Dr. Ilhan Chang serves as an adjunct Senior Lecturer in the School of Engineering and Technology at UNSW Canberra, University of New South Wales, and as an Associate Professor in the Department of Civil Systems Engineering at Ajou University, South Korea. He obtained his Bachelor of Science in 2000, Master of Engineering in 2004, and Doctor of Philosophy in 2010, all in Civil and Geotechnical Engineering from the Korea Advanced Institute of Science and Technology (KAIST). His Master's dissertation addressed 'Soft Soil Evaluation using Elastic Waves,' while his PhD focused on 'Soil Stabilization using Microbial Biopolymers.' Chang began his academic career as a Research Assistant Professor at KAIST from 2010 to 2011, followed by a role as Senior Researcher at the Korea Institute of Civil Engineering and Building Technology from 2012 to 2017. During this period, he also served as Invited Professor at KAIST from 2014 to 2015 and Adjunct Associate Professor at the University of Science and Technology from 2016 to 2017. Joining UNSW in April 2017 as a Lecturer, he advanced to Senior Lecturer in July 2018, holding the position until August 2020, and has continued as Adjunct Senior Lecturer since September 2020.

Chang's research expertise encompasses geotechnical engineering, multi-disciplinary bio-soil studies, sustainable and environmental geotechnology, ground improvement, site characterization, and industrial cooperation. His work emphasizes biopolymer applications in geotechnical engineering, new material development, soil characterization and improvement, micro-mechanics, hydraulic geotechnology, soil erosion, desertification, and space and planetary geotechnical engineering. He leads the E3GEO research group, dedicated to emerging, environmental, and extreme geotechnical engineering. Notable publications include 'Review on biopolymer-based soil treatment (BPST) technology in geotechnical engineering practices' (2020), 'Geotechnical engineering behaviors of gellan gum biopolymer treated sand' (2016, Canadian Geotechnical Journal), 'Water-retention properties of xanthan-gum-biopolymer-treated soils' (2023, Environmental Geotechnics), 'Cr3+-crosslinked xanthan gum hydrogels for enhancing penetration efficiency and post-installation pullout resistance of bioinspired piles' (2025, Geomechanics and Engineering), and 'Effects of xanthan gum treatment on sedimentation and consolidation of kaolinite aggregates' (2025, Journal of Rock Mechanics and Geotechnical Engineering). His contributions support practical implementations and collaborations through affiliations with international university alliances.
