🚨 New Paper Alert🚨 I’m very happy to announce that my job market paper is now official on【Management Science】! We propose a novel multitask learning & bandit algorithm built on robust statistics and Lasso, which shows notable performance both theoretically and practically.

Excited to see our paper "Generative AI Can Harm Learning" cited in Ch 7 of the 2025 Economic Report of the President: whitehouse.gov/cea/written-ma… Paper: papers.ssrn.com/sol3/papers.cf…, co-authored with Osbert Bastani Alp Sungu Haosen Ge, Ph.D. Ozge & Rei

Excited to once again co-organize the 4th Annual Workshop on AI & Analytics for Social Good at UMD on 5/2 with Margret Vilborg Bjarnadottir, Jessica Clarke, Jui Ramaprasad, and John Silberholz! Early-career scholars, please submit your "AI for good" work by 2/14: rhsmith.umd.edu/departments/de…

ICYMI: A study on how generative #AI can harm student learning, led by Hamsa Bastani, was featured in the 2025 Economic Report of the President. Learn how, without guardrails, GenAI can prevent students from developing valuable learning skills: knowledge.wharton.upenn.edu/article/withou…

Conformal prediction sets are a useful way to capture uncertainty for LLMs & deep learning models. But they're data-hungry! We propose a semi-bandit algo to learn these sets online. Check out our ICML Conference paper: arxiv.org/abs/2405.13268 Work led by Haosen Ge, Ph.D. & with Osbert Bastani

Super cool paper using brain imaging to track cognitive load while writing essays! As expected, people under-use their brain when using LLM assistance, but interestingly, they also struggle more when switching back to writing on their own -- AI assistance creates "cognitive debt"

Our work understanding the impact of GenAI on education is out in PNAS today! We confirm what many educators already suspected -- without appropriate guardrails, GenAI can harm student learning. We urgently need better safeguards to prevent these harms.

“I talked to a lot of kids, [and] I asked them why they’re using AI instead of putting in their own effort, and they just don’t believe they can do better because they have lost that sense of accomplishment,” said The Warren Center for Network & Data Sciences affiliate Hamsa Bastani. marketplace.org/story/2025/07/…

Longer thread incoming, but Richard H Thaler and I have a new book coming out “Winner’s Curse: Behavioral Economics Anomalies—Then and Now”, out on October 21. And our UK publisher is running a promo!

Interestingly, an economics paper that came out in 2023 predicting which jobs would overlap most with AI turned out to be right. A new Microsoft study of actual AI use by workers (more on that in another post) found a 90% correlation between real world overlap & the predictions.

I love this! Time & time again, you see companies waste valuable engineering/compute resources on complex systems w/o bothering to test simple ones (that often do just as well). PLUS adding complexity slows future innovation
