My name's Ethan. I am a postdoctoral fellow in the field of atmospheric science—that means I study climate and weather, whether on Earth or another planet. My job includes a great deal of programming, so I also work on open source software development in my free time. Some of this development work is related to a growing interest of mine: volunteer-contributed geospatial information in OpenStreetMap. Please take a look around at some of my software projects, teaching activities, and mapping interests.
