Julia R. Greer

Julia Rosolovsky Greer is a materials scientist and pioneer in the field of nanomechanics and architected materials. Greer has earned many awards, such as being named a CNN 2020 Visionary, for her work investigating how materials behave at the nano-scale.

Greer has been a professor at the California Institute of Technology (Caltech) since 2007. She is also an Associate Editor at both Extreme Mechanics Letters and Nano Letters.

Greer was born in Moscow, Russia, and moved to the U.S. with her parents at the age of 16. Greer attended the Massachusetts Institute of Technology (MIT) for college, where she received a Bachelors of Science in Chemical Engineering and a minor in Advanced Music Performance in 1997. Greer then went on to receive graduate degrees in Materials Science and Engineering; she earned a Masters of Science (M.S.) in 2000 and Doctor of Philosophy (Ph.D.) in 2005, both from Stanford University. Between receiving her M.S. and Ph.D., Greer worked at Intel from 2000-2003. For her dissertation, titled "Size dependence of strength of gold at the micron scale in the absence of strain gradients," Greer worked with materials scientist William D. Nix studying the mechanical properties of nanopillars. After her PhD, Greer pursued postdoctoral studies at the Palo Alto Research Center (PARC) from 2005-2007.

Greer joined the Materials Science Department at Caltech in 2007 as an Assistant Professor; she received tenure and was promoted to Full Professor in 2013.

Greer has received much recognition and several career awards for her work. Her lab's early work has resulted in a new direction in nanomechanics. Her lab is now harnessing strategies in nanofabrication for applications ranging from improving lithium ion batteries to developing biomedical devices.

In addition to being a scientist, Greer is also an accomplished pianist. She took piano lessons starting at age 5 and has studied music at several institutions, including Moscow's Gnessin School of Music, the Eastman School of Music, MIT, the San Francisco Conservatory of Music, and Stanford University.

Greer also loves rollerblading. She will occasionally rollerblade to and from work and has even participated in a rollerblading marathon.
