Title
-----
Research Scientist at the Northeast Parallel Architectures
Center - Syracuse University, NY.

Research
---------
My current research areas are:

[1] Combinatorial optimization methods: 
    This involve dealing with complex problems of routing 
    and scheduling, network design, and facilities
    location. Since there are no exact algorithms to deal
    effectively with these kind of problems, approximation
    algorithms are a good alternative. We have used 
    genetic-based optimization algorithms, tabu search
    (from AI), and annealing-based heuristics (from physics) 
    to tackle large-scale scheduling problems rather 
    successfully. One of my current research areas is in the 
    development of hybrid methods combining local search 
    and population-based, creating still more effective
    general purpose solution techniques. Why a hybrid of
    these two approaches? We know that population-based 
    methods are quite effective in finding regions of the 
    search space that contain solutions of high quality,
    while local search techniques are quite successful in 
    determining an optimal solution in identified good regions
    of the search space.

[2] Large-scale Collaborative Systems: 
    Involving net-based collaborative systems of community
    of agents. For this we make use of our knowledge in 
    message passing interfaces and active messages used
    for distributed (memory) systems.
    I have worked on a Java-based collaboration model that is 
    currently used for distance education, planning and
    scheduling.

[3] Large-scale Modeling and Simulation: 
    Involving commercially-sponsored work that I have worked
    on of computational fluid simulation and circuit simulations.

Education
---------
Bachelor of Science in Mathematics and
Computer Science, Univ. Michigan. 
Master and PhD of Science in Computer Science, Syracuse.
Will be completing my PhD by 7/1999.
