Marco Bernardi

Marco Bernardi - CV

Marco holds a B.S. from the University of Rome “La Sapienza”, and a M.S. in Materials Science from the University of Rome “Tor Vergata” in Italy. He obtained his Ph.D. in Materials Science from MIT, where he worked with Prof. Jeff Grossman on novel materials and physical processes in solar energy conversion. He was a postdoc in the Physics Department at UC Berkeley, where he worked with Prof. Steve Louie and Prof. Jeff Neaton on excited electrons in materials. His group at Caltech focuses on computing the dynamics of excited states in materials, with applications to ultrafast optical processes and solar energy conversion. Marco has received a number of awards, including the 2015 Psi-K Volker Heine Young Investigator Award for electronic structure calculations, the Intel Ph.D. Fellowship from Intel, and the Endeavour Research Fellowship from the Australian Government, among others. His research has been featured in a number of magazines, including Wired, Nature, Scientific American, and Technology Review.
