Research Interests

Operations Research with emphasis on large scale and computationally demanding dynamic programming problems; optimal path finding in time-dependent networks; optimal path finding in a time and space evolving anisotropic medium; and optimal routing of nonholonomic systems.
Applications include vessel, autonomous vehicles and robot routing.
Also interested in the intersection of transportation and logistics with energy conservation.

Research Experience

Graduate Research Assistant to Dr. Robert L. Smith   -  January 2005 to present
University of Michigan
Optimum Vessel Performance in Evolving Nonlinear Wave Fields,
Office of Naval Research - MURI grant

- Analyzed minimum travel time problems for anisotropic speed functions, found analytical solution for time homogeneous case.
- Studied dynamic programming application to time-dependent networks and effective techniques to improve its computational efficiency.
- Integrated system dynamics and constraints for optimal path finding problems.
- Developed efficient dynamic programming model to solve large scale and computationally demanding path finding problems.

Undergraduate Researcher to Dr. Donald W. Hearn   -  Summer 2004
University of Florida
Circle Covering Points Problem

- Analyzed various algorithms (Welzl, Elzinga-Hearn, etc.) to solve "Circle covering points" problem.
- Used MatLab and FORTRAN to analyze and compare computational complexity of the algorithms. 

Summa Cum Laude Thesis - July 2003 to July 2004
