2026 Scientific Award Winners

Constanze Bonifer

2026 Donald Metcalf Award

Recipient: Ellen Rothenberg, PhD

The receipient of the 2026 Donald Metcalf Award is Professor Ellen Rothenberg for her pioneering contributions to decoding the regulatory logic that drives multipotent cells toward a lymphoid cell fate.  While much of the early history of the experimental hematology field focused on the extrinsic factors that stimulate cell growth - paralleling the legacy of Don Metcalf himself - Dr. Rothenberg’s work has provided the essential "internal" counterpart for T cell development. She has spent her career answering a fundamental question in hematology: How does a multipotent progenitor translate a collection of external signals into a single, largely irreversible, developmental choice down the lymphoid path?

Dr. Ulrich Steidl

2026 McCulloch & Till Award

Recipient: Eirini Papapetrou, MD, PhD

Dr. Eirini Papapetrou of the Icahn School of Medicine at Mount Sinai has been selected as this year’s recipient of the McCulloch and Till Award. Dr. Papapetrou is being recognized for her innovative and high impact achievements in leveraging induced pluripotent stem cells (iPSCs) to model and study the mechanisms of myelodysplasia (MDS) and acute myeloid leukemia (AML).

Adam Wilkinson

2026 Janet Rowley Award

Recipient: Beth Psaila, MD, PhD

This year’s Janet Rowley Award is presented to Dr. Bethan Psaila for her ground-breaking and truly original work, covering myeloproliferative neoplasms, the microenvironment and megakaryocyte/platelet biology - research from discovery all the way to applications in clinical trials and commercialisation.
