Shih-Jung Liu is Professor of Mechanical Engineering at Chang Gung University (CGU), Taiwan. He completed his PhD on modeling and simulation of part warpage in injection molding at the University of Wisconsin-Madison, USA, in 1992. After one year's research at McMaster University of Canada, Dr. Liu joined the Polymer Rheology and Processing Laboratory at the CGU since 1993, and has been involved in pioneering work on the concepts of various polymer processing techniques.

Dr. Liu's research work deals with theoretical and experimental processing of various polymeric materials. He is worldwide known for the development of water-assisted injection molding systems and significant accomplishments in gas-assisted injection molding. He is also recognized for his works in precision molding, rotational molding, ultrasonic/hot plate welding, thermoforming and blow molding of various plastics, and the processing of biodegradable polymers.

Dr. Liu has delivered invited/keynote lectures at various international conferences and has been a frequent invited lecturer at various universities and industrial companies in Taiwan. He is the author of more than 200 scientific publications including 90 journal papers, editor and co-editor of 6 books and the author of 12 patents. He is also serving as the Editor for Asia and Australia for the Journal of Polymer Engineering (JPE) and serves in the Editorial Board for the Journals of Plastic, Rubber and Composites: Macromolecular Engineering (PRC-ME) and International Polymer Processing (IPP).
