Robert earned his PhD in Applied Physics from the Colorado School of Mines in 2007.  He focused primarily on diode laser bar optical trapping within microfluidic systems.  His research culminated with a palm-sized concept device using diode laser bars, optically written waveguides and microfluidic systems capable of sorting particles based on a variety of optical signatures as well as measuring cell deformability.

Robert Joined NFCR in January of 2008 and began working on acoustic and optical manipulation and interrogation of cells.  He is currently investigating methods to rapidly sort particles up to 1mm in diameter as well as acoustically measure cell deformability.
