1. Generalized Mixed Integer Rounding Valid Inequalities for Mixed Integer Programming Problems (2006 - Present)

 

This research started as my dissertation at North Carolina State University. The paper based on this work was recognized as ’Finalist’ at 2006 INFORMS George Nicholson Student Paper Competition. The research has opened doors to several research avenues which we are currently pursuing. We have introduced a generalization of the theory of MIR inequalities. Using this generalization we have developed new families of MIR inequalities for general MIP problems and new families of facets for the finite and the infinite group polyhedra.

2. Optimization of Woodcutting Processes in Lumber Industry (2005 - 2007)

           

I worked on this project as a research assistant under supervision of Dr. Yahya Fathi at NC State University. This research was on the application of mathematical programming (including linear, integer, dynamic programming) in optimization of woodcutting processes. The project was supported by a STTR grant from the NSF (... read more)

 

 

3. Simulation Study of Natural History and Screening of Colorectal Cancer (2004-2005)

I worked on this research project as a research assistant under the supervision of Dr. Stephen D. Roberts at NC State University. This research was on study of natural history of colorectal cancer and cost-effectiveness of different screening methods and policies for it. The project was supported by the NIH (... read more)
