lindner@...

I have an extensive background in metabolic engineering of prokaryotic organisms. I completed my diploma thesis on polyphosphate metabolism in the institute of biotechnology at the research center Jülich. During my PhD studies, at the institute of molecular microbiology and biotechnology at Münster University, I investigated and engineered the central metabolism of C. glutamicum. I then joined the institute of Genetics of Prokaryotes at Bielefeld University, where I continued my metabolic engineering work, with a special emphasis on alternative carbon sources, sugar transport, glycolysis, and the pentose phosphate pathway. I further engineered C. glutamicum for the production of various compounds of interest. Later, I joined Algenol Biofuels in Berlin, working in strain development of Cyanobacteria. At Arren’s group I design and implement synthetic pathways for formate assimilation in E. coli, using state of the art metabolic engineering and genome editing techniques.

Behrens@...
I gained my diploma in biochemistry at the University of Potsdam. During my studies I became interested in microbiology, and therefore I made my Diploma thesis in intestine microbiology, studying the effect of microorganisms on the formation and excretion of potential carcinogenic nutrients. After my Diploma, I worked for a while in a medicine products company. I completed my PhD studies in the field of geological microbiology, working at the Institute of Earth and Environmental Science at the University of Potsdam. There, I developed and constructed high-pressure, high temperature incubation systems for cultivation of extremophiles as well as for the extraction of organic compounds from condensed organic matter. At AG Bar-Even, I am responsible for maintaining and operating the technical equipment.

Aslan@...
I received my B.Sc. degree in biology at the University of Gaziantep (Turkey), studying molecular identification of pathogens of chick-pea. I completed my master's degree at Linköping University (Sweden), where I investigated the adaptation of landrace barley to day-length and frost-conditions, making use of 19th century barley collected at different locations in Europe. I have recently obtained my PhD in Molecular Biology from the Swedish Agricultural University in Uppsala. During my PhD studies, I demonstrated a novel strategy of utilizing intermediates of the de novo fatty acid biosynthesis pathway in vegetative tissue for the production of wax esters in tobacco plants. I further introduced a new metabolic pathway to reallocate carbon flux in the endosperm of rice plant. In Dr. Bar-Even's group, I engineer synthetic photorespiration pathways, using the model bacterium E. coli as a testbed, with the aim to implement the novel routes in photosynthetic organisms.

Cotton@...
I studied for my undergraduate degree at the University of Cambridge (Part II Biochemistry), writing a short thesis on the roles of alkanes in cyanobacteria. I continued my education at Imperial College London where I studied for a Masters of Research in Structural Biology, investigating both structural mechanisms of control in the Calvin cycle and modelling residence times of water in intrinsically disordered proteins. My PhD research was also at Imperial College, where I investigated replacing the Calvin cycle in a photosynthetic bacterium, Synechocystis sp. PCC 6803, with an alternative carbon fixation cycle. In Dr. Bar-Even’s group I work to expand possible formate assimilation pathways by investigating pathways reliant on the promiscuous activities of relevant enzymes.

aespinoza@...
My research interest lies on synthetic microbiology. In the past, I have developed a novel bacterium-plant system to investigate the molecular and physiological interactions between a microaerophilic N2-fixing bacterium and a mangrove plant. This was part of my MSc and PhD studies at Max Planck Institute for Marine Microbiology and Jacobs University in Bremen. Then, I joined the Federal Institute for Materials Research and Testing (BAM) as a postdoctoral researcher, where I optimized the bacterial strain Halomonas elongata to overproduce the metabolite ectoine. This was part of a cooperation project with the biotechnological company Bitop AG and BAM. Currently, I am working in Dr. Bar-Evens group to rewire the central carbon metabolism of Pseudomonas putida and standardize a synthetic biofluorination pathway.
