Education:

Ph.D. Candidate, Mechanical Engineering, (expected 2013), U. Pennsylvania
M.S., Mechanical Engineering, (2004), Villanova University
B.S., Mechanical Engineering, (1998), Sharif University of Technology

Research Interests:

I am new to the field of nanotechnology. Currently I am learning preliminary techniques and tools like atomic force microscopy (AFM), transmission electron microscopy (TEM), etc., to get familiarized with the tools needed to work in this field. I'm also working on characterization and optimization of UNCD AFM probes using AFM, TEM, and finite element analysis. In the long term I will be studying nano-scale wear and nano-manufacturing of diamond materials.
