Susanna “Susi” Quach

PhD student

Susi loves all things liver regeneration, and adapting this knowledge to translational approaches. She studied biology at TU Dresden for her bachelor degree. During and after her master studies at Universität Leipzig, Susanna trained and worked at the Max Delbrück Center for molecular medicine (MDC) in Berlin.

Julian Weihs

PhD student

Julian is from Berlin. He is very captivated by how our body cells do their job and how we could support or regenerate them when they lose their native function. He studied biology at the Humboldt University Berlin in his bachelor degree and molecular medicine at the Charité in his master program. When he is not pipetting liquids from one tube into another, he enjoys long walks and watching plays at the theater.

Natalia Martagón

lab manager

Natalia is the lab manager of the Rezvani lab. She holds a B.S./M. S. in Biomedical Research and Biochemistry from the National Autonomous University of Mexico. Natalia has worked in various Mexican and German research institutions, including the Max Planck Institute and University Hospital in Freiburg (Germany). Her work has ranged from yeast signal transduction to phagocytosis and developmental hematopoiesis. Natalia is always curious about immunology, evolutionary and regenerative biology.

Leonie Schumm
Clinician Scientist

Leonie is a Clinician Scientist who is a resident of pediatrics at Charité while focusing on biliary atresia in the lab. As child-loving physician, she is very motivated to contribute to improved treatment options and quality of life for children with rare diseases through her research work. If there is still time after the clinical and the lab work, Leonie enjoys to be out in nature and whenever she is on holidays she loves to travel the world.

Artemisia Sayed
Full-time MD-thesis student

Arte” is a full-time MD-thesis student at Charite University Medicine Berlin and a funded member of the Tight Junction (TJ)-TRAIN Graduate School in Berlin. In her project, she is looking for answers about the interplay of immune and epithelial cells in biliary atresia and leverages co-cultures involving intrahepatic cholangiocyte organoids for this purpose. She has always been interested in pediatric and rare diseases. Her personal dream for the future is to contribute to the identification of novel pharmacological treatments for biliary atresia. After her work in the lab, she enjoys playing the violin in an orchestra as well as turning her painting ideas into creative art.

Mijuna Claire Juliet Meindl

Molecular Medicine student

at Charité

Mijuna is enrolled at the Molecular Medicine Master’s program at the Charitè Berlin, having completed her B.Sc. in Biology at the Humboldt University in Berlin. Her interests span across various domains within molecular biology, with a particular fascination for stem cell research. Outside the lab, she enjoys her time with friends, watching movies and dancing.

Pia Dernick

master student

Humboldt University Berlin

Pia is currently pursuing a master’s degree in Quantitative Molecular Biology at Humboldt Universität. Her research project focuses on biliary atresia and she is interested in utilizing organoid modeling for regenerative medicine and studying infectious diseases. When she is not busy in the lab, Pia enjoys creating illustrations and exploring the green spaces around Berlin.

Milad “Milo” Rezvani
Group leader
Clinician Scientist

Milo is a proud father, Pediatrician, Pediatric Gastroenterologist-Hepatologist and Regenerative Liver Biologist who takes care of children and young adults with gastrointestinal and liver diseases. Since Medical School, when he cared for his first patients with devastating liver diseases, he is passionate about establishing regenerative therapies for end-stage liver diseases.

He trained as a Pediatrician at Boston Children’s Hospital/Harvard Medical School where he also pursued liver biology research at the Massachusetts General Hospital. He further completed a fellowship in Gastroenterology, Hepatology and Nutrition at Cincinnati Children’s Hospital Medical Center – an epicentre of Pediatric Liver Research.

As a scientist, he trained with Holger Willenbring (University of California San Francisco), Takanori Takebe (Cincinnati Children’s Hospital/Tokyo Medical and Dental University/Yokohama City University) and Wolfram Goessling (Massachusetts General Hospital/Harvard Medical School).
