The Autonomous University of Madrid invites applications for a MSCA Postdoctoral Fellowship in Translational Cancer Research and Precision Oncology within the Chromosomal Instability and Therapy Response group. The project focuses on tumour evolution, cancer stem cell biology, therapeutic resistance, and preclinical models such as patient‑derived organoids and xenografts. Candidates will develop independent research aligned with chromosomal instability, multi‑omics biomarker discovery, inflammation‑driven gastric cancer, and innovative therapeutic strategies, benefitting from state‑of‑the‑art facilities and international collaborations.
