CAREER SUMMARY

Since 2000 I have been working as full time researcher at Center for Composite Materials (CCM) of the

University of Delaware (UD). My work focuses on fundamental and applied research in the field of

composites and nanomaterials. Overall, I have more than twelve years of experience in fundamental

and applied research in the field of polymeric composites as well as training and supervising students

from different engineering backgrounds. I have also worked at Hanwha L&C as product development

leader for one year. My responsibility focused on development of new composite materials for high

strain rate automotive applications. I have 26 research papers in various international journals and

conferences.
