Teaching Statement

I'm Kurtis Heimerl. I'm a postdoctoral researcher at the University of California, Berkeley. I work on technology for developing regions with Professor Eric Brewer in the TIER group, as well as with Professor Tapan Parikh in the Represent group.

My thesis topic is the The Village Base Station (VBTS), a low-cost, low-power cellular system (based off OpenBTS). Our goal is to provide community cellular: local, community-owned cellular networks in areas without existing cellular coverage. Write-ups of our progress are here. We've started a company to commercialize this research, Endaga

I've worked on a wide variety of projects. Some examples include Umati, the crowdsourcing vending machine; PANTS/NetAPI, a modern sockets implementation; mPhone, a message-oriented phone system; and the Python implementation of the DTN bundle protocol.

My Master's thesis was a project called Metamouse (not to be confused with this), which allows for more equitable sharing of existing educational content. You can see a video demonstration here. I also gave a CITRIS talk on this research which you can see here.
