Grace Rohaley, Ph.D.

I am a Post-Doctoral Associate working part-time in the Mechanical Engineering Department with the Microsystems and Mechanobiology Lab as well as part-time with the Materials Characterization Facility at Carnegie Mellon University as a SAXS expert.

Current Projects

  • Development of rapid manufacturing protocols for mass-production of DNA origami configurations.
  • Instrument maintenance, operating procedure development, teaching/training with Xenocs Xeuss 3.0 SAXS/WAXS X-ray Diffractometer.

Previous Experience

In my graduate research, my studies surrounded the study of organic liquid crystal systems with distinct and interdisciplinary focuses including zero-power toxic gas sensing and liquid crystal elastomer research for tissue engineering.
