°ÅÀÖ¶ÌÊÓƵ

Beth Psaila is a Cancer Research UK Advanced Clinician Scientist at the MRC Weatherall Institute of Molecular Medicine and Honorary Consultant in Haematology. She studied medicine at Clare College, Cambridge and University College London Hospitals. Following general medical training/MRCP she undertook a PhD in the role of megakaryocytes in cancer metastasis. This was a collaborative project between Imperial College London and Weill-Cornell University Medical School, New York. She then returned to the UK for her speciality training in Haematology at the Hammersmith Hospital as an NIHR Academic Clinical Lecturer at Imperial. After completing her clinical training, she secured a prestigious Wellcome Career Development Fellowship, which supported her postdoctoral research at the National Human Genome Research Institute, National Institutes of Health, USA and then the MRC Weatherall Institute of Molecular Medicine, University of Oxford, where she has been based since 2017. 

She has received many prestigious awards and fellowships in recognition of her work, including a L'Oreal-UNESCO Women in Science Award (2017). She is passionate about encouraging clinicians in training to pursue a joint academic-clinical career path. She now spends 80% of her time in translational research and 20% in the clinic, and hugely enjoys being able to combine scientific research with clinical practice and the opportunities this offers to engage patients with research and also to focus her research on clinically meaningful goals. 

Beth is a Senior Fellow in Clinical Medicine at °ÅÀÖ¶ÌÊÓƵ, and an Associate Professor in Haematology. 

Research Details

Beth leads a research group focused on the role of megakaryocytes (megs) in cancer. Megs are bone marrow cells that produce our circulating blood platelets and regulate the blood cell factory in the bone marrow. Normally one of the largest but rarest cells in the bone marrow, megs are completely unique in the human body because of their massive cell size and many copies of nuclear DNA. Her groups uses state-of-the-art techniques to study the genes and proteins in many thousands of blood stem cells individually, to work out how megs are produced from bone marrow stem cells, how they function in healthy people, and how this goes wrong in a group of blood cancers called myeloproliferative neoplasms. Her work has led to numerous publications in high-impact journals, with >4000 citations.
