# Bethan Psaila

Bethan Psaila is a physician-scientist known for work in hematopoiesis, megakaryocyte/platelet biology and myeloproliferative neoplasms (MPNs). She is an Associate Professor of Hematology at the University of Oxford, a Cancer Research UK funded Senior Fellow, and a Senior Fellow of New College. In 2021, she co-founded Alethiomics, a drug-discovery company.

## Education

Psaila received her undergraduate and medical training at Clare College, Cambridge and University College London Hospitals. She went on to pursue a PhD at Imperial College London and Weill-Cornell University Medical School in New York, where she studied the role of megakaryocytes in cancer metastasis. She completed her specialty training in hematology at the Hammersmith Hospital as an NIHR Academic Clinical Lecturer at Imperial College London. Psaila was granted a prestigious Wellcome Clinical Career Development Fellowship, which supported further postdoctoral research in David Bodine's laboratory at the National Human Genome Research Institute in Maryland and with Professors Adam Mead and Irene Roberts at the MRC Weatherall Institute of Molecular Medicine, University of Oxford. She then obtained a Cancer Research UK Advanced Clinician Scientist to establish her own laboratory in the MRC WIMM in August 2019.

## Research

Dr. Psaila is an Associate Professor of Hematology at the University of Oxford and serves as a Group Leader at the MRC Weatherall Institute of Molecular Medicine and Associate Member of the Oxford Ludwig Institute for Cancer Research. Her research focuses on the tumor microenvironment in blood cancers:
* Interactions in normal and malignant hematopoiesis – Investigating the interactions between blood stem cells, megakaryocytes, and the stroma in both normal and malignant hematopoiesis.
* Bone Marrow Organoids – Development and application of human bone marrow organoids to study hematopoiesis and validate therapeutic targets in the relevant tissue microenvironment.
* Selective targeting – Developing novel strategies to selectively target disease-driving cancer stem cells and pathological megakaryocytes in myelofibrosis, a severe bone marrow malignancy.
* Platelet biology and early detection – Exploring the utility of platelet-associated DNA fragments in cancer detection and pre-natal diagnosis.

## Honors and awards

In 2015, Psaila was awarded a Wellcome Career Development Fellowship to use single cell techniques to study molecular mechanisms of abnormal megkaryocyte development in myelofibrosis
In 2017, Psaila won a prestigious Fellowship at the L’Oréal-UNESCO UK and Ireland For Women In Science
In 2019, Psaila received a Cancer Research UK Advanced Clinician Scientist Fellowship.
In 2021, Psaila received the RDM-WIMM Sir Andrew McMichael Award for Excellent Supervision and Mentorship, recognizing her exceptional mentorship and support of trainees.
In 2024, Psaila was awarded a Senior Fellowship funded by Cancer Research UK in partnership with the Rosetrees Trust. This fellowship supports her research into the progression of cancers from indolent to advanced stages and the development of new therapies.
