Jong Eun Ryu

Assistant Professor

Dr. Jong Eun [Jon] Ryu joined NCSU in 2018. Dr. Ryu was an assistant professor at Indiana University-Purdue University Indianapolis (IUPUI) from 2013 to 2018. Dr. Ryu received his Ph.D. in Mechanical Engineering from the University of California, Los Angeles, in 2009 and received his BS and MS degrees from KAIST, Korea, in 2004 and 2006, respectively. Right after his graduate research, Dr. Ryu completed a two-year postdoctoral training in the plasmonic sensors at UCLA. Before he joined IUPUI, he worked for Intel Corp as a senior R&D engineer on advanced semiconductor lithography technology.

His primary research interest lies in harnessing the power of artificial intelligence to revolutionize the design and optimization of multiphysics and multiscale systems. By seamlessly integrating digital simulations and models, we aim to develop robust solutions that address real-world problems. One of the key aspects of our research is the implementation of digital twins for multiphysics systems, allowing us to create virtual counterparts that mirror the behavior of physical systems, enabling accurate predictions and informed decision-making.

The application areas of his research program are diverse and impactful. Ryu Group focuses on multifunctional composites, exploring their potential in areas such as photoacoustics, optics, anti-biofouling, superhydrophobic surfaces, electromagnetic interference (EMI) mitigation, flexible electronics, daytime radiative cooling for buildings, and photovoltaic (PV) panels. Additionally, our research extends to the 3D heterogeneous integration of electronics, aiming for high performance and reliability in electronic systems. We also research the development of next-generation smart materials tailored for ultrasound and piezoelectric applications, pushing the boundaries of what is currently possible in these fields. Lastly, our research extends to in-situ resource utilization, supporting the in-space manufacturing necessary for Lunar and Mars exploration.

Outside of work, Dr. Ryu enjoys spending time with his family, traveling, watching sports, and hiking.
