Doctoral researcher, Chair of Ethics of AI and Neuroscience, Technical University of Munich

I study what social media feeds show people about health and the brain, and what people actually watch.

I work on HARMONY, which studies health information on TikTok among young adults, using data they donate from their own accounts. My work combines computational text analysis, surveys and ethics. I am supervised by Marcello Ienca. From October 2025 to January 2026 I was a Fulbright Visiting Scholar at the Stanford Social Media Lab.

Research

What TikTok shows, and what people watch

Donated TikTok histories linked to surveys: health content and misinformation, served and watched.

“The brain” in public

How claims about “the brain”, ADHD and neurotechnology are framed online, and what neuroethics can learn from it.

Radicalization and misinformation

How movements build their narratives and how language changes as people move toward extreme positions.

Language models and how people get information

How large language models change clinical communication and the way people look up information.
