Jörg Worlitschek is a full professor since 2014 at the Institute of Mechanical and Energy Engineering at Lucerne University of Applied Sciences and Arts, where he had accepted a lecturer position in 2012. Based on his educational background and his 9 year industrial experience at the analytical instrument company Mettler-Toledo in the fields of crystallization, calorimetry and software development, he started the research field Thermal Energy Storage at Lucerne University of Applied Sciences and Arts. This research lead to the Competence Center Thermal Energy Storage with today 33 researchers active in this field. While Jörg Worlitschek’s work focused from the beginning on the analysis of material properties and heat transfer in latent heat storage systems, his full professorship entailed broadening the spectrum of methods developed and applied. Additionally, Jörg Worlitschek has founded and is hosting the annual conference ‘Swiss Symposium Thermal Energy Storage’, which deals as a network for approximately 150 researchers from Switzerland and internationally.
