William Borders (Fed)

Electrical Engineer

William Borders is an Electrical Engineer in the Alternative Computing Group in the Nanoscale Device Characterization Division of the Physical Measurement Laboratory (PML). He received a B.S. in electrical and computer engineering from North Carolina State University and an M.S. and Ph.D. in electronic engineering from Tohoku University in Japan. For his doctoral research, he studied stochastic magnetic tunnel junctions and their use as a key component in probabilistic computing-based applications. His current work focuses on demonstrating intermediate scale neural network hardware implementing novel devices for next-gen AI applications.
