I work with the Jetstream project that runs on OpenStack, though I do not have any direct responsibilities with OpenStack itself.
Presently lead the Research Cloud Infrastructure team at Indiana University, which includes the NSF-funded Jetstream2 research cloud.
Previously worked primarily on the Jetstream project presently - www.jetstream-cloud.org - as the technical evangelist getting researchers and educators on the system. In this role, I'm the jack of all trades doing unix sysadmin work, cloud image maintenance, support, training, documentation, and anything else that needs to happen.
