Chang-Sik Ha is a professor at the Department of Polymer Science and Engineering, Pusan National University (PNU), Korea since 1982. He received his PhD in Chemical Engineering from Korea Advanced Institute of Science and Technology(KAIST), Seoul, Korea in 1987. He served as a Vice President of PNU, Director of the Pioneer Research Center for Nanogrid Materials, the Honorary Professor of University of Queensland, Australia, and Associate Editor of both the Advanced Porous Materials and the Composite Interfaces. He was appointed as the University Distinguished Professor in 2016. He has been elected as the members of both the Korea Academy of Science and Technology and the National Engineering Academy of Korea in 2004. He published over 750 papers in peer-reviewed journals, 70 patents, and 24 book or book chapters. He received several honorable awards including Samsung Polymer Science Award from the Polymer Society of Korea(2011) and the SPSJ International Award from the Society of Polymer Science, Japan(2017). His research interests include periodic mesoporous organosilicas (PMOs), organic–inorganic nanohybrid materials and functional polymers for various applications.Sung Soo Park is a research professor in Pusan National University (PNU), Korea since 2003. He received his PhD (in 2002) in Chemistry from Inje University, Korea. Before he joined PNU, he was a postdoctoral research fellow in Korea Advanced Institute of Science and Technology, Korea in 2002. He published over 80 papers in peer-reviewed journals and 25 patents. His main research interests include periodic mesoporous organosilica materials and organic–inorganic hybrid nanocomposites for application in the area of drug delivery, photosensing, and adsorption of gas and metal ions.
