Julia R. Greer received her undergraduate degree in chemical engineering (with a minor in music) from MIT, after which she worked as an intern in the Components Research Department of Intel while pursuing a M.S. in materials science at Stanford, where she built a novel X-ray diffractometer in order to study mechanical properties of materials in computer microprocessors. After working at Intel's Mask Operations Department for two years, Julia received a Ph.D. in materials science and engineering from Stanford, where she studied size effects in plasticity of metals at the nano-scale with Professor William D. Nix. Prior to starting her appointment as a faculty member at Caltech in June of 2007, Greer was a post-doctoral fellow at PARC, Palo Alto Research Center, from August of 2005 until May of 2007. In order to broaden her expertise, she worked on investigating the behavior of organic semiconductor-thin film transistors (OTFTs) as well as nano-ink-derived metals for jet printing in flexible electronics with Dr. Robert A. Street. Throughout her scientific career, Julia has also been pursuing her "secondary career" as a concert pianist, having studied at the Moscow's Gnessin School of Music, the Eastman School of Music, the San Francisco Conservatory of Music, and at Stanford. She has performed numerous solo recitals (most recently at Caltech's "Off the Clock" event in 2011), chamber music concerts (most recently in Lagerstrom Series at Caltech with violinist C. Kovalchik), and as a soloist with an orchestra.
