He received his doctorate degree from University of Hamburg, Germany in 2002 under supervision of Horst Weller. In 2003 he joined IBM Research Division at T. J. Watson Research Center as a postdoctoral fellow to work with Chris Murray on synthesis and electronic properties of semiconductor nanostructures. In 2005 he moved to Lawrence Berkeley National Laboratory as a staff scientist at the Molecular Foundry, newly founded DOE Center for Nanoscience and Nanotechnology. In 2007 he accepted faculty position at the University of Chicago. His research interests revolve around colloidal inorganic nanomaterials, spanning from synthetic methodology to device fabrication, with the desire of turning colloidal nanostructures into useful electronic materials.
