I'm a fifth year Ph.D. student at the University of California, Santa Barbara, studying cloud computing. Some projects I'm involved in:

AppScale - an open source implementation of the Google App Engine APIs. Runs App Engine apps written in Python, Java, or Go over Amazon EC2, Eucalyptus, Xen, or KVM.

Active Cloud DB - a software-as-a-service that exposes a REST API to any of the databases that AppScale supports (e.g., HBase, Cassandra, MongoDB) or the Datastore that App Engine supports.

Neptune - a domain specific language that automatically configures and deploys high performance computing apps over AppScale. Run your MPI, MapReduce, X10, and other codes automatically over EC2 without needing to know how to start them and configure them!
