Research centers on mathematical analysis
and computational methodologies
for stochastic and multiscale, multi-physics modeling in science and engineering.

Mathematical theory of solids at the atomic
and macroscopic scales
The main objective is to develop a rigorous mathematical theory
for solids. This requires understanding models of solids at the
electronic, atomistic and continuum level, as well as the relation
between these models. Problems of interest include: (1). The
crystallization problem: Why solids take the form of crystal lattice at
zero temperature? (2). The Cauchy-Born rule, which serves as a
connection between atomistic and continuum models of solids.

A posterior error estimates
Work done in Master degree thesis, under the guidance of
Professor Hongci Huang at the Chinese Academy of Sciences. The main
focus is on finite element for problems with corner singularities.
Issues discussed include: A posterior error estimates, direct and
inverseerror estimates on locally refined domains, convergence of
multi-grid methods on such domains, etc.
