European Workshop on Reinforcement Learning

October 2026

19th European Workshop on Reinforcement Learning (EWRL 2026)

Description

The European Workshop on Reinforcement Learning (EWRL) is the gathering hub of the Reinforcement Learning research community in Europe and one of the main world-class events in RL. We plan to make the 2026 edition an exciting event for researchers worldwide, both for the presentation of top quality papers, but also as a forum for ample discussion of open problems and future research directions.

Past editions of EWRL can be found here.

Topics

Reinforcement learning is an active field of research which deals with the problem of sequential decision making in unknown (and often) stochastic and/or partially observable environments. Recently there has been a wealth of impressive empirical results, including those coupling Deep Learning function approximators with Reinforcement Learning algorithms, as well as significant theoretical advances. Both types of advances are of major importance and we aim to create a forum to discuss such interesting results, their applications, consequences, and research perspectives.

We encourage submissions in both theoretical and practical aspects of Reinforcement Learning.

Venue

EWRL 19 will be located in the University of Lille, France.

Keynote Speakers

Nathan Grinsztajn
Mistral.
Nathan Grinsztajn works on agents at Mistral AI. Previously, he was a Member of Technical Staff at Cohere, where he worked on RL for LLMs and reasoning, and before that a research scientist at InstaDeep, where he focused on transformers for combinatorial optimization and discrete problems.
Anders Jonsson
Universitat Pompeu Fabra.
Anders Jonsson is a full professor in the Department of Engineering, where he heads the Artificial Intelligence and Machine Learning research group. His research interests involve sequential decision problems in which one or several agents have to make repeated decisions about what to do, mainly in the form of automated planning and reinforcement learning.
Sao Mai Nguyen
Ensta-Paris.
Sao Mai Nguyen is an associate professor at Ensta-Paris. She is interested in robotics, artificial intelligence and cognitive science. She tries to bridge these 3 aspects in her work, and started working in cognitive developmental robotics. She has a special interest in linking research of machine learning, robotic embodiment, child development psychology and neuroscience.
Alexandre Proutiere
KTH, Royal Institute of Technology.
Alexandre Proutiere is a professor at the Decision and Control Systems division in the EECS school at KTH, Royal Institute of Technology. His research interests are Machine Learning and AI, reinforcement learning, unsupervised learning, statistics, stochastic processes, control; applications to communication and social networks, cybersecurity.
Giorgia Ramponi
University of Zurich.
Giorgia is an Assistant Professor with Tenure Track at the Faculty of Business, Economics, and Informatics at the University of Zurich. She is also an affiliated professor at the ETH AI Center and an affiliated professor at the Data Science and AI, Computer Science, and Engineering department at Chalmers University of Technology.
Aviv Tamar
Technion ECE.
Aviv Tamar is an associate professor at Technion ECE, where he heads the Robot Learning Lab. His research focuses on AI and machine learning, with an emphasis on robotics applications. His long term goal is to bring robots into human-centered domains such as homes and hospitals.
Ambuj Tewari
University of Michigan, Ann Arbor.
Ambuj Tewari's primary area of research is artificial intelligence (AI) with a focus on machine learning (ML). His research group focuses on rigorous theoretical analysis of AI and ML models and algorithms. They also work on challenging real-world applications especially in chemistry and psychiatry.
