Dr. Ozkan is a Professor of Mechanical Engineering at University of California, Riverside since 2009. He was an Associate Professor from 2006 to 2009 and an Assistant Professor from 2001-2006. Between 2000-2001, he was a consulting Professor at Stanford University. He received his Ph.D. in Materials Science and Engineering from Stanford University in 1997. His advisors were W. Nix and H. Gao. Dr. Ozkan’s areas of expertise include CVD and MOCVD of graphene, III-V, IV and II-VI materials; growth of hierarchical and multilayered nanostructures; nanoelectronics; energy storage technologies; nanopatterning for beyond CMOS. He organized and chaired 14 scientific and international conferences, including the MRS symposium titled "De Novo Graphene" in April 2014 in San Francisco, CA; and has given more than 100 presentations worldwide. His important contributions include: the first time growth of hierarchical three dimensional graphene nanostructures [1,2]; development of a unique high-throughput metrology method for large-area CVD grown graphene sheets [3,4]; doping and functionalization of CVD grown and pristine graphene layers [5-6]; study of digital data transmission in graphene and InSb materials [7-8]; memory devices based on inorganic/organic nanocomposites [9], novel lithium-ion batteries based on silicon dioxide nanotubes [10]; fast charging lithium-ion batteries based on silicon decorated three dimensional nano-carbon architectures [11]; and high performance supercapacitors [12] based on three dimensional graphene foam architectures.
