I'm a sort of freelance researcher and software developer, currently working full-time as a contractor for a new company called 3Plus1 Technology. My technical interests include computer architecture, computer arithmetic, operating system kernels, and compilers. I continue to update my résumé on-line, in case you're curious.

Besides work, I can sometimes be found in activities like racquetball, backpacking, ultimate frisbee, and windsurfing. I dabble in photography and graphic art, and I study history on the side. I've also gotten to be a pretty serious foosball player. Although I'm not so good at playing the harp (harmonica), I still practice that occasionally, too.

Interests

	Pictures of Roman ruins in Italy. Over 150 photographs from my first trip to Europe, way back in 1997.
	Great films.

Technical Projects, Past and Present

	SoftFloat and TestFloat. SoftFloat is a software implementation of the IEEE floating-point standard. TestFloat is a program for testing whether a floating-point implementation conforms to the IEEE standard.
	The Garp processor. Garp is a hypothetical general-purpose microprocessor that includes on-chip ``reconfigurable hardware'' as an added computing device. Garp was the topic of my dissertation, and a project of the BRASS Research Group.
	Algorithmic exception handling. By algorithmic I mean the common kind of exception handling now supported by many programming languages. My Master's work was in this area.

Documents

	Publications and other documents.
	Résumé.
