About Me




Work Experience


I am working on applications of deep learning and natural language processing (NLP) in diffrent problems, such as user modeling and text modelind, etc.

I was a member of the Talos team of the Security Business Group. Using the Big Data technology and machine learning techniques I contributed to designing, building, and improving Cisco’s security appliances and technologies.

I performed applied research on a variety of predictive analytics problems coming from different industries such as healthcare and finance. I developed predictive signals and machine learning models for problems such as hospital readmission predictions for a major U.S. hospital chain and predicting the probability of credit default for a major U.S. bank.

My research was on parallel branch and bound algorithms for mixed integer linear programming problems and also primal heuristics for these problems. I developed two novel primal heuristics for integer programming, namely Randomized Rounding and Pivot-and-Fix. These primal heuristcs have been in a part of COIN-Cbc since 2009.

Under the NSF grant for Cyberinfrastructure Experience for Graduate Students (CIEG) I did research on high performace computing for mixed integer programming. I developed PMaP (Parallel Macro Partitioning) which is a parallel solver for mixed integer programs on shared-memory parallel computing frameworks.

As a PhD student, I performed theoretical and computational research on different aspects of mathematical optimization including mixed integer linear and nonlinear programming, parallel computing in mathematical programming, and global optimization. I also worked on the application of parallel computing in mixed integer linear programming. My PhD thesis was on theoretical and computational aspects of linear convexifications for multilinear function in optimization problems. I studied the strength of convex relaxations for nonconvex functions in general and multilinear functions in specific.
