Key Points

  • The organizers announced that Max Welling will host an AMA on Wednesday, April 15, from 17:00 to 18:30 CEST (11am–12:30pm EDT).
  • Max Welling is an ML researcher with experience across academia, big tech, and founding, and has recently focused on AI for physical and scientific systems, including work on Microsoft’s Aurora Earth modeling system.
  • He co-founded CuspAI, where the team is building a materials “search engine” aimed at navigating messy, high-dimensional design spaces to propose new materials with desired properties.
  • The AMA will cover topics such as ML for noisy/sparse/partially observable environments, AI4Science and “Physical AI,” foundation models vs domain-specific methods, and the hardest open problems around data quality, synthesizability, and deployment.
  • Discussion will also include human-in-the-loop approaches for reliability, plus Max Welling’s career advice centered on high-societal-impact problems like energy materials and carbon capture.

We're thrilled to announce that Max Welling will be joining us for an AMA on Wednesday April 15th from 17:00 to 18:30 CEST (11am - 12:30pm EDT)

Who is Max Welling?
Max Welling is an ML researcher whose career has spanned academia, big tech and life as a founder -- most recently working on ML for physical and scientific systems. Over the past few years he's moved from "classical" ML work like GNNs, Bayesian Deep Learning, CNNs) into AI for science and materials, including time on Microsoft's earth modelling system Aurora.

He is also the co-founder of CuspAI, where they're currently building a "search engine" for next generation materials. In practice, their work focuses both on building AI systems that are able to search extremely messy, high-dimensional spaces and propose new materials with specific properties, and dealing with the gaps arising between models/data, and the real world.

He will host an AMA at the time specified above, and will be delighted to discuss the intersection of AI and Materials Science with us.

Here is a selection of topics he'd like to go deep on:

  • ML Architectures that work in noisy, sparse, and only partially observable environments
  • Science not just as a "use case" for AI, but as a fundamental layer of the infrastructure
  • AI4Science in general, focusing on cases like Foundation Models vs domain-specific approaches (what works, what's hype, what's real?
  • "Physical AI" as in treating experiments and lab loops as part of the computation, not just downstream validation. (Like treatign the physical world as a live data-generator for frontier model training
  • The hardest unsolved problems at the interface of ML & Science (Data quality, synthesizability, deployment)
  • Human-in-the-loop systems and how to ensure model output reliability
  • ML Career advice (Why he focused his work on problems with the potential for big societal impacts like carbon capture, energy materials & compute efficiency)

His main aim will be to connect with the community & to share some of his knowledge and expertise.

His most impactful contributions include, among others:

Semi-Supervised Classification with Graph Convolutional Networks
Auto-Encoding Variational Bayes
Bayesian Learning via Stochastic Gradient Langevin Dynamics
Equivariant Diffusion for Molecule Generation in 3D
Aurora: A Foundation Model for the Earth System
