Dr Usher-Smith worked on our Yorkshire Kidney Screening Trial.
Dr Cissy Yong
Dr Yong got her MBBS and intercalated BSc in Surgical Sciences from University College London in 2014. It was here she gained her first taste for hypothesis-driven science through investigating the role of toll-like receptors in critical limb ischaemia with the Vascular Research Unit, Royal Free Hospital, London. This galvanised her pursuit for integrating research with clinical training, leading her to obtain jobs as a General Surgery Academic Foundation Doctor and later as a Urology Academic Clinical Fellow.
During this time, in conjunction with UM co-lead Professor Grant Stewart and Dr Christian Frezza, she developed an interest in understanding how kidney cancer manipulates physiological metabolism to evolve and advance in a manner that surpasses current understanding and treatment options available to tackle this important disease process. As a urological trainee, Dr Yong became interested in bringing the bench closer to the bedside, closing in on some of the gaps in translational medicine, through the development of novel surgical models to study kidney cancer metabolism.
With support from the Fulbright-The Urology Foundation Scholarship award, Dr Yong spent three months in the world-renowned metabolomics lab of the DeBerardinis Group, UT Southwestern Medical Centre, Texas, learning the gold-standard techniques in conducting in vivo isotopic tracer studies in both human and patient-derived xenograft models for the evaluation of dynamic cancer metabolism. This invaluable experience laid the foundations for her Wellcome Trust PhD for Clinicians Training Fellowship, under the joint supervision of Grant Stewart and Christian Frezza. Capitalising on the breadth of patients with kidney cancer at Cambridge University Hospitals, one of the highest volume kidney cancer and oncology services in the UK, in conjunction with the Frezza lab, a world-leading cancer metabolomics lab, her overall aim is to develop the use of isotopic tracers to investigate in vivo dynamic metabolism in this broad cohort of surgical patients with kidney cancer, as well as develop novel synergistic translatable platforms through the concurrent use of human tissues.
Dr Yong is completing her PhD under the co-supervision of UM co-lead Professor Grant Stewart.
