I am a Ph.D. graduand and research assistant working in the Information Extraction and Synthesis Lab with Professor Andrew McCallum. I successfully defended my Ph.D. thesis in June 2020 (degree to be conferred February 2021). I started in Fall 2012. Previously I was a software engineer and consultant at Mavenomics, Inc., developing business intelligence software for the financial sector, working on compilers, query engines, financial math and data visualization. I graduated from Duke University in 2010 with a B.S. in Mathematics and Economics. I received my M.S. in Computer Science from the University of Massachusetts Amherst in 2015, passing the Ph.D. candidacy portfolio With Distinction.

I interned with Paul Mineiro and Nikos Karampatziakis in the Microsoft Cloud Information Services Laboratory in the summer of 2014. I interned with Andrew Dai on the Google Brain team in the summer of 2015. I interned with George Dahl on the Google Brain team in the summer of 2016.

I am broadly interested in machine learning, natural language processing, and knowledge base construction, with an emphasis on probabilistic modeling. Areas of interest include representation learning, machine reasoning, structured prediction, and common sense knowledge, as well as applications in the biomedical and sustainable energy domains. I have been the fortunate co-author of multiple publications awarded Best or Outstanding Paper, since two is a multiple of one.

I am also an armchair PLT and functional programming enthusiast, and chief maintainer of the factorie machine learning toolkit.
