Matthew Daniels (Fed)

Matthew Daniels is a staff physicist in the Alternative Computing Group in the Nanoscale Device Characterization Division of the Physical Measurement Laboratory (PML). He received a B.S. in physics from Clemson University and a Ph.D. in physics from Carnegie Mellon University. For his doctoral research, he developed a semiclassical formalism for exposing a novel, spin-like degree of freedom in antiferromagnetic spin waves. Matthew is working on theoretical models for neuromorphic computing with spintronic devices and on using physics to understand, develop, and quantify energy-efficient computing schemes, information encodings, and coprocessors.
