My research focus is, broadly speaking, on integrating data from
multiple sources into a single
dataspace. A dataspace is a next-generation data
integration platform built on the principles of data-coexistence and
pay-as-you-go integration. That is, in emerging areas such as
consumer-facing data management (i.e., the web) and large-scale
sensor-based applications, one cannot hope to tightly integrate all
data sources. Thus, dataspaces propose an incremental approach to
integration. Data encompassed by a dataspace is immediately
accessible through simple means such as keyword search. Over time,
through the combination of semi-automated techniques with judicious
use of human effort, a dataspace gradually incorporates more and more
understanding of its underlying sources.
Prior to this vein of research, I explored various aspects of
"bridging the physical-digital divide": integrating data captured by
physical sensor devices (e.g., RFID technology and wireless sensor
networks) into traditional data processing infrastructures. This work
was done as part of UC Berkeley's HiFi project, a distributed
hierarchical system for managing and processing sensor-based data
streams.
In the past, I have worked with the PIER group at UC Berkeley as
well as with the database
research group at the University of Wisconsin-Madison
researching P2P query processing
I was advised by Mike
Franklin.
