Prof. HAN-ILL YOO

Professor Emeritus, Seoul National University, Korea

Invited Chair Professor, Daegu Gyeongbuk Institute of Science & Technology, Korea

President (2017-2019), International Society for Solid State Ionics

Prof. Han-Ill Yoo went to Seoul National University for BS and Korea Advanced Institute of Science and Technology for MS both in materials, and got Ph.D in Ceramics from the Department of Materials Science and Engineering, Massachusetts Institute of Technology, USA. in 1984. He had since affiliated with the faculty of the Department of Materials Science and Engineering, Seoul National University.

His research interest has been mainly with the defect chemistry and transport properties of mixed ionic electronic conductors. Among others, he discovered a material with 0 thermopower, implemented the experimental methods to determine all the ionic and electronic transport properties in terms of the Onsager transport coefficients, and experimentally confirmed the Onsager reciprocity between ionic and electronic flows. Recently, he has been inquiring into the nonisothermal ionic/electronic transport properties of mixed conductors.

He was awarded the Humboldt Research Award in 2004 and elected to Fellow at College of Engineering, The University of Tokyo in 2009.

His lifelong passion was trekking into high mountains including Mt. Kilimanjaro (5895m high) in Tanzania; Kala Pattar (5,545 m), Annapurna Base Camp (4130 m), Gosainkund (4380 m), Kyangjin Ri (4550 m), Langtang Himal in Nepal;  Mt. Rinjani (3726 m) in Indonesia; Mt. Whitney (4421 m) in USA, etc.
