About the Speaker

Gun Kim is an Assistant Professor in the Department of Civil, Urban, Earth, and Environmental Engineering at Ulsan National Institute of Science and Technology (UNIST), South Korea. Before joining UNIST in 2020, he worked as a Postdoctoral Research Associate at the Carle Illinois College of Medicine, University of Illinois at Urbana-Champaign.

He received his Ph.D. degree (2016) in Civil and Environmental Engineering, and his M.S. degree (2016) in Mechanical Engineering at Georgia Institute of Technology. Before moving to the U.S., he received his M.S. degree (2011) in Applied Mechanics and B.S. degree (2009) in Civil and Environmental Engineering at Yonsei University, Seoul. His research interests include developing non-traditional, bio-inspired, entangled polymeric materials capable of visualizing stress and activating targeted chemicals.

The focus of his work is the innovation of sensors and polymers, driven by the spatiotemporally released ultrasound energy.

Abstract

Developing a novel modality that synergistically enhances the functionalities and mechanical properties of existing engineering materials is crucial in addressing the grand challenges associated with sustainability and resilience. Ultrasound, capable of bridging multiple disciplines, including mechanics, polymer chemistry, material engineering, and medicine, plays an important role in this endeavor.

This talk discusses our recent progress in ultrasound research within civil engineering, covering three key areas:

  1. early-stage damage detection in cementitious materials, integrated with quantitative ultrasound imaging techniques;
  2. the design of multifunctional polymers capable of self-visualizing external forces, enabling real-time structural health monitoring; and
  3. the development of new ultrasound-based platforms for remotely generating reactive oxygen species (ROS), leveraging the advantages of technologies for cancer therapy (mechanodynamic therapy) and contaminant treatment (PFAS elimination).

Taken together, these topics collectively pave the way for discussions on novel approaches to creating advanced, adaptive systems tailored for enhancing human society.
