I am a Post-Doctoral Researcher in the PROLANGS group at Virginia Tech working for Barbara Ryder. I received the Ph.D. in Computer Science from the University of Nebraska - Lincoln. I got my B.S. and M.S. in Computer Science at Oregon State University. Prior to that I also attended Eastern Nazarene College.

Research Interests

I am interested in the field of software engineering, particularly focusing on issues in program analysis, testing and debugging. My advisors for my Ph.D. work were Gregg Rothermel and Sebastian Elbaum.

My Ph.D. Dissertation is on "Probing Analysis of Closed Components." As software has become more complex, it is increasingly common for applications to built by composing existing components. Oftentimes the person using the component has limited or no access to the source code, and in some cases even the exectuable code, for the components being used. Therefore we are developing a new dynamic black-box analysis technique called probing analysis. We have implemented probing analysis methodologies for web applications and services in our tool, WebAppSleuth.

I was the project leader of a port of the WYSIWYT family of techniques for spreadsheet dependability to Excel from September 2003 to June 2005 and built my own WYSIWYT Prototype, WAFFELL. I am also chief maintainer of the EUSES Spreadsheet Corpus.
