this summer.I have spent the last several years working with Ralph Johnson. It is not coincidental that his interests are similar to mine. My research interests are in the area of object-oriented programming and design. In particular, I am interested in refactoring object-oriented systems, especially how it pertains to the evolution of frameworks, and the application of patterns. Most of my work has been done in Smalltalk.
Bill Opdyke's thesis discussed the notion of refactoring and presented several refactorings that he had examined in C++. A majority of my work has been working together with John Brant to develop the Refactoring Browser. This tool allows you to perform refactorings on production-level Smalltalk code quickly and safely. We are always looking for suggestions on ways to improve it. Another component of this package is Smalllint. Smalllint is a system to detect common bugs and style errors in Smalltalk programs.
Designing frameworks is difficult. In fact, I believe that they are so difficult, that they can only be designed by building examples and generalizing the example code into the framework code. Brian Foote is one of the pioneers of this belief. Ralph and I have presented a course on developing frameworks as various conferences. We have written a pattern language to describe this process.
I was one of the original group members who reviewed the Gang of Four book as early as 1993. I am amazed at how quickly the idea has become popular. I was the conference chair of PLoP '97 (and survived). I continue to look for patterns of refactoring code.

I gave Ralph's framework tutorial at Smalltalk Solution '98.
When I'm not doing research, I am a smalltalk consultant. My past jobs have included work with Hewitt and Associates, Abbot Pharmaceuticals, Sprint, and Lucent Technologies. I am available for mentoring, design, refactoring, and development.
Along with my paying jobs, I also develop and maintain a couple of freely available software packages. I am one of the coauthors, along with John Brant, of the Refactoring Browser. Justin Graver and his students developed T-Gen, the smalltalk parser generator. They are no longer supporting it, so I have adopted it, since it is such a great tool.

Technically, we're not allowed to have pets in our apartment, but we have a couple of Chinese Water Dragons, Puff and Zoe, and a savannah monitor named, Mr. Peterson, and a uromastyx named Art (you call that Art?). They live in enclosures, so we classify them as furniture.
If I have a hobby, it would have to be collecting and playing board games, and in particular, German board games. I also enjoy backpacking and many other outdoor activities.
I've always been interested in weather. I've even taken several
meteorology courses, but it remains a hobby at best. Here are some of
the better weather sites.
