Instrumentation Experience

Operating the Rigaku SmartLab X-ray Diffractometer (XRD) at the University of California, Irvine (UCI) Materials Research Institute (IMRI).

With each instrument I build and/or learn to operate, I gain a new way to explore materials and their properties. I’m inspired by what I see under a microscope or within a spectra. I find joy in developing and performing innovative experiments.

Below is a list of the many instruments and techniques I have dedicated days, months, and years to learning. Through these I deepened my understanding of physics, chemistry, and materials science, and made discoveries for scientific and engineering teams in academia, government, and industry labs that have been published or patented.
