Life and research

After graduating from high school, Lennart Ralfs began his university education at the University of Hamburg in autumn 2013. In his Bachelor's degree, he studied Industrial Engineering and Management, specialising in Operations & Supply Chain Management. In his bachelor's thesis, he developed a concept for improving the quality of order processing at a manufacturing company. After successfully completing his bachelor's degree, Mr. Ralfs continued his studies in the consecutive master's programme in industrial engineering in the field of production technology. He completed his studies as a Master of Science with his master's thesis, the development of an excellence and module concept for the automation of battery assembly. Parallel to his university education, he also gained practical experience in industry through internships in Germany and abroad. There he was responsible for projects to improve production and related logistics processes. Since June 2020, Mr. Ralfs has been working at the Chair of Production Technology and, as a PhD student in Technical Sciences at the University of Innsbruck, is focusing on possible application scenarios for exoskeletons in production systems.

Life and research

After graduating from high school, Oliver Ott completed his internship year in industry at the Interstate University of Applied Sciences NTB Buchs, Switzerland. During his internship year, he worked as a young professional for thyssenkrupp Presta AG, Eschen, Liechtenstein.

Mr. Ott completed his Bachelor's degree in Mechanical Engineering at the Technical University of Munich (TUM), Germany. As part of his Bachelor's thesis, he focussed on machine learning methods to support the wear prediction of worm gears. He also worked as an assistant scientist at the Research Centre for Gears and Transmission Engineering (FZG). There he developed and supervised a database application for the documentation of tests carried out.

Following his bachelor's degree, he continued his master's degree at the Technical University of Munich in general mechanical engineering, specialising in the fields of medical technology and assistance systems as well as mechatronics and robotics. As part of his term paper, he developed a decision algorithm for autonomous vehicles based on game theory approaches and flexible strategies. Mr. Ott completed his studies with his master's thesis, the design of a muscle-model-based control system for an active pneumatic ankle orthosis.

Since June 2021, Mr Ott has been working at the Chair of Production Technology and is investigating possible applications of context-specific optimisation of exoskeleton support as a doctoral student in technical sciences at the University of Innsbruck.
