I enjoy learning mathematics but have a hard time in any programming skills. I have a BS in mathematics with a minor in Astronomy from EMU. I hope one day to work for NASA but that dream is quickly fading. Also I am w running/workout health nut and am currently training for the Marine Corps Marathon in October.

Professional Interests: interpolation. optimization
