PhD Position in Developmental Biology: Fibroblasts in Organ Development

10. 9. 2023

The Sumbalová Koledová laboratory at the Institute of Molecular Genetics (IMG) – BIOCEV Centre, Prague, CZ, is looking for a passionate, intellectually curious doctoral candidate with an interest in developmental biology.

The PhD project will tackle the role of fibroblasts during mammary gland development. The doctoral candidate will analyze genetic mouse models (functional models, lineage tracing) and perform advanced organoid cultures, scRNA sequencing and spatial transcriptomics analyses (among other techniques).
