We're hiring a CS postdoc for the STELLAR project funded by @wellcometrust and @OpenAI to build AI-powered patient simulations for mental health clinician training. You'd specifically be developing Conceptor-based steering methods for open-weight LLMs to simulate psychiatric symptom presentations with precise, composable control. The position is based at NYU Stern with appointments at Penn CIS and the Linguistic Data Consortium. You'd work with an amazing interdisciplinary team across CS, Psychiatry, and Public Health!

Paper now out in ACM #CHI2026! Spoken English proficiency drives economic mobility for low-income Indian youth, but opportunities to actually speak English in school are scarce. Large classes, teachers without adequate proficiency, and textbooks in English but instruction in local languages. And with generative AI making polished written English cheaper, the relative value of spoken fluency is only rising. New work led by Sneha and @viviennebhchi deployed a voice-based chatbot for conversational English practice across four low-fee Delhi schools. Through a six-day field study involving 23 students, 6 teachers, and 5 principals, they tracked what actually happens when this technology is implemented in resource-constrained multilingual classrooms. Although this was a qualitative study, the observed gains in student-initiated questions were substantial: from 36% on Day 1 to 65% by Day 5. Students who started nervous and hesitant began speaking freely. But the gains were fragile; ASR errors with proper nouns and Hindi loanwords, unfamiliar accents, hold-to-talk buttons that 35% of learners couldn't operate correctly. Small technical frictions quickly unraveled nascent confidence. The paper highlights a core design tension: students wanted open-ended, conversational practice, whereas administrators wanted curriculum-aligned assessment. Reconciling both is the path to sustainable adoption. Includes a deployment checklist for educational chatbots in resource-constrained multilingual communities. Full paper: lnkd.in/eQSZ82x8 Grateful to @PennGlobal funding and the collaboration with @csbcashoka @AshokaUniv that made this study possible!

LLMs match or surpass human-crafted messages across multiple domains, from marketing to reducing conspiracy beliefs. Yet, our research, led by @sehgal_neil, adds nuance: AI chatbots can boost short-term vaccination intent, but their edge over quality public health messaging for lasting change, when controlled for the amount of time spent, is unclear. Surprisingly, a single, tailored AI message proved as effective as a chatbot for colorectal cancer screening, showing simplicity can scale, especially in medical contexts. Key takeaways: 1. AI complements, not replaces, traditional public health tools. 2. Short, personalized AI messages can be highly effective. 3. For lasting impact, AI needs integration with proven strategies. 4. Continued research with strong controls and long-term follow-up is essential to assess AI’s true, durable impact on public health.

🚨New WP!🚨 Structured AI Dialogues Can Increase Happiness and Meaning in Life In a preregistered RCT, four psychology-grounded #AI chatbots improved well-being across several outcomes. Co-authors: @JonasP_Schoene @JEichstaedt @AadeshSalecha @slyubomirsky 🧵👇

We built chatbots to improve wellbeing, based on typical positive psychology interventions. They appear to be reasonably effective. If you like, you can try them!

Great venue for interdisciplinary LLM/NLP and mental health work. The special issue is in a reputable journal for mental health research. I'm excited to be a part!

Article I wrote for @psyche_the_mag about the value of descriptive work to scientifically understand intense and meaningful altered states of consciousness. In my view, Jamesian curiosity and empiricism is better suited to the topic than Jungian enthusiasm or Freudian cynicism.

It’s been a privilege to work with an amazing multidisciplinary team of co-authors on this project @sandracmatz @sal_giorgi @HAndySchwartz @MengesJochen. The paper is open access. Happy to see this one finally out in print! /fin psycnet.apa.org/fulltext/202…
