I am an Instructor at the Mendoza College of Business at the University of Notre Dame, and an ABD PhD candidate at the University of Massachusetts Amherst in the College of Information and Computer Science. At UMass I was a member of the Bio-NLP group, working with Dr. Hong Yu. My research interests are in Machine Learning and Natural Language Processing. I am particularly interested in model evaluation and quantifying uncertainty, as well as applications in biomedical informatics.
Prior to UMass, I worked as a software developer at Eze Software in Chicago and as an IT Audit Associate for KPMG. I received my Master's Degree in Computer Science at DePaul University, where I worked on projects in Computer Science Education and Recommender Systems. I received my bachelor's degree in IT Management from Universty of Notre Dame, with a minor in Irish Language & Literature.

Below are a few projects that I've worked on, either as part of a class project or on my own time.
- GutenRecs: "More like this" book recommendations for Project Gutenberg. Final Project for ECT 584: Web Data Mining at DePaul
- An Analysis of Major League Baseball as a Social Network: Final project for CSC 495: Social Network Analysis at DePaul.
- Goodreads Right Click: A Chrome Extension for Searching on Goodreads. I wanted this to exist, so I built it.
