Tiffany S. Santos (Member, IEEE) received the S.B. and Ph.D. degrees in materials science and engineering from the Massachusetts Institute of Technology (MIT), Cambridge, MA, USA, in 2002 and 2007, respectively. Her Ph.D. thesis was on thin-film magnetism and spin-polarized tunneling in magnetic tunnel junctions under the supervision of Jagadeesh Moodera from the Francis Bitter Magnet Laboratory, MIT. She is the Director of Non-Volatile Memory Materials Research at the Research Division, Western Digital Corporation, San Jose, CA, USA, where she leads a team working on materials for magnetic random access memory technology and other exploratory projects. She first joined the company in 2011, when it was previously known as Hitachi Global Storage Technologies, to work on research on granular FePt media for heat-assisted magnetic recording. Prior to working in industry, she was a Distinguished Post-Doctoral Fellow, and later an Assistant Scientist, at the Center for Nanoscale Materials, Argonne National Laboratory, Lemont, IL, USA, where she studied emergent phenomena at the interfaces of complex oxide heterostuctures. Dr. Santos has played an active role in professional societies in the magnetism community, serving as a Secretary/Treasurer for the Topical Group on Magnetism and Its Applications (GMAG) of the American Physical Society, on the program committees of several magnetism and magnetic materials (MMMs) and international magnetics (INTERMAG) conferences, the Program Co-Chair of INTERMAG 2020, the Exhibits Chair of several MMMs and the International Conference on Magnetism, multiple terms on the MMM Conference Advisory Committee, and the Publicity Chair of the Magnetic Recording Conference. In 2009, she was awarded the L’Oréal USA Fellowship for Women in Science.
