Excited to share my 1st grad school preprint w/ @eriknook.bsky.social
We review how AI is used in mental health research & treatment (from detecting symptoms w/ language to powering therapy chatbots) and highlight ethical/safety issues w/ rapidly bringing AI into this space.

I've had a missile blow up next to my airplane, been shot at dozens of times by anti-aircraft fire, and launched into orbit — all for my country. I never thought I'd see a President call for my execution.
Trump doesn’t understand the Constitution, and we're all less safe for it.

With current technology, it is impossible to tell whether survey respondents are real or bots. Among other things, makes it easy for bad actors to manipulate outcomes. No good news here for the future of online-based survey research
