Malte Wittje successfully completes his doctoral examination

We are proud to have accompanied our colleague Malte Wittje on his academic journey: on November 25, 2025, he successfully completed his doctoral examination. We were happy to support him on this path, which once again demonstrates how valuable mutual growth can be.

“Practice-oriented design methodology for screw heat exchangers under efficiency and sustainability aspects” is the title of his dissertation. In it, Malte Wittje develops a practical approach to designing screw heat exchangers that are even more efficient and resource-saving in the future—a topic of great relevance for modern industrial applications.

Research meets practice

Malte Wittje’s academic career is closely linked to AMF-Bruns: in 2014, he began his dual studies at the company, which he completed in 2018. This was immediately followed by his master’s degree, which he successfully completed in 2020. Initial discussions and agreements regarding a doctorate began immediately after he completed his master’s degree. He officially began his doctorate in 2022 at the University of Paderborn in cooperation with PHWT Diepholz, accompanied by lectures at the University of Paderborn in 2022 and 2023. After submitting his dissertation in June 2025, he has now successfully passed his examination.
