Kenneth Crozier is Professor of Physics and Electronic Engineering at the University of Melbourne. This is joint appointment between the School of Physics and the Department of Electrical and Electronic Engineering. Prior to joining the University of Melbourne, Kenneth Crozier was a faculty member in the School of Engineering and Applied Sciences at Harvard University. He joined Harvard as an Assistant Professor of Electrical Engineering in 2004, and was promoted to Associate Professor in 2008. His research interests are in nano- and micro-optics, with an emphasis on plasmonics for surface enhanced Raman spectroscopy and optical forces, optofluidics and semiconducting nanowires. He has published in excess of 80 journal papers on these and related topics. He received his undergraduate degrees in Electrical Engineering (with first class honours, with LR East Medal) and Physics at the University of Melbourne. He received his MSEE and PhD in Electrical Engineering from Stanford University in 1999 and 2003, respectively. In 2008, he was a recipient of a CAREER Award from the National Science Foundation (USA) and a Loeb Chair at Harvard, an endowed position for junior faculty. In 2014, he was awarded an Innovation Fellowship from VESKI (Victorian Endowment of Science, Knowledge and Innovation) on his return to Australia. He is a Senior Member of the Institute of Electrical and Electronics Engineers (IEEE), of the Optical Society (OSA) and of the International Society for Optics and Photonics (SPIE).
