Research

I am involved in the Seaclear2.0 Project and affiliated with the relAI School.

Learning Optimal Control

Learning the swing-up task for the Cartpole system (Master Thesis: Tobias Wittmann)

My research focuses on enabling autonomous decision-making in cyber-physical systems to optimize their performance and behavior.

I am particularly interested in:

Modeling and System Identification via Linear Transfer Operators
Using Operator-Theoretic Approaches to transform non-convex control problems into convex formulations
Data-Driven Control using Kernel Methods
Risk Measures for decision-making under uncertainty

Seaclear2.0

First sea trials in Marseille (December 2024). The USV seen in this video is the Seacat2.0 from Subsea Tech (https://www.subsea-tech.com/)

In the Seaclear2.0 project, we are developing an autonomous robotic system for seafloor litter collection. Building on Seaclear1.0, we aim to scale up to handle larger and heavier debris using a smart underwater grapple.

My research focuses on controlling the grapple, including developing a propulsion system with position and attitude control for fully autonomous navigation. Additionally, I am working on hardware development to optimize the grasping mechanism for efficient debris retrieval.

Contact

Unfortunately, I am currently unable to offer any new thesis projects or take on additional students.

I am always looking for motivated students interested in my research.
If you are considering a thesis in this area, please feel free to email me. Let me know your planned start date, and attach your CV and grade transcript so we can find the right topic for you.
