Philippe Talatchian

Philippe Talatchian is a UMD Postdoctoral Researcher in the Alternative Computing Group in the Nanoscale Device Characterization Division of the Physical Measurement Laboratory (PML). He received his M.S. at The Paris-Diderot University in Quantum device systems and his Ph.D. at The Paris-Sud University (Orsay) in Condensed Matter Physics. His doctoral thesis focused on the synchronization of spin-torque nano-oscillators for brain-inspired computing. He demonstrated for the first-time neuromorphic computing and learning with four coupled nanoscale oscillators. Philippe is working with Mark Stiles on experimental implementations of networks of superparamagnetic tunnel junctions for building and demonstrating energy-efficient computing approaches.
