Education and Professional Experience

  • Ph.D., Mechanical Engineering, University of Illinois at Urbana-Champaign, 2013
  • M.S., Mechanical Engineering, University of Illinois at Urbana-Champaign, 2009
  • B.S., Mechanical and Aerospace Engineering, Cornell University, 2005
After completing his bachelor's degree, Dr. Watts continued his undergraduate research in x-ray diffraction of deforming polycrystals in the Miller research group, designing, constructing, and operating a combined mechanical fatigue test frame and goniometer. He then spent two years working in the area of reactor heavy equipment at the Knolls Atomic Power Laboratory in New York, concentrating on fatigue and fracture design rules for new and in-service equipment. He then began graduate studies at the University of Illinois under Daniel Tortorelli, working in the area of optimization of mechanical systems. His major projects included morphological modeling of composite microstructures for the Air Force Research Laboratory and using topology optimization to design thermoelastic metamaterials as part of a team lead by LLNL.

Research Interests

Optimization, particularly of mechanical systems, but including physical and non-physical systems generally; solution of such optimization problems in high-performance computing environments; numerical analysis and computational approaches to problems in mechanics, topology, geometry, and graph theory.
