Nicole Engert, PhD

​Nicole is a microbiologist with an interest in host-pathogen interaction. She is investigating infection mechanisms of Clostridioides difficile and Human Norovirus. To this end, she develops a human stem cell-based intestinal model to study novel vaccines and correlates of protection.

research interests:

iPSC, IBD, stem cell biology, human intestinal organoids


Maria Warschinke

Maria studies Biochemistry and is currently doing her Master in our group. She is developing a platform for culturing human intestinal organoids.

Aina Kehinde ("Kenny") Oluwasegun, MSc.

​Kenny is PhD student and holds BSc. in Microbiology and MSc. in Medical Microbiology and Parasitology. He is Early Stage Researcher in the Innovative Training Network EUROoC and develops an hiPSC based liver-on-chip model. His works focuses on metabolic pattern of liver zonation and disease mechanisms of nonalcoholic steatohepatitis.

​research interests:
hiPSC, hepatocyte biology, NASH

Mohamed Ismail Abdelwahab Hassan, PhD

Mohamed is a microbiologist working as PostDoc on generating isogenic stem cell-based liver models to study the effect of microbial metabolites in the context of immune-modulatory therapies and infections 

research interests:

short chain fatty acids, liver-on-chip, host-pathogen-interaction, macrophage biology, S. aureus


Valentin Wegner, B.Sc.

Valentin is PhD student and holds a BSc. in Molecular Medicine. He works on the establishment of a stem cell based gut model for studying the impact of the human microbiota on immune modulatory therapies.
