Research Interests
  • My research is in Applied Analysis, including but not limited to:
  • Analysis of Partial Differential Equations
  • Calculus of Variations
  • Continuum Mechanics (Elasticity)
  • Composite Materials, Metamaterials

  • Short Bio

    I did my Ph.D. (degree received in 2012) at Hausdorff Center for Mathematics under the supervision of Prof. Stefan Mueller. Before joining the UCSB, I held postdoctoral positions at Temple University (with Prof. Yury Grabovsky), University of Utah (with Prof. Graeme Milton) and EPFL (with Prof. Hoai-Minh Nguyen). Here is my CV
