Current Research Topic: 

• Decision Support Models for Design of Reliable Distribution Networks
  Developed a novel methodology for reliable transportation network design. The methodology determines the optimal
  network topology, disposition of supplier back up, and allocation of finite supplier fortification resources to obtain
  maximal reliability. The problem was formulated as a nonlinear MIP. The developed solution algorithm is capable of
  solving large-scale problems and is about 200 times faster than the ILOG CPLEX solver. The optimal transportation
  network design results in significant savings when compared with network designed by traditional methods.  
  Software and programming language: C++ and CPLEX.


• The Optimal Design of Water Supply Systems for Energy Efficiency
  Lead a multidisciplinary team of researchers to identify the sources of energy used by water supply systems using a
  novel hybrid analysis. A large-scale MIP model was developed to minimize the total energy consumption by determin-
  ing the optimal locations of the water treatment facilities, pumping stations, storage facilities, and water distribution
  channels. The findings of this research can be used to improve the efficiency of water supply systems in the Tampa
  Bay area. Funded by The 2009-2010 Graduate Student Challenge Grants: Building Research Partnerships Across Disciplines, awarded by USF;
  Software: CPLEX for Linux64bit, C++ with Linux;
  Team Composition: Industrial Engineering, Computer Science, Environmental Engineering and Geography.
