His main research focus is on the computational design and
control of materials processes including deformation and
solidification/crystal growth processes. Specific current projects
include the development of robust design simulators for deformation
and solidification processes, spectral stochastic methods for
modeling of uncertainty propagation in analysis, optimization and
design of continuum systems, and development of multi-length scale
algorithms for the analysis and design of microstructures in
engineering materials. He is also very active in interfacing robust
control of continuum systems with information technologies including
machine learning techniques in order to develop real time feedback
mechanisms for the control of complex materials processes in the
presence of uncertainty.
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.
