@lawlessopt.bsky.social and I are excited to present our #AAAI2026 tutorial on “LLMs for Optimization: Modeling, Solving, and Validating with Generative AI.” When: Tuesday, Jan 20, 2026, 8:30am–12:30pm SGT Where: Garnet 216 (Singapore EXPO) (Connor’s intro slides are shown here.) CC @aaai.org

It's been an absolute pleasure working with Ellen, Madeleine, and their amazing PhD students for the past year on making optimization more accessible with generative AI! I am on the job market this year - check out my website (conlaw.github.io) for more details on what I've been up to.

Please keep an eye out for Connor Lawless (@lawlessopt.bsky.social) on the faculty job market! Connor is a Stanford Human-Centered AI Postdoc, co-hosted by myself and Madeleine Udell. His research combines ML, computational optimization, and HCI, with the goal of building human-centered AI systems.

In our final session for the day, we're focused on a hot topic: machine learning and mixed integer programming. Connor Lawless will start the session and tells us how to use LLMs for cold-start cutting plane separator configuration. doi.org/10.1007/978-...

There's been a lot of work using LLMs to formulate MILPs, but how do we know that the formulations are correct? Come chat with Haotian at poster W-515 to learn about our work on automatic equivalence checking for optimization models!

Excited to be chatting about our new paper "Understanding Fixed Predictions via Confined Regions" (joint work with @berkustun.bsky.social, Lily Weng, and Madeleine Udell) at #ICML2025! 🕐 Wed 16 Jul 4:30 p.m. PDT — 7 p.m. PDT 📍East Exhibition Hall A-B #E-1104 🔗 arxiv.org/abs/2502.16380

Understanding Fixed Predictions via Confined Regions

Machine learning models can assign fixed predictions that preclude individuals from changing their outcome. Existing approaches to audit fixed predictions do so on a pointwise basis, which requires ac...

For decades, the US government has painstakingly kept American science #1 globally—and every facet of American life has improved because of it. The internet? Flu shot? Ozempic? All grew out of federally-funded research. Now all that's being dismantled. 1/ www.technologyreview.com/2025/02/21/1...

The foundations of America’s prosperity are being dismantled

Have you developed and/or implemented an optimization model to solve a real-world use case? We want to hear from you! We're extending our study on workflows in optimization modelling for a couple last interviews: tinyurl.com/3ejdr7su

Yesterday, I gave a @gurobioptimization.bsky.social webinar where I explored how to make #AI and #ML both #transparent and #fair without compromising on #accuracy. The recording of the talk is at www.brighttalk.com/webcast/1918.... Happy to hear about your feedback!

On a (Short) Optimization Tour Through Transparent and Fair ML with Prof. Dolores Morales

There is a common consensus that state-of-the-art Artificial Intelligence (AI) and Machine Learning (ML) algorithms are powerful in terms of their accuracy, but they are also perceived as opaque not b...
