Profile

I am currently in my second year of pursuing my Ph.D at Rutgers University. I am working on motion planning algorithms that can handle complex dynamics.

I originally was attending school at the University of Nevada, Reno, where I earned my Bachelor's degree in Computer Science. My senior project was a development middleware for implementing obstacle avoidance algorithms on the Segway RMP platform. This project was created for the purpose of helping future project groups get into development quickly, along with easily integrating hardware and software. Our group was able to implement a simple obstacle avoidance algorithm, Vector Field Histogram, using this framework. Also implemented is an obstacle detection program that can estimate an obstacle's velocity.

During the summers of 2011 and 2012, I was a summer intern at NASA Ames Research Center. During that time, I implemented Field D*, an extension of D*, for rover navigation. This extension provides a mechanism to move anywhere in a grid representation, whereas D* would only allow to move between grid cell corners. Also, I explored possible extensions and data structures for implementing Field D* for grids that contained cells of different sizes.

I am now a NASA Space Technology Research Fellow working on providing efficient planning methods for planetary rovers.
