Problems

Our research sits at the interface of virtual-physical particulate engineering, and it focuses on developing predictive modeling, simulation, and characterization techniques, at and across different scales, to further the understanding of microstructure formation and evolution in confined particulate systems, with an emphasis in manufacturing processes and the relationship between product fabrication and performance.


Approach

We use an interdisciplinary approach that combines predictive modeling, simulation, and characterization techniques, at and across different scales.

Findings

We aim to further the understanding of microstructure formation and evolution in confined particulate systems, with an emphasis in manufacturing processes and the relationship between product fabrication and performance.

Impact

Our key areas of research impact include: (i) particulate products and processes (e.g., flow, mixing, segregation, consolidation, and compaction of powders), (ii) continuous manufacturing (e.g., Quality by Design, model predictive control, and reduced order models), and (iii) performance of pharmaceutical solid products (e.g., tensile strength, stiffness, swelling and disintegration), biomaterials (e.g., transport and feeding of corn stover) and energetic materials (e.g., deformation and heat generation under quasi-static, near-resonant and impact conditions, and formation and growth of hot spots).
