I have been using Matlab for about 10 years now and am always impressed by its ability to constantly have something new for me to master.

Besides programming and engineering I love the outdoors, soccer, football, hiking, etc. If you have any suggestions for good trails around Northern Virginia, I'd love to hear them!
Professional Interests: spacecraft trajectory design, orbital mechanics
