My research includes work in reliable high-speed networks and reliable distributed systems. Now, I am working on a tool, called NFTAPE, for developing and executing automated fault injection experiments on fault tolerant distributed systems. NFTAPE takes a new approach at looking at how fault injection mechanism are developed in order to reduce the time and cost of creating or porting new ones. These fault injection mechanisms can then be plugged into NFTAPE to be used in fault injection experiments.

The following publications describe some of the research I have done: (see copyright notice.)

Resume

Hey look! My hometown (Vernon, Connecticut) is on the web.

Besides research, I am an advisor for Alpha Phi Omega, a national co-ed service fraternity.

And, maybe one of these days I'll get back into Ballroom dancing.

Other hobbies include:

• music (I play Bass Guitar, Guitar, harmonica, et. al. -- blues, rock, jazz, classical, etc. (basically anything but rap and pop music))
• animation (Looney Tunes, Animaniacs, Tiny Toons, South Park, etc.)
• cooking
• converting coffee products into source code

Emacs is my text editor of choice.

I am registered linux user #111221.

Here is a link to some work from a class project about microkernels

In another class I did some work on analyzing recovery blocks

This past summer, I worked at Tandem Lab, part of Compaq in Cupertino, CA. In past summers I work at the Jet Propulsion Laboratory in Pasadena, California. My job there involved the dependability of distributed applications. I've also analyzed a Myrinet network which is being considered for use as an interconnect in a super computer in space crafts. This word was part of a joint venture with the Paradise group at Caltech. Before that, I did AI programming for Schenley Park Research and for the Auton project at CMU.
