Summer 2008

In Summer 2008, I stayed on campus to make progress on my research. I have started work on a plug-in, named LexId, that infers patterns across identifers in copy-and-pasted code. I also have submitted some re-worked papers. Our research group, Software Engineering Research Laboratory (SERL), now has a website with a Bugzilla and CVS server.

Spring 2008

In Spring 2008, the semester began with communication between me and Valentin Weckerle of the Free University of Berlin in Germany. Valentin notified me that he was just finishing his Master's Thesis on his tool, CPC. We've discussed the possibility of reusing at least parts of CPC in CnP in the future. Ferosh Jacob, a Masters student at Clarkson, started working on a tool that makes inferences based on commonalities and differences between the structure of clones (Abstract, Slides). And, I have written my first full research paper.

Fall 2007

In Fall 2007, I started the semester by presenting my PhD Proposal, which was accepted by my PhD committee on Wednesday, September 5, 2007. I have now met all of my Qualifying Examination requirements, officially making me a PhD Candidate. This semester, I also presented my research in ECE Seminar, the ETX Workshop and the Doctoral Symposium at OOPSLA, and CS Seminar (which is my best presentation ever). Todd Deshane and I also created a new, simple example: Test. And, CReN users can now join our Google Group/Mailing List.

Summer 2007

In Summer 2007, I took credits on campus in preparation for my PhD Proposal (Qualifying Exam) in August/September. This included completing a prototype of CnP, named CReN, that demonstrates its use in "consistent renaming". I also read more of the related work and started posting summaries above and keeping a list of Code Examples. I also have three examples from the related work converted into Java: Bug Isolation, CP-Miner, and GCC Fortran. Finally, I have submitted to a number of conferences this summer.

Spring 2007

In Spring 2007, I started the initial development of the CnP tool, which is a plug-in written in Java for the Eclipse IDE. I learned the internals of Eclipse by studying its code base. For my EE564 class project, I focused on the incremental building provided by the Eclipse Builder. For my research, I started learning about the Copy and Paste actions as they relate to Eclipse's Java Editor and I continued studying parts of Eclipse's Java Compiler, including Abstract Syntax Trees (ASTs). I presented on the idea of this research during CS Seminar.

Fall 2006

In Fall 2006, my advisor Daqing Hou and I first defined this research topic into a paragraph abstract. I then worked on this topic more for my EE569 class project. In the absence of a suitable wiki and version control system, I simply kept a Research Blog of my progress. By the end of the semester, I completed a short "idea paper" that includes our goals and the expected contributions of this research and a summary of the related work in the field that deals with the detection of software clones and their errors.

Life Lessons And Getting A PhD

How Do You Know Me?

You might know me from a variety of things.

First, I was raised in the town of Amsterdam, NY. After that phase of my life, I moved to Potsdam, NY, where I've been a student at Clarkson University since 1998. Most of my journey since then can be found in my CV.

Todd Deshane and I have been together since July 2000. Todd Deshane is an author of the Running Xen book. Our Wedding is February 14, 2009.
