I am a doctoral student in the Department of Computer Science at the University of New Hampshire where I work with Professor Wheeler Ruml in the UNH Artificial Intelligence Group. My research interests are in algorithms for planning and autonomy.

I completed my MS degree in computer science in 2020 with research in the area of network time synchronization and one-way latency measurement with Professor Radim Bartoš.

Here is my CV.

Current Research

Planning with a Known Deadline (Fall 2020--present, Prof. Wheeler Ruml): Investigating online prediction of future search effort in order to take greatest advantage of planning time remaining prior to a known deadline.

Class Projects

Planning with a Known Deadline (CS 931: Planning for Robots, Fall 2021, Prof. Wheeler Ruml): Comparing different heuristics and error models for use in a deadline-aware version of beam search.
Data-Driven Dynamics Model for a Boat (CS 850: Machine Learning, Spring 2021, Prof. Marek Petrik): Used k-nearest neighbors to learn a data-driven model from physics-based simulated data as proof-of-concept for use in model-predictive control.

Previous Research

Motion Planning with Dynamic Obstacles (Fall 2020--present, Prof. Wheeler Ruml): Implementing offline anytime BIT* and integrating into a field-tested ROS-based autonomy stack for a surface vessel for performance comparison with alternative realtime algorithm.

Time Enough: Synchronization for Latency Measurement, MS thesis, University of New Hampshire, 2020 (advisor: Radim Bartoš): Empirical investigation of relative robustness of several network time synchronization methods with respect to asymmetric latency and asymmetric jitter for the purpose of one-way latency measurement.
