Yep, I'm on Substack: to make my research accessible and useful, I'll translate my work into digestible posts that explain how I study the local news market at scale, through text mining, to ask questions about media ownership, news deserts, and democracy: shorturl.at/q3VKI

Last week, I presented my recent paper on memorization and hallucination in LVLMs at @l2m2workshop.bsky.social #ACL2025. TLDR: model memorization may be more prevalent over image sources vs. text! Details here: aclanthology.org/2025.l2m2-1....

Excited to share our FAME method for news identification: Fingerprint-to-Article Matching for Events from a DB! We use it to study news coverage of disasters and conflicts (w @brenocon.bsky.social @ethanz.bsky.social). Check out our talk and poster at @icwsm.bsky.social!🧵👇 arxiv.org/abs/2506.12925
