Short biography

Kai Kruber studied B.Sc. of Chemical Engineering from 2010 – 2015 and M.Sc. of Chemical Engineering from 2015 – 2016 at TU Dortmund University. From 2016 – 2020, he worked as a Ph.D. student at the Laboratory of Fluid Separations at TU Dortmund University. Since November 2020, he continues his Ph.D. studies at the Institute of Process Systems Engineering.

Field of research

In his research, Kai Kruber focusses on the development of efficient optimization-based methods supporting process synthesis and design. Especially, the optimization of solvent-based separation processes is part of his work.
