🚨New paper 🚨Human uplift studies -- RCTs measuring how AI changes human performance -- inform how we govern, deploy, and understand AI systems and their societal impacts.

My latest piece in Noema on the hidden costs of agentic AI: humans recruited to sense the physical world on an agent's behalf, potentially without their consent. We're all sensors. Link below.

We introduce epiplexity, a new measure of information that provides a foundation for how to select, generate, or transform data for learning systems. We have been working on this for almost 2 years, and I cannot contain my excitement! 1/7

LMArena office is buzzing today. The environment is superlinear. We are constructively interfering, always pushing one another to learn and exceed what we thought were our limits. The #1 trait that we look for when hiring is "Excellence." Producing work every day that meets the highest technical bar in terms of craftsmanship, performance, and reliability. There are other factors too, but never compromise on excellence. As a consequence, everyone on our team is a deep expert. This is required to build quality evaluations with confidence. Excellence begets excellence. Nobody wants to work in an environment with a bunch of wet blankets -- it kills the momentum. We're constantly raising the bar, and this is what leads to the feeling of energy. It's rare. If you're interested in working in this kind of environment, send me a DM. We're always looking for people that can raise the bar one notch higher.

Hi All! W/ @friederrrr + colleagues, we're studying how people do/don't use AI for formal mathematics. If you're a practicing mathematician, maths student, or otherwise do formal maths, please consider responding to this brief survey for our research! forms.gle/Dv9JbvUvpLeV8r…

🌱 Our first CHIA PhD cohort already brings together students from AI, social sciences, and public policy. cc: @Gates_Cambridge @ELLISforEurope @Grad_School_Hub @_phdpositions @DeepIndaba @wimlds @researchersjobs @_LXAI @ai_cam_mission @LeverhulmeCFI @trustworthy_ml

📅 Key dates: - Application deadline: Dec 2, 2025 - Gates Cambridge (US applicants): Oct 15, 2025 👩‍🏫 Supervisor expertise spans ML, NLP, robotics, HCI, ethics, and health, with faculty from across @Cambridge_Uni.

🎓 We're recruiting our second cohort of PhD students at the Centre for Human-Inspired Artificial Intelligence @Cambridge_Uni! Let's combine human + machine intelligence to create AI that advances social and global progress🚀 chia.cam.ac.uk/education/phd

Might be of interest @dsa_org @dsn_ai_network @trustworthy_ml @tejuafonja @JamesAllingham @smhall97 @lanfrica @TrustAI_Indaba

We’re hosting a @DeepIndaba workshop: Human-AI Interaction for the Global Majority 🤝🏾 Come join us in Kigali this August — details on how to submit can be found below! We’ll be joined by @krvarshney of @IBMResearch and Anicia Peters of @NCRST_Namibia 🙌🏾 #DLI2025 #Indaba2025

📢 New Preprint: What happens at a population level when humans learn from AI systems that themselves learned from us? We extended the classic "Rogers' Paradox" to explore human-AI learning networks—and found some surprising results! 🤖🧠 (Paper link in 🧵)

I’m excited to share new work from Datadog AI Research! We just released Toto, a new SOTA (by a wide margin!) time series foundation model, and BOOM, the largest benchmark of observability metrics. Both are available under the Apache 2.0 license. 🧵

@atalwalkar Thanks so much for your support and mentorship!!!

Congrats @umangsbhatt !

I'm grateful to @adrian_weller @stephenjcave @atalwalkar @andrewgwils @lawrennd @Mateja_Jamnik and many others for their guidance. I'll miss @NYUDataScience but look forward to new colleagues in @gilliantett @MyfanwyHill @JamieVicary @annalkorhonen @pokristensson @DrJennyG.

I'll be based at the newly formed @Cambridge_ITH and @CHIA_Cambridge. If you're interested in trustworthy AI, human-AI collaboration, or safety evaluations, feel free to reach out! I’m recruiting PhD students and postdocs soon. More details on my lab coming shortly. 🚀

📣 Life update: I'm joining the University of Cambridge this fall as an Assistant Professor and as a Fellow in Computer Science at @Kings_College. Excited to (re)join the @Cambridge_Uni community!

CDS Faculty Fellow Umang Bhatt (@umangsbhatt), CDS visiting researcher Valerie Chen (@valeriechen_), & colleagues developed MODISTE, a system that personalizes when AI should assist you—learning your preferences from your behavior. Presented at AAAI 2025. nyudatascience.medium.com/ai-isnt-always…

@johnpdickerson @MozillaAI @mozilla Congrats, John! Excited to see what you and the @MozillaAI team build :)

🚀 Career news: I'm now CEO at @MozillaAI and joining executive leadership @Mozilla! 🦖 Mozilla has always stood for a better Internet -- open, trustworthy, and people-first. With @MozillaAI, we’re bringing that mission to AI. 1/

I’m in Philadelphia this weekend at #AAAI2025 🔔 If you’re around, come by and chat with @valeriechen_ and me today (and tomorrow) about personalizing access to AI assistance! arxiv.org/abs/2304.06701
