My research deals with the development of new methodologies to generate and optimize technology chains for the manufacturing of safety-critical products.


Within industry projects, I consult companies on how new and existing products can be manufactured with greater efficiency and greater profitability.


As a lecturer, I teach about productivity and profitability in manufacturing and supervise students writing both Bachelor and Master theses.
