I completed my BS (2002) and Masters Degree (2008) from the
Computer Science Department at
Texas A&M University (TAMU) and I have been involved as a Research Engineer with the
Space Engineering Institute, the
Spacecraft Technology Center, the
Space Engineering Research Center, and
KAMU at TAMU.
My research interests include Machine Learning, Computer Vision, and Localization and Mapping for Robotics
Projects
-
Space Image Simulation and Sensor Testing - 2010
Developed an image simulation and calibration process for testing space-based sensors such as StarTrackers. Furthermore, we have conducted multiple tests of industry StarTracker prototypes and verified accuracy performances of attitude estimates.
Presented at AGI Satellite ToolKit Users Conference, Houston, TX, June 18, 2010
Presentation: (PPT) (PDF)
Video: STK-VSI Simulation Comparison (wmv)
-
Orbital Analysis of an Asteroid Tracking Spacecraft - 2010
Performed an orbital analysis of a spacecraft on a planetary mission to track the Apophis Asteroid. Also generated imagery simulating a camera onboard the spacecraft as it tracked Apophis using Dr. Daniele Mortari's Virtual Star Tracker Simulation Software.
Project Collaborators: Julie Sandberg, Brad Taylor, Carolyn McGraw

- Space Situational Awareness - 2008
The goal is to implement a detection mechanism that allows satellites in orbit to identify any approaching nearby objects, that can be utilized by currently deployed spacecrafts using only imaging sensors.
-
Camera Calibration for Star Identification - 2007
Evaluate camera calibration techniques and compare performance for inter-star angle measurements to aid in star identification.
