Research projects

NiagaraST (2008 - )

NiagaraST is a Data Stream Management System. My current interests include the use of punctuations to enable query processing optimization opportunities, in particular, oportunistic responses. At larger scale, I am trying to define useful theoretical semantics for stream processing.

SPACKLE (2007 - 2008)

In collaboration with Dave Maier, Kristin Tufte, and Robert Bertini.

We are exploring mechanisms to provide on-line imputation of traffic data. We rely on archived measurements available in PORTAL.

Improving Maximum Daily Salinity Regressor Performance in CORIE (2004 - 2005)

In collaboration with Todd K. Leen.

Sensors deployed in the Columbia River (as part of an Environmental Observation and Forecasting System) collect different measurements, including temperature and salinity. The sensors are subject to biofouling, causing a steady decay in the maximum daily measurement of salinity. Previous work devised mechanisms to automatically detect the onset of the faulting event, comparing it to expected values.. My M.Sc. Thesis work looked at improving the performance of the salinity estimator.
