He is leading the Infosphere project, part of the DARPA Information Technology Expedition program. Infosphere is a joint project between Georgia Tech and OGI, plus a number of other collaborators. Infosphere builds on his previous and ongoing research interests. First, he has been working on next-generation operating system kernels to achieve high performance, adaptiveness, security, and modularity, using program specialization, software feedback, and domain-specific languages. This area has included projects such as Synthetix, Immunix, Microlanguages, and Microfeedback, applied to distributed multimedia and system survivability. Second, he has been working on new data and transaction management by extending database technology. This area has included projects such as Epsilon Serializability, Reflective Transaction Framework, and Continual Queries over the Internet. His collaborations include applications of these techniques in scientific research on macromolecular structure data, weather data, and environmental data, as well as in industrial settings. He has published more than 25 journal papers, 90 conference and refereed workshop papers, and served on more than 40 program committees, including the co-PC chair of SRDS'95, co-general chair of ICDE'97, and co-PC chair of ICDE'99.
