Pedram Khalili-Amiri (Linkedin, Lab) is an assistant adjunct professor in the department of electrical engineering at UCLA. He has served as a research associate and program manager at UCLA since 2009, where he led two DARPA multi-institution programs, focusing on the development of spin-transfer-torque magnetic random access memory (STT-RAM) and non-volatile magnonic logic (NVL), working with several university and industry partners.  These programs resulted in some of the world’s fastest and lowest-power magnetic memory technologies to date. Dr. Khalili is also currently leading the memory development efforts within the NSF TANMS center, focusing on ultralow-power electric-field-controlled magnetic memories. In addition, he is co-founder and chief technology officer of Inston Inc., a UCLA spin-off company. He is also affiliated with the center for Function Accelerated nanoMaterial Engineering (FAME), and the Western Institute of Nanoelectronics (WIN).

He received the B.Sc. degree from Sharif University of Technology in 2004, and the Ph.D. degree (cum laude) from Delft University of Technology (TU Delft), The Netherlands, in 2008, both in electrical engineering.  He was a best student paper award finalist at the IEEE International Magnetics Conference (Intermag) in 2008.  His professional activities have included serving as a guest editor for Spin, and serving on the technical program committee of the Joint MMM/Intermag Conference. 

Prof. Khalili’s research interests include nano-magnetism and spintronics, in particular nonvolatile magnetic memory and logic, magnetic tunnel junctions, electric field control of magnetism, spin-transfer torque, spin-orbit torques, spin waves, and microwave magnetic devices.
