Information

Curriculum Vitae

Waldemar Krieger has studied Chemical Engineering at the TU Dortmund University since 2010. He completed his bachelor thesis with the topic ‘Modelling of the reaction kinetics of a solvent-free and enzyme-catalyzed esterification’ at the chair of biochemical process engineering followed by his master thesis ‘Investigation of the methane pyrolysis in a capillary reactor’ which has been performed at the chair of chemical process engineering. Since 2016 he works as a research associate at the chair of equipment design investigating coiled microstructured devices and implementing sensor technology.
