I was general chair for the 2011 Conference on Scientific and Statistical
Databases (SSDBM 2011) in Portland,
I am part of the Data and Information
Management Laboratory (Datalab) at PSU.
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
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
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.
