Dr. Jungho Ryu is the principal researcher of Korea Institute of Materials Science (KIMS), Korea. He received the B.S. and M.S. degrees in materials science and engineering from Yeungnam University, Korea in 1996 and 1998, respectively. He awarded his Ph.D degree from school of materials science and engineering at Seoul National University, Korea in 2001 on Magnetoelectric composite materials. During his Ph.D work, he had been working at the International Center for Actuators and Transducers (ICAT) of the Pennsylvania State University on magnetoelectric composites and piezoelectric materials. After being awarded his Ph.D degree, Dr. Ryu became a post doctoral researcher at this center continuing his work on high power piezoelectric materials. Prior to joining KIMS in 2006, he was a senior engineer and project leader at the Samsung Electro-Mechanics Co. Ltd, Korea. His current research interests include the development and processing of the piezoelectric and ferroelectric devices, energy harvesting, ceramic processing, smart actuators, and functional thin/thick ceramics film fabrication through aerosol deposition method. He has authored over 200 publications in peer-reviewed international journals and >100 patents in the magnetoelectric, piezoelectric materials and devices, and functional ceramic films. Total number of citation on his research articles are over 4500 times and h index is over 30.
