Leona Schmidt-Speicher received her M.Sc. degree in mechanical engineering in November 2019 from the Karlsruhe Institute of Technology (KIT). During her degrees, she studied and worked at the University of Purdue (USA), wrote her bachelor thesis and worked at Global Advanced Manufacturing Institute (GAMI, China) and studied at the University of Córdoba (Argentina). She specialized in Medical Engineering and Microstructure Technology. After completing her studies, she joined the group “BioMEMS – Biomedizinische Mikrotechnik” of Prof. Dr. A. E. Guber at the Institute of Microstructure Technology (IMT) in the research field of biomedical microtechnology in December 2019. During her Ph.D., she will be working on the development of a modular microfluidic bioreactor for plant cell cultivation within the Dialog-ProTec-Project.
