Bio: (CV) 

Before joining the University of Houston, Dr. Pâris was faculty at Purdue University and the University of California, San Diego.  He received his Ingénieur Civil degree from the Université Libre de Bruxelles, Belgium, his Diplôme d'Etudes Approfondies from the Université de Paris VI, France, his Licence et Maîtrise en Informatique from the Facultés Universitaires de Namur, Belgium and his Ph. D. in EECS from the University of California, Berkeley.

Courses Taught:

• COSC 1306: Computer Literacy for Science Majors (fall 2011 and ???)

• COSC 4330: Fundamentals of Operating Systems (spring 2012)

• COSC 6360: Operating Systems (fall 2011)

• COSC 7360: Advanced Operating Systems (spring 2011)

Research:

My background is in applied performance evaluation. I look at problems where the choice of the right policy has a direct impact on the performance of computer systems.  Depending of the problem,  my co-authors and I have used probabilistic models, discrete-event simulation,and/or trace-driven simulation. My current areas of interest include:

• Data survivability in storage systems:
  Many organizations now keep on line vast amounts of data for very long periods of time. We must find ways the most efficient to protect them against disk failures. 

• Video streaming and video on demand:
  I am currently interested in client-assisted distribution protocols.

I still have openings for one or two master's or doctoral students desirous to take me as an adviser but cannot offer any funding.
