Degrees

  • Mechanical Engineer, University of Buenos Aires, '02

  • Ph.D., Aeronautics (Minor in Materials Science), California Institute of Technology, '11

Research Interests

  • Predictive, multi-scale modeling and simulation of microstructure evolution in confined granular systems, with an emphasis in manufacturing processes and the relationship between product fabrication and performance.
  • Application areas of interest 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) materials.
