Lia C Bozarth

6th Year PhD Candidate at University of Michigan, School of Information (UMSI)


I'm broadly interested in data science for social good, and I'm particularly interested in researching complex sociotechnological systems with vast user-generated content. Thus far, I have published numerous manuscripts in the field of misinformation and online political communications. My projects rely on extensive social media datasets and a diverse range of computational methods including natural language processing (topic modeling, word2vec, entity extraction, NLTK, BERT), network analysis (centrality, network cascade, network inference, motifs), machine learning (scikit-learn, Tensorflow), and statistical analysis. My PI is Ceren Budak.

Social Media:


I grew up in the West Coast, and earned my bachelors in Computer Science from the University of Washington, Seattle. I then worked at Amazon and Google as a full stack software engineer for a few years. I'm currently a 6th year doctoral candidate at the University of Michigan, School of Information.

Outside of work, I enjoy basketball, badminton, running, weight lifting, horror films, Dungeons and Dragons with my close friends, and teaching my pets new tricks. I have also solo backpacked in Asia and Europe for half a year, and contemplated being a wandering comedian for a time.
