Biography (written in 2012 before Professor Ji joined UNIST):
Dr. Wooseok Ji is a postdoctoral research fellow in the Department of Aerospace Engineering at the University of Michigan Ann Arbor. He received his Ph.D. (2008) and MS (2005) in Aerospace Engineering, both from the University of Michigan, and BS (1999) in Mechanical and Aerospace Engineering from the Seoul National University. After his PhD, he joined the Center for Simulation of Advanced Rockets at the University of Illinois Urbana-Champaign as a postdoctoral research associate (2008-2009) and worked for IllinoisRocstar LLC as a research scientist (2009-2010). Prior to his PhD program, he worked as a tooling engineer for the Aerospace Division of Korean Air (1999-2003). His current research interests are in the fields of computational solid mechanics, multi-physics materials modeling from atomistic to continuum scales, fracture and failure mechanics of composite materials, advanced finite element method, and dynamic instability of composite structures.
Research Interests:
1. Textile composites for lightweight vehicles
2. Impact and ballistic response of composite structures
3. Characterization of nonlinear in-situ material properties
4. Computational tomography for reconstructing a multi-material microstructure
5. High-fidelity multi-physics and multi-scale models for composite materials and structures
6. Advanced manufacturing processes for modern composite structures
