The Database Reading Group has been meeting more or less weekly for about 25 years, first at OGI and now at PSU. We currently meet Fridays at 10:00-11:30am, and welcome participation by anyone on a regular or occasional basis. Instructions for signing up are on the group web page.

Research areas I work in include:

Data Streams. My work with data streams began with the NiagaraST project, which was conducted jointly with University of Wisconsin (Niagara page at UW). That work has been continued in the latte project looking at streamed and archived data, in collaboration with the Intelligent Transportation Systems Laboratory at PSU. A second aspect of this work is Mutant Query Plans, an alternative to conventional distributed query processing. I have also participated in research in data streams at Microsoft Research, in connection with StreamInsight.
Superimposed Information Management. Superimposed information (SI) is information placed over existing base sources in order annotate, link, reorganize, classify or otherwise enhance those sources. There have been a number of projects over the years developing or using SI, all in collaboration with Lois Delcambre. Most recently we have been looking at its use in the context of digital libraries, as part of the Ensemble project, which we call Canonical Structures. Past projects include are Sidewalk (joint with Virginia Tech and Villanova, Overcast and SPARCE (Superimposed Pluggable Architecture for Contexts and Excerpts).
Scientific Information Management. I participate on the Cyber-Infrastructure team the Science and Technology Center for Coastal Margin Observation & Prediction (CMOP) at OHSU. Data Near Here is the main project I’m pursuing with CMOP. I have been involved with the SciDB array database project since its inception, and am currently involved in a joint research project with Brown, MIT, Wisconsin and Washington. My main activity there is AGRIOS (A Generalized R Interface Over SciDB). SciDB is also a key component of the Intel Science and Technology Center for Big Data in which I participate. Together with researchers at Washington and Michigan, I am contributing to the SciFlex project, which seeks to provide “Database as a Service” for the long-tail of science. The main conduit for deployment of SciFlex results is SQLShare. Another area of work in scientific data management focused on forest canopy research, in collaboration with Judy Cushing at The Evergreen State College.
Declarative Programming: I participate in the resurgence of Datalog, mainly through collaborating on temporal and spatial extensions for distributed systems with Joe Hellerstein’s BOOM group.
