I am a PhD candidate at the University of Massachusetts Amherst in the College of Information and Computer Science. I work with Dr. Hong Yu in the Bio-NLP group. 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.
