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 research interests lie in algorithmic ethics, algorithmic impact, reducing the sociotechnical harms of algorithmic systems, and deep generative audio.

I'm advised by Nicholas Diakopoulos, and right now we are researching different areas in the ethical AI space with a focus on algorithmic impact. We most recently explored how to utilize large language models (LLMs) such as GPT-4 to simulate the effects of policy through scenario building. Prior to that we focused on the ability to anticipate societal impacts of algorithms through mediums such as crowdsourcing. Currently I am working with Bryan Pardo to build an interface that uncovers the influences of generated pieces of music to provide a path for the end-user to move from ignorant appropriator to informed creator. I also work with Ágnes Horvát, investigating the intersectional penalty of gender and ethnic diversity of scientific teams on success in scientific publications and also with

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.
