I completed my PhD in September 2011. I was advised by Elaine Cohen. I am currently a Research Scientist at Siemens Corporation, Corporate Research & Technology. My research interests include geometric feature extraction and shape analysis using B-Spline techniques for applications in computer-aided design and engineering (CAD) and medical imaging. I have also worked on virtual environments for reverse CAD engineering.

I was a recipient of the 2010-2011 University of Utah Graduate Research Fellowship.

	Reverse engineering is a time-consuming and technically formidable process that is increasingly becoming an economic imperative due to replacement costs. The {\em Multiple Engineering Resources aGent Environment} (MERGE) system, introduced in this paper, is a new approach toward reverse engineering whose architecture and modules are driven specifically by the requirements of {\em legacy engineering}. Legacy engineering scenarios presume availability of multiple (possibly incomplete or inconsistent) sources of information, lack of digital descriptions of the parts, constrained time restrictions and need for significant domain knowledge expertise. The reverse engineering process must yield modern CAD models capable of driving state-of-the art CAM processes. The MERGE system aims at making the reverse engineering process more effective, using both intuitive interaction and visualization as key components, by enabling quick identification and resolution of inconsistencies among various resources in a unified environment. The MERGE system also aims at simplifying the reverse engineering process by integrating various {\em computational agents} to assist the reverse engineer in processing information and in creating the desired CAD models.
