Thomas Begin

I am an Associate Professor at Université Claude Bernard Lyon 1, and a member of the LIP lab.

I am a member of the Dante team that is also an Inria project-team.

My research is in the area of performance evaluation, queueing theory, stochastic modeling as applied to networks and computer systems. I am particularly interested in applying stochastic modeling and queueing theory to practical problems in computer systems.

Together with Alexandre Brandwajn, we deployed a web application that produces the solution of certain queueing systems using our resaerch material (e.g., G/M/c-like, M/G/1-like, and M/G/c-like queues). Click here to access the tool.

During the 2015-2016 academic year, I was on research leave at DIVA lab - University of Ottawa (uOttawa) - Canada. This leave was funded through a CNRS grant.

Current and past collaborators with whom I was privileged to work with:

Funny citations I like about Computer Science
  • "Sometimes it pays to stay in bed on Monday, rather than spending the rest of the week debugging Monday's code." - Christopher Thompson
  • "Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it." - Brian W. Kernighan
  • Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the universe trying to build bigger and better idiots. So far, the universe is winning." - Rick Cook
