The Sustainable Engineering and Management group uses knowledge from engineering and business disciplines to build on several topics which include resource management, sustainable product development, material and energy management and circular economies. Our understanding of these subjects allow us to develop new business models in areas like electromobility and environmental management.
Central our research and teaching is system and networked thinking. Here, various methods and instruments are applied, which range from risk, criticality, and efficiency analysis, material flow balances, design for recycling, life cycle assessments, system-dynamic simulation, to scenario technology. At the same time, the SEM group works in cooperation with other universities and companies on (research) projects to facilitate knowledge transfer between partners, the Rosenheim University of Applied Sciences and its students.
„Our motivation is to improve the sustainability of products and processes along with developing new models that contribute to more sustainable businesses.“Prof. Dr.-Ing. Sandra Krommes

Katja Zier

Dr., Dipl.-Chem.
Research Assisstant

Katja Zier has been working as a research assistant in research and development at the Rosenheim University of Technology since March 2020. She is currently researching the economic efficiency analysis and life cycle assessment of production processes in the field of circular economy. The use of recyclates for product manufacture motivates them to work in the field of Sustainable Engineering and Management (SEM).

Katja Zier studied chemistry at the Technical University of Dresden and received her PhD in 2014 in the field of inorganic materials and electrochemistry. She carried out the development of new types of energy storage materials at the Leibniz Institute for Solid State and Materials Research Dresden. From September 2015, she worked as a postdoc in the field of non-destructive material testing on the further development of ultrasound and noise emission test methods, before leading the working group on non-destructive testing at the TU Munich from July 2018 to March 2020.
