Dr. Kristin Tufte is a Post-Doctoral Research Associate in Computer Science
and Civil & Environment Engineering. Dr. Tufte's area of specialization is database systems. In particular, she studies techniques for processing data
streams such as network (Internet) traffic, environmental sensor readings, traffic sensor data, and telephone call records. Interesting
challenges presented by these types of data are the "unending" nature of data streams and disordered, dirty, skewed, and bursty data. Dr.
Tufte is interested in applying data stream technology to Intelligent Transportation Systems (ITS) data streams such as loop detector data and
bus dispatch data in an effort to provide improved traffic measurements to ITS professionals. Dr. Tufte is currently involved in the
Portal project which is archiving ITS data for the purpose of improved traffic
assesment and modeling. In her previous research, Dr. Tufte has been involved in the development of two large database systems: most recently,
the Niagara Stream Query Engine and previously the Paradise
GIS Database. |

Spicer
moved to Portland from New York to seek out a degree in Engineering
from Portland State University, and also to seek out new job
opportunities on the West Coast....well kinda! That is the response
he gives his parents and any academics that may ask. His real reason
for moving to the North West was his love of snowboarding, mountain
biking, and white water kayaking. Along with working on the PORTAL
project, Spicer has his hands in many other projects both on campus
and in industry. Spicer's "real" job is he works as a property
manager/IT consultant. Yes, rather odd combo, you will have to
corner Spicer to find out more about this broad career that he has.
Note: he tends to get a little more chatty if you offer to take him
out for a drink! Spicer plans to finish up his undergrad in computer
science, and a minor in business, any day now and then plans to
continue in a masters in computer science at Portland State
University.
