I like to play tennis, and used to play some soccer; while at CMU, I used to play soccer with the Robotics
team, the Viking Death Rats.
I was captain of the team for four years (we were Intramurals champions
in 1995). I also like to read, particularly French and Russian literature
of the ninenteenth century, but I have not been able to read much
since my son was born.
I work with probabilistic reasoning (standard probability and
theories that use sets of probabilities).
In my work on the
of sets of probabilities, I explore
inference and decision-making when probability values are
indeterminate/imprecise. You can take a look at the web
site of the Society for Imprecise
Probability Theory and Applications (SIPTA); I'm a founding
member of this society; I was the society's newsletter
editor, and then president for a while.
In the society's web site you will find information about several
symposia on the theme of imprecision and indeterminacy in
Regarding probabilistic reasoning, I have mostly worked with
Bayesian networks (developing algorithms, generation methods,
learning algorithms, classification techniques, applications in
medical and embedded systems).
The JavaBayes system
is my implementation of Bayesian Networks in Java.
The system is distributed under the GNU license; take a look
at it and enjoy the system. A related item is the

Apart from these issues, I have worked in a variety of problems,
mostly in Robotics and Artificial Intelligence; in the past
I have been particularly involved with mobile robots and their sensors.
A nice piece work was the development of robotic devices for the
disabled; one of my students got a prize from the Brazilian
Association for the Mechanical Sciences as Best Thesis (Master Level)
in Brazil back in 2003, for work on this device.
