Research Interests

Dr. Saraf’s training is in polymer science, optics and Silicon processing. In the past 15 years his research interest has been in interfacial properties of materials, nanometer scale devices & their processing and, more recently in biophysics and bioengineering. An author/coauthor of 31 US Patents and 64 scientific publications, the style of his research has been in basic sciences to solve practical problems.

Before joining UNL he spent ~5 yrs. in Virginia Tech and ~10 years at IBM’s corporate research lab – Thomas J. Watson Research Center at Yorktown Heights.

PhD/MS: Polymer Science, University of Massachusetts, Amherst
B.S: Indian Institute of Technology, Kanpur, India
