Current Research

At Florida Institute of Technology, I worked on the National Science Foundation (NSF) Grant Project in collaboration between Systems Research on Intelligent Design and Engineering (STRIDE) Lab at Florida Institute of Technology and Clemson Engineering Design Applications and Research (CEDAR) Lab at Clemson University for my PhD dissertation. This research will explore the evolution of design requirements throughout the design process utilizing network models and data analytic techniques.

Publications

• Dissertation: Computational Support for Measuring Requirement Change Volatility in Complex System Design.
