Over the span of my 33 year academic career I worked on parallel
and distributed computing, with a concentration on parallel and
distributed simulation, simulation topics in general, and message
ordering guarantees in distributed networks (employing logical
time systems --Isotach Networks). My research led to the
construction of two separate pieces of special purpose hardware. I
conducted and published first known work on methods for creating
multi-resolution models, and separately on concurrent writers in
concurrent caches and distributed shared memory. More
recently I explored managing uncertainty in simulations, computing
for the blind and the design of a domain specific language for
describing and statically analyzing the observable behaviors of
emitters. I supervised 65 graduate degrees, including16 PhD
students, and published 100 refereed papers. I supervised
many undergraduates on research as well, including a Computing
Research Association national runner-up (second place), Erin
Carson, on the employment of Dempster-Shafer techniques for
uncertainty exploration in simulation. Many of my
undergraduate advisees were finalists in the Engineering School's
undergraduate thesis competition (URDS) and there were two
The bulk of my work was collaborative, because that's how I love
to work. I am forever grateful to the very talented and
devoted students with whom I worked during my career at UVa.
My students, I bask in your successes.
Officially UVa says I'm retired (includes gold parking pass to
park anywhere on grounds and an office), but that's only from the
university. I'm hardly retired. There's life after
professoring. My current CV reads: Professor Emeritus,
Expert, Expert, Expert. I continue to work part time for the
Army as an expert in modeling and simulation and software
analysis. I work with Shine S&T identifying new
intellectual property in M&S within the state of Virginia on a
small business grant. And I've become an expert in
identifying prior art and testifying about it in patent lawsuits,
working with the largest patent law firm in the world. (See
some of my work on patents 6631449, 6918014 and 5825891 at the PTAB.)
On the side I keep advocating for passenger rail. Someday
I'll get to all of that wood I harvested from fallen trees around
Albemarle County since the 90's, and make some furniture.
