PhD Candidate at Northwestern

Hello! I'm Julia Barnett and I'm a PhD student in Technology and Social Behavior, which is a dual PhD program in computer science and communications at Northwestern University. My advisor is Nicholas Diakopoulos, and right now we are researching the ability to predict what areas are impacted by artificial intelligence systems by only utilizing a couple short reviews of individual articles.

My research interests lie in algorithmic transparency and bias, ethical AI, NLP applications in social contexts, and the intersection of machine learning and music.

I completed a Master's Degree in Data Science at the Barcelona Graduate School of Economics in 2019, and I got my Bachelor's Degree in Business Analytics, International Business, and Marketing from Villanova University in 2018. Before my PhD I finished up a two year stint as a Senior Data Analyst at The Washington Post.
