From 1996 until 2017, he was full Professor for Industrial Chemistry at TU Dortmund University/Germany. In his research group renewable resources, in particular oleo compounds, terpenes and sugars, were important substrates. He is the author or co-author of a total of ten books dealing with industrial chemistry, catalysis and the chemistry of carbon dioxide. Dr. Thomas Seidensticker, was born in Marl, Germany, and studied chemistry at TU Dortmund University/Germany. He received his doctoral degree with distinction in 2016 under the supervision of Prof. Dr. Arno Behr. Since 2017, he is a junior research group leader in the group with Prof. Dr. Dieter Vogt in the Laboratories of Industrial Chemistry at TU Dortmund University. His research is dedicated to sustainable process design for homogeneous catalysts, including the development of innovative recycling methods and the conversion of renewable resources. For several years he has been a lecturer and trainer for lectures on renewable resources and has also written several review articles on this topic.
