Professor Chang-Sik Ha is a polymer scientist, a material scientist, and a writer. He is a polymer and/or materials scientist at Pusan National University, Korea and a writer. His research interests as a polymer and materials scientist include periodic mesoporous organosilicas (PMOs), organic– inorganic nanohybrid materials and functional polymers (especially, polyimides and silsesquioxanes) for various applications. He is a Distinguished Professor at the School of Chemical Engineering, Pusan National University (PNU), Korea since 2021.

He joined at the Department of Polymer Science and Engineering, Pusan National University as a Full-time Instructor in 1982. After promoting to Assistant Professor and Associate Professor at the same university in 1985 and 1989, respectively, he became a Professor at the same university in 1994 till 2021. After he was officially retired in 2021 and he has been appointed as a Distinguished Professor at the same university and continued his research, while holding the title of Emeritus Professor together at the same university. He also served as a vice president of the Pusan National University in 2012~2013. During his professor career, he worked at four universities in USA each for one year as a visiting scholar; worked with Prof. Ryong-Joon Roe at the University of Cincinnati in 1988~1989, with Prof. Curtis W. Frank at the Stanford University in 1997~1998, with Prof. Joseph A. Gardella, Jr. at the State University of New York at Buffalo in 2004, and with Prof. Jeffrey I. Zink at the University of California at Los Angeles in 2010~2011, respectively. He also worked with Prof. Yoshiharu Doi of RIKEN, Japan (1999) and Prof. Takashi Inoue of Tokyo Institute of Technology, Japan(2000) during his short-time (ca. one month) stay.

As a polymer and materials scientist, he served as an Editor-in-Chief of the Macromolecular Research from 2008 till 2010. He has been served as an Editor for Asia of the Composite Interfaces since 2008 as well as an editorial board member of several international journals including Materials and Macromol., etc. till now. He served as the president of the Society of Adhesion and Interface, Korea in 2012-2013.

Prof. Ha has been selected as a fellow of the National Academy of Engineering of Korea as well as the Korean Academy of Science and Technology since 2004. He also served as a Director of the National Research Laboratory of Nano-Information Materials from 2003~2008 and Pioneer Research Center for Nanogrid Materials, respectively, which were supported both by the National Research Foundation of Korea from 2010 till 2016. He also worked with Prof. Dongyuan Zhao at Fudan University, China from 2008~2011 under the program of the Korea-China Joint Research Center program. He was designated as an Honorary Professor at the University of Queensland, Australia from 2013 till 2015. He published over 200 papers in domestic journals and 600 international journals, and filed ca. 70 patents.

He also organized several international symposia including the Asian Symposium on Advanced Materials(ASAM), which has been continued till now every two year after the 1st ASAM was organized at Vladivostok, Russia with Prof. Yury Shchipunov of Russian Academy of Sciences in 2007. After the ASAM at Vladivostok, the ASAM was held at Shanghai, China (2009), Fukuoka, Japan (2011), Taipei, Taiwan (2013), Busan, Korea(2015), Hanoi, Vietnam (2017), Beijing, China (2019), Novosibirsk, Russia(2023) and Busan, Korea (2025). He also served for the Subcommittee on the Structure and Properties of Commercial Polymers East Asia Research Meeting in the International Union of Pure and Applied Chemistry (IUPAC) as a chairperson in 2014~2017.

Through his research career, he has focused on the enhancement of interfacial interaction and applications of polymer blends and polymer based nanohybrid materials. In his early research, Ha worked on the miscibility and compatibilization of polymer blends and polymer nanocomposites as well as their structure-property relationship, while his research interests were expanded to the organic-inorganic nanohybrids, silsesquioxane based materials, and superhydrophobic coating materials. He has devoted to the development of colorless polyimides and/or low-dielectric constant polyimides and their hybrid materials for flexible displays. He has been also worked on the development of periodic mesoporous organosilicas (PMOs) and their applications for drug delivery, environmental adsorption and flexible displays and so on.

He wrote 20 scientific books. Apart from his activity as a polymer and materials scientist, he has worked also as an author and published 17 essay books in Korean. Three of his essay books titled “25 World Literatures that Touched My Mind”, and “An Engineering Professor Falls for Beethoven” and “An Engineering Professor Talks Convergence of Arts,” were selected as one of the Sejong Books in the field of liberal arts category in 2022 and 2025, respectively, by the Publication Industry Promotion Agency of Korea. Selected Sejong Books are purchased by the agency and distributed free of charge to libraries nationwide. After his official retirement from Pusan National University in 2021, Ha has been known as an engineering professor specializing in the Convergence of Arts by continuing public lectures and writing books on the subject. Moreover, he has had lectures for two semesters every year with the title as the “Hyowon Essay Academy” at the Future Citizen’s Education Center of Pusan National University since 2021.

Ha served as the president of the Busan Catholic Writers Association (2015~2016) and the Society of Busan Essay Writers(2021~2014). Ha also served for the Catholic Diocese of Busan as the President of the Council of the Laity Apostolate for the Catholic Diocese of Busan for four years from 2012 to 2016. He met Pope Francis when he visited Korea in 2014 for the beatification of the 124 Martyrs in Korea as one of 153 lay representatives.
