Research Overview
My research lies at the intersection of reinforcement learning, control theory, and AI safety. I focus on developing theoretically grounded algorithms for sequential decision-making problems with complex objectives, particularly in safety-critical applications.
šÆ Submodular Reinforcement Learning
Bridging submodular optimization with RL to handle non-additive reward structures that arise in real-world applications like experiment design and informative path planning.
š”ļø Safe Multi-Agent Learning
Developing provably safe algorithms for multi-agent systems with applications in coverage control, autonomous racing, and distributed robotics.
š Competitive Policy Optimization
Novel approaches to multi-agent reinforcement learning through competitive optimization, with applications in autonomous racing and game-theoretic scenarios.
š¤ Model Predictive Control
Integrating learning with control theory for safe autonomous systems, focusing on Gaussian processes and Bayesian optimization for uncertainty quantification.
Current Projects
š¬ Submodular Reinforcement Learning
Collaborators: Mojmir Mutny, Melanie Zeilinger, Andreas Krause
We investigate reinforcement learning problems where the reward function exhibits submodular structure. While these problems are NP-hard to approximate, we develop practical algorithms with conditional approximation guarantees. Applications include:
- Experiment design for scientific discovery
- Informative path planning for environmental monitoring
- Molecular design with diversity constraints
Status: Under review at top-tier venue

Research Philosophy
šÆ Theory-Practice Bridge
I believe in developing algorithms that are both theoretically principled and practically implementable. Every theoretical contribution should have clear practical implications.
š”ļø Safety First
Safety is not an afterthought but a fundamental design principle. I focus on provable safety guarantees for autonomous systems operating in uncertain environments.
š Interdisciplinary Approach
Complex real-world problems require interdisciplinary solutions. I draw from control theory, optimization, machine learning, and robotics to tackle challenging problems.
