Biography

Seyed Sadeghi received his PhD in 1999 from the University of British Colombia and MSc from the University of Toronto in 1993. He was a National Science and Engineering Research Council of Canada postdoctoral fellow at the University of Toronto before joining industry in 2001, as a materials and laser designer. In the year of 2005-2007 he was with McMaster University as senior research scientist before joining UAH as a faculty member in 2007. His research interest include nanophotonics, energy transfer in hybrid inorganic-biological nanostructures, plasmonic devices, and applications of quantum mechanical processes for device applications. He has published more than 118 scientific papers in peer-reviewed journals regarding quantum optics of nanostructures, nanosensors, quantum devices, plasmonics, and quantum coherence processes in atomically thin semiconductor structures.
