Ranga Prasad

Prasad received his B. S. in Electronics & Instrumentation Engineering (2004) from the University of Madras (Chennai, India).

He completed his M.S. degree in Micro-Electronics & Photonics from University of Arkansas, Fayetteville (2007) with his primary research based on Growth and charachterization of GaAs quantum dots on SrTiO3 thin films

While a student at U of A, He worked as a Research Assistant, in the Physics Department under the guidance of Dr.Greg Salamo. He also worked as a Graduate Assistant for the micro-Electronics & Photonics Program and as Teaching Assistant for the course 'Intra/Entreprenuership of Technology' at the Sam M.Walton College of Business
