About Me:
Interested in Earth science and electronics and using one to help the other. I specialize in embedded systems that primarily make scientific measurement of water quality. I'm hoping to make measurements of water leaving reflectance and invert the results to make inferences about suspended and dissolved aqueous material dynamics. Ardupilot will get me there.
