Education

• Integrated Master of Science/Doctor of Philosophy (MA/PhD), Mechanical Engineering, Seoul National University (2021)
• Bachelor of Science (BS), Automotive Engineering, University of Bath, UK (2014)

Research Focus

• Composite Manufacturing

  • Liquid Composite Molding (LCM), with a particular emphasis on optimizing the Out of Autoclave (OOA) process.
  • Quasi-isotropic discontinuous fiber-reinforced composite structures.
  • Sustainable and environmentally friendly hybrid composite structures, incorporating both natural and synthetic fibers.
  • Extrusion-based composite additive manufacturing, with a focus on the integration of long discontinuous fiber structures.

• Metal Additive Manufacturing

  • Hybrid post-processing techniques, such as cavitation peening and electrochemical polishing, to enhance both surface microhardness and surface roughness in metal additive manufacturing.

Awards and Honors

• BK21plus fellowship, Seoul National University, Korea
• Academic Scholarship, Seoul National University, Korea
• NSF Early Career Research Travel Award
