Research

My main interests lie in decision making under uncertainty and optimization. Over the years, my projects, although always related to decision under uncertainty and optimization, have led me to explore varied domains and applications. The beauty of Computer Science is that it applies to many areas, … all? As a result, I always seek collaborations across disciplines.

My current work is in: 

  • Decision making for large dynamical systems under uncertainty, using reduced-order modeling of large computationally-intensive problems
  • Global optimization and constraint solving: symbolic-numeric algorithms aiming at enhancing the solving process, flexible/soft constraints
  • Combinatorial testing: t-wise covering test suites 

Other (related) research interests:

  • Interval computations: more accurate evaluation of interval functions, handling uncertainty
  • Multi-criteria decision making, and decision under uncertainty, combination with interval computations
  • Applications of constraints and optimization: e.g., bio-medical engineering, computer security, software engineering

Other current interests include (but are not limited to): non-square matrices, tensors, large-scale systems, and applications to: program verification, fuzzy measure extraction.

Some of my on-going research is as follows:

Some of my previously funded projects are: 

  • 1/ reduced-order modeling of large computationally-intensive problems (a project of Stanford’s Army High-Performance Computing Research Center — funded by ARL — 04/2013-12/2017)
  • 2/ global optimization and constraint solving (NSF CAREER project — 01/2009-12/2016)
  • 3/ prediction of experts’ decisions using Choquet integral and optimization, as well as argumentation networks and soft constraints (with Stefano Bistarelli, Uni. Perugia, Italy — funded by AAAS)
  • 4/ a Virtual GeoCaching Game (funded by Raytheon)

CONFERENCES ORGANIZATION

  • CoProD, Annually since 2008
  • NAFIPS’16, Annual conference of the North American Fuzzy Information Processing Society, to be held at UTEP, Oct. 31 to Nov. 4.
