Donal is a climber, cook, friend, dog-uncle, NSF graduate research fellow, and PhD student at the University of Maryland - College Park. His research interests include remote sensing of natural resources, computer automation of geoprocessing tasks, and modeling of ecosystem dynamics and carbon cycling. When he isn't working on his dissertation he is probably thinking about his dissertation, or maybe playing in the woods.
