Uncertainty quantification uses statistical principles to quantify the probability of a designed part successfully functioning during its anticipated life span, and/or the accuracy of test results. Data-driven modeling tries to learn from available data instead of traditional modeling with hard-coded instructions.

My research focus is computational fluid dynamics and heat transfer in turbulent multiphase, multicomponent systems. I develop methods and apply them to engineered and natural systems. These methods can be applied to material processing which involve a liquid state or solids mixed in liquids.

My research lies in the interdisciplinary field of computational inverse problems, where the main goal is to estimate underlying model parameters or internal structures from observed measurements (biology, engineering, imaging). The main challenges toward obtaining meaningful real-time solutions are ill-posedness, large parameter dimensions, complex model constraints, and providing uncertainty estimates.

We work on multi-scale computational methodologies to achieve a comprehensive understanding of processing, microstructure, and material properties. The main research topics are Integrated Computational Materials Engineering (ICME), multi-scale modeling, optimization, uncertainty quantification, reduced order modeling, and machine learning to study material behavior at length scales ranging from microstructure to component.
