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:

Net Data Managment. One aspect of this work is data stream processing, which has been a focus of the NiagaraST project 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.
Superimposed Information Management. Superimposed information (SI) is information placed over exisiting 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. The two main current projects are Sidewalk (joint with Virginia Tech and Villanova), which looks at uses of SI in the context of digital libraries and teaching, and Overcast, which aims to further develop our SI models and technology. Our middleware for supporting use of SI by superimposed applications is SPARCE (Superimposed Pluggable Architecture for Contexts and Excerpts). Superimposed applications built using SPARCE include Sidepad and Mash-o-matic.
Health Information Technology. The RxSafe project is in collaboration with Oregon Health & Science University (Paul Gorman) and Samaritan North Lincoln Hospital (Karl Ordelheide).
Scientific Information Management. The Cormorant project is part of a larger grant looking at computer science issues in environmental observation and forcasting, mainly in the context of the CORIE system. That effort also included research on data product and forecasting support with Laura Bright. This line of work has flowed into the Science and Technology Center for Coastal Margin Observation & Prediction (CMOP) at OHSU. Another area of ongoing work in scientific data management has focused on forest canopy research, in collaboration with Judy Cushing at The Evergreen State College.
