Professor Zabaras' research group
performs applied and basic research in the interface of computational
mathematics and materials. His main research focus is on
multiscale modeling of materials (from ab initio to continuum)
and multiscale design of materials processes for control of
microstructure-sensitive properties. Emphasis of
recent work is in quantifying and controlling
uncertainty propagation in materials across scales.
For achieving these objectives, his laboratory is developing
a variety of mathematical and statistical computational tools
that include multiscale
and multiphysics materials simulators, homogenization
techniques, machine learning techniques for exploring
large multiscale material databases, level set and phase field
methods, techniques for modeling stochastic PDEs in high-dimensions,
Bayesian inference approaches and non-linear model reduction algorithms.
Professor N. Zabaras is the director of the Materials Process Design
and Control Laboratory and detailed information on current
research interests and list of publications and other activities can
be found at the MPDCL web site.
