Dr. Angela R. Hight Walker is a distinguished scientist at NIST known for her pioneering work in optical spectroscopies, particularly Raman and photoluminescence, to study quantum materials. Over her 30-year career, she has led research on low-dimensional materials and contributed to nearly 200 publications at the intersection of physics, chemistry, and materials science.
Hight Walker is a Fellow of the American Physical Society, American Association for the Advancement of Science, and Sigma Xi. She plays a key role in international nanotechnology and Raman standardization efforts. A passionate advocate for science education, she actively engages students and researchers through demonstrations, lectures, and conferences.
Hight Walker has developed novel instrumentation for quantum material characterization, including combined magneto-optical magneto-transport Raman spectroscopy, imaging, and mapping. These techniques provide powerful non-contact, non-destructive optical probes of quasiparticles and fundamental physics in graphene and other 2D materials. Raman spectroscopy is particularly useful for studying electronic structure and interactions in quantum materials, while magneto-Raman spectroscopy enables spatially-resolved measurements with diffraction-limited optical resolution and simultaneous electrical magneto-transport measurements.
