Mi-Sun Jang earned her Master's degree in Molecular Life Science from the University of Hamburg, where she investigated a potential gene therapy approach for a congenital paediatric disorder. She completed her PhD in Molecular Medicine at Hannover Medical School (MHH) in June 2025. Her doctoral research focused on dissecting the ontogeny of iPSC-derived macrophages, combining single-cell RNA sequencing (scRNA-seq) analysis with spectral flow cytometry to characterise developmental trajectories and cellular identities. Throughout her academic training, Mi-Sun has contributed to multiple peer-reviewed publications and has instructed students in key laboratory techniques, including PCR, cell culture, and flow cytometry.

Main research interests: Hematopoietic development, macrophages, tissue plasticity

Theresa Nägler studied Medicine at the University of Jena, with international stays in Italy, Austria, and England. She completed her doctoral thesis in the field of Hematology, focusing on the microenvironment and epigenetics in Multiple Myeloma, under the supervision of Annamaria Brioli. During her medical studies, she also enrolled in the Master's program in Molecular Medicine, where she is investigating DNA-protein interactions under the supervision of Tino Schenk. Theresa is currently a Clinician Scientist at the TITUS Research Fellowship at MHH. She joined the Lachmann Lab in April 2025, where her current research project involves the in vitro induction of alveolar macrophages for use in cell-based therapies and in vitro modeling.

Main interests: iPSC technology, alveolar macrophages, in vitro modeling

Utku Cem Yılmaz completed his Master's in Molecular Biology and Genetics at Middle East Technical University (METU), where he investigated transcriptomic regulation and RNA isoform diversity in hormone-responsive breast cancer. During this time, he was actively involved in several molecular oncology research projects supported by TÜBİTAK and the European Cooperation in Science and Technology (COST) program. In 2024, he joined the Molecular Medicine PhD program at Hannover Medical School (MHH) under the supervision of Prof. Dr. Nico Lachmann. His current research focuses on engineering iPSC-derived macrophages with regenerative and immunomodulatory potential for lung tissue repair. His broader interests include cell-based immunotherapy, synthetic biology, and translational gene editing approaches.
