Professor Thomas G. Robertazzi

Current Research:

  • Petascale, Exascale, Quantum and Machine Learning Computing:

The cutting edge of large scientific experiments is the generation of petabytes and exabytes of data. Such large volumes of data require advances in computing, networking, software and storage. There are spinoffs to engineering and business applications. Current work involves novel quantum computing architectures and also machine learning.

For the past 30 years work at Stony Brook has developed a very tractable model of scheduling divisible (partitionable) loads. The methodology is very well suited to integrating communication and computation issues. A world wide publication list on this topic up to 2014 is available at this web site. See Google Scholar for more recent years under "Divisible Load Scheduling"

  • Energy Research Computing:

A research effort into electric and other energy systems, Prof. Robertazzi was a co-P.I. on the Stony Brook Smart Grid Corridor project funded by LIPA and DOE.

Markov Chain Algebraic Topology:

This research seeks to gain an understanding of the fine structure of Markov chains, particularly in terms of conditions leading to tractable product form solutions. Its major successes were in (1) relating Markov chain structure and labeling to the chain flow structure and product form solutions (2) a new family of stochastic Petri net with product form solution (3) identifying recursive structure in certain non-product form queueing models leading to efficient solutions for equilibrium probabilities and (4) identifying a simple flow structure for non-product form networks.

Science and Engineering Living Learning Center:

Prof. Robertazzi was the faculty director of the Science and Engineering Living Learning Center at Stony Brook for about 13 years. This was an academic unit in the O'Neil residence hall that offered courses, minors and hosted speakers to bring an academic dimension to residential life. In fact over 150 speakers in science, engineering, the liberal arts and medicine gave presentations during Prof. Robertazzi's tenure as faculty director. Two minors, one in interdiscplinary science and engineering and one in technical leadership, were available to all Stony Brook undergraduates. Due to budgetary problems, the Center is now inactive. For his work in the Living Learning Center, Prof. Robertazzi received the Long Island IEEE section Papoulis Outstanding Educator Award in 2012.
