BIOGRAPHY

Sebastian Rehfeldt Ph.D., born 1978 in Munich, studied Mechanical Engineering with specialization in Process Engineering at the Technical University of Munich (TUM) and received his doctorate (Dr.-Ing.) in 2009. Since then he has been head of the “Gas-Liquid Contact Apparatus” working group at the Institute of Plant and Process Technology at TUM. There, he is a lecturer for Heat and Mass Transfer, Equipment Design and Process Design. Since 2021 he is lecturer for “Instrumentation” in Chemical Engineering at TUM-Asia in Singapore.
