We represent you!

The Doctoral Representatives Council consists of two doctoral representatives from each department of the MNF and was built to enable and improve the exchange between all departments and their students.

You can contact us for ideas and suggestions regarding the Doctoral Representatives Council or everything related to your doctoral studies. We will collect your input and bring it to the attention of the different graduate school steering committees and/or offices. Vice versa we will bring information or requests to your attention. 

Concerning our interests, we elect delegates for different commitees like the Hochschulkonferenz, the student consilium, the Board of the Graduate Schools, the Promotionsausschuss and the Consilium AMNZ. 

Doctoral Representatives Council

Dennis Zeh - Main Representative

Dennis Zeh completed his Bachelor studies in chemistry at the Eberhard Karls University Tübingen, focusing on organic chemistry in the research field of carbohydrates and synthesis of oligosaccharide mimetics. During his Master studies in the United States at the University of Massachusetts Boston he then focused on analytical chemistry and biochemistry in the field of mass spectrometry, investigating toxin induced protein expression levels in HeLa cells and the influence of ion interference in MS2 and MS3 tandem mass tag experiments. Currently, Dennis is a PhD student in Prof. Schäfer’s group at the University of Cologne (Institute for Organic Chemistry), working on gas phase reaction mechanism elucidation and ion/molecule reactions in the gas phase.

Joss Pepe Strache - Deputy Representative

Joss Pepe Strache performed his cooperative Bachelor studies at the FH Aachen and Forschungszentrum Jülich. In his research work at the Institute of Bio-Organic Chemistry he concentrated on the enantioselective synthesis of dihydrofurans employing cinchona alkaloids. In his Master studies at the University of Cologne majoring in organic chemistry the focus was set on natural product synthesis and catalysis. Currently, Joss Pepe is a PhD student in the research group of Prof. Dr. H.-G. Schmalz (University of Cologne, Institute of Organic Chemistry). His research interests are target molecule synthesis as well as application of transition metal-catalyzed transformations.

Stephan Schlegel

Sarah Bachmann

Sarah Bachmann studied Biology at the University of Cologne. During her Master’s she focussed on biochemical and cellular functions of mitochondrial proteins. She moved on to neurobiology when she started her PhD in late 2018 in the lab of Hans Zempel at the Institute of Human Genetics. Her project focusses on the functional characterization of the microtubule-associate protein Tau and its brain-specific isoforms under physiological and neurodegenerative conditions.

Yana Staneva

Yana Staneva completed both her Bachelor and Master studies in Mathematics at the University of Glasgow, Scotland, UK. Currently she is doing her PhD studies in the research group of Prof. Dr. Markus Kunze at the Mathematical Institute in the University of Cologne. Yana is working on "Algebraic and analytic aspects of integrable systems", funded by CRC/TRR 191. Her interests lie mainly in the intersection of physics and mathematics, more precisely, dynamical and integrable systems.

Konstantin Weiss

Konstantin Weiss obtained his Bachelor’s degree in Biochemistry at the Goethe University Frankfurt/Main where he also completed his Master studies in Biochemistry. During his studies he spent half a year at the University of Toronto (Canada) investigating novel inhibitors for uncommon EGFR mutants in non-small cell lung cancer. His Master thesis was focussed on the recombinant expression and characterization of cyanobacterial tripartite efflux pumps. Currently, Konstantin is a PhD student in the group of Prof. Dr. Riemer (University of Cologne). In his project he investigates the regulation of DPP9 and its role in controlling dual protein localization between cytosol and mitochondrial IMS.

Leonardo Rydin

Leonardo Rydin finished his Bachelor in the University of Lisbon in Physics in 2013 and moved on to the University of Bonn to obtain his Master’s degree in Physics in 2017. His Master thesis revolved around the emergence of anomalous behaviour of coupled-oscillator-system dynamics contingent on the topology of coupled network structures, under the supervision of Prof. Dr. Lehnertz. Leonardo is currently doing his Ph.D. under the supervision of J.-Prof. Dr. Witthaut in the Institute for Theoretical Physics and the Research Centre Jülich, researching stability and operationality of modern-day electrical power-grid systems.

Lukas Baumanns

Lukas Baumanns completed his Master studies in Mathematics and German Education at the University of Duisburg-Essen and subsequently joined the University of Cologne in 2017 for his doctoral studies. At the Institute of Mathematics Education he studies the activity of Mathematical Problem Posing in the group of Prof. Benjamin Rott. He is particularly interested in the process of this activity as well as metacognitive behavior that favors the quality of it.

Laslo Hunhold

Laslo Hunhold obtained his Bachelor's and Master's degrees in Mathematics at the University of Cologne, focusing on Numerical Mathematics, High Performance Computing, Information Theory and Signal Analysis. He is currently part of Professor Angela Kunoth's working group ‚Numerical Mathematics and Scientific Computing‘ and researching and developing mathematical foundations for deep neural networks.
