Simon Raffel runs an independent Emmy Noether research group at Heidelberg University Hospital studying the metabolic biology of leukemia stem cells (LSCs), building on earlier work (recognised with the 2017 Walter Schulz Prize) on amino acid breakdown in leukemia stem cells. He remains affiliated with HI-STEM and the Heidelberg-based LeukoSyStem consortium.
In 2026 his lab identified the TCA-cycle enzyme IDH3 as a selective regulator of AML leukemic stem cell maintenance: knocking down IDH3A raises intracellular citrate, activates AMPK and suppresses mTORC1, and sensitises resistant AML cells to the BCL2 inhibitor venetoclax.
