Group Leader

Dr. Marianne Grognot
Junior Professor for Biophysics of Host-Microbe Interactions (Assistant Professor with tenure track)


Marianne studied biomedical engineering at the University of Technology of Compiègne (UTC, France). In 2016 she obtained her PhD in Physics from Ecole Polytechnique (France), working on a novel terahertz imaging technique in the Laboratory for Optics and Bioscience. She then completed a postdoc in the Taute Lab at the Rowland Institute at Harvard University (USA), where she used a high-throughput bacterial 3D tracking method and developed a new multiscale chemotaxis assay to explore bacterial navigation strategies. After a temporary position as a researcher and teaching assistant in the Laboratory of Biophysics and Evolution at ESPCI-Paris PSL (France), she started her own group at the Institute of Medical Microbiology in the RWTH University Hospital (Aachen, Germany).

Technician Assistant

Eva Leluc

After completing her Medical Technical Laboratory Assistant (MTLA) education at University Hospital in Düsseldorf, Eva worked in diagnostic microbiology in Aachen and Cologne for a total of 13 years. During these years she worked in different diagnostic departments, was assigned as a laboratory supervisor and produced microbiological demonstration materials for the microbiology practical course for students of human medicine. In 2020, Eva started her work in research in the laboratory of the Clinic for Geriatrics at Uniklinik RWTH Aachen and gained experience in cell culture with human primary cells. Eva has then joined our group in January 2023.

PhD student

M. Sc. Maria Dimitra Chiotelli

Maria Dimitra studied Mechanical Engineering at the University of Thessaly (Greece). Her Diploma thesis in Experimental Biomechanics has been awarded in the FEMS competition 2021.  During the last year of her undergraduate studies, Maria Dimitra pursued an ERASMUS+ research internship at Friedrich-Alexander-Universität (Germany). She then completed an MSc in Biomechanics and Biophysics Engineering at École Polytechnique (France), as a scholar from the French Government and the Greek State Scholarship's Foundation. and has been an intern at LVTS lab of Université de Paris during this period. In November 2022, Maria started her PhD thesis in Biophysics in our group. The thesis topic is focused towards the quantification of motility and chemotaxis of gut commensals.

PhD student

M. Sc. Marwan Malik

Marwan Malik completed his bachelor’s degree from St. Xavier’s College Mumbai in Microbiology and Biochemistry. During his second year, he interned for a year in the Institute of Chemical Technology Mumbai. After completing his undergraduate studies, he worked as a lab assistant in the department of Electrical Engineering in IIT Bombay for 6 months, working on the biological applications of voltammeters and spectrophotometers. He completed his master’s from LMU Munich in Molecular and Cellular Biology with a thesis titled “Determinants of chemotactic growth expansion”. Marwan joined us in October 2023, to work on the 3D tracking of bacteria swimming in mucus.”
