Arthur's research spans several key areas in modern machine learning, including:
- Kernel methods for causal effect estimation and two-sample testing
- Deep learning architectures for proxy causal learning with complex confounding
- Adaptive gradient flows for generative modeling
- Nonparametric statistical tests with theoretical guarantees
- Applications in distributional reinforcement learning and Bayesian inference
Recent publications demonstrate his focus on causal inference with hidden confounders (AISTATS 2025), deep learning adaptivity in instrumental variable regression (ICLR 2025), and novel approaches to two-sample testing with adaptive kernel selection (NeurIPS 2024). He has also contributed extensively to distributional reinforcement learning and hypothesis testing frameworks.
As an advisor, he supervises multiple PhD students including Jakub Wornbard, Zikai (Steve) Shen, and Zonghao (Hudson) Chen, while co-supervising others. His methodological contributions are implemented in various software packages available at the Gatsby Unit, including tools for kernel-based covariate shift correction, independence testing, and maximum mean discrepancy calculations.
