Research Summary

From light-based computing and communication to the environmentally-friendly and cost-effective conversion of light from the sun into fuels and/or electrical energy, understanding and controlling the interaction of light and matter remains one of the great scientific challenges of the 21st century. With an emphasis on the study of light-matter interactions in crystalline materials, research in the Benedict lab involves the synthesis of novel materials and the development of new characterization techniques important to many areas of chemistry and physics:

  • Developing novel stimuli-responsive crystalline nanoporous materials.
  • Fabricating new devices for in situ X-ray diffraction experiments including guest exchange and photocrystallography.
  • Designing and constructing versatile microscopes for time-resolved spectroscopy and imaging and improved pumping in TR-XRD experiments.
  • Exploring the effect of the local chemical environment on the nucleation and growth of photoproducts in solid-state chemical reactions and phase transitions.
