 27, 1961) is a South Korean Scientist and Professor at DGIST as well as the director of Magnetics initiative life care research center. He won Distinction medal from Montpellier University (2014), and AUMS award (Asian Union of Magnetics Societies, 2020).
==Careers==
Kim attended Simin high school in Daegu, South Korea, and received B.S. degree in 1983 in Physics Education at Seoul National University. He received M.S in 1986 and Ph.D degree in 1989 in the field of solid state Physics from KAIST. Kim began his research at Korea Research Institute of Standards and Science in Korea and the National Institute of Standards and Science in USA. Kim had started his Professorship carrier from 1996 for research and teaching and appointed at several domestic and worldwide Universities, Sun Moon U, Chungnam National U, McMaster U, Tohoku U, Bielefeld U. In 2014 he moved to DGIST and served as Director of CCRF, Department chair Professor of Emerging Materials Science, and Dean of graduate school, and also President of DGIST Professor council.  He became founding director of three biomedical convergence research centers, Center for NanoBio-Engineering & Spintronics (WCU) in 2009, Center for Bio-Convergence Spin System in 2017 and Magnetic Initiative Life Care Center in 2018. He also served as Co-Director of Key lab for Nano-Micro-technologies, Vietnam national University from 2017.
==Scientific contributions==
Kim has done numerous revolutionary and original works on Bio-Convergence magnetism; First demonstration of digital magnetophoretic circuitry platform, opening the innovative ‘Spintronics based Celltronics’, and development of magnetoresistive based ultra-sensitive on-chip magnetometer with the ultra-low magnetic moment resolution.
He has done real pioneering works for multiplexed living cell tweezers in magnetophoretic platform. He has developed a concept for the digital manipulation and trapping using nano-/micro-devices of magnetic multilayers, which enables the circuitry manipulation of living cells as well as autonomous separation and trapping depending on the individual cellular characteristics. He is installing these unique devices to investigate the electromagnetic, mechanophysical and biochemical properties in single cell level, which is much more improved performance over optical tweezers.
Another specific development from his contribution is the novel PHMR magnetometer (Planar Hall magnetoresistance (HPMR), commonly called as PHR). He introduced the exchange bias structure for coherent magnetization rotation in PHMR for improving field sensitivity with much higher thermal stability compared with the Spintronics based GMR and TMR sensors. Especially PHMR magnetometer has demonstrated ultra-sensitive detection capability of magnetic moment in robust environment,  including magnetic biochip.
==Honors and awards==
