Before coming to UMass, I worked for an internet auction startup, the NLP group at the University of Sheffield, and a cultural heritage digital library, the Perseus Project. I have a particular interest in historical texts and languages.
I am currently chief maintainer for the MALLET Machine Learning toolkit. I organized the NorthEast Student Colloquium on Artificial Intelligence (NESCAI) at UMass in 2010 along with Sameer Singh. I ran the UMass Machine Learning and Friends lunch series for two years.
