Senior Statistical & Research Technology Specialist
UIT Research & Geospatial Technology Services
16 Dearborn Road
Somerville, MA 02144
What I do:
I provide statistical computing and consulting assistance to faculty and graduate students for research computing and instructional projects. In addition, I provide assistance for applications found on Tufts Linux cluster and BioInformatic computational servers.
Education & Background:
My training includes a B.S. in Mathematics and Physics. In addition, I spent 3 1/2 years in the Ph.D Mathematical Statistics Program, Dept. of Mathematics at SUNY Albany.
Topics of particular interest to me include Bayesian Statistics, Robust Estimation, statistical graphics and their applications to data mining.
