Rebecca's research is predominantly divided into two themes. First of all, she works on tumour blood flow and therapy predictions. Her group are developing new models using sophisticated mathematical averaging methods and closely integrating them with high resolution in vivo and ex vivo imaging data to ensure they are parameterised and tested, and can be used as a tool to better understand and interrogate cancer therapies. This involved a close collaboration with Dr Simon Walker-Samuel from the UCL Centre for Advanced Biomedical Engineering; together, they have established the research group SCALES (Simulating Cancer Across Length SCALES), which brings together a team of mathematicians, medical imagers and cancer biologists in this area. In 2016, Rebecca and Simon were awarded the Rosetrees Trust Interdisciplinary Prize 2016 for research at the interface of maths/ computer science and medicine, for their project on Barriers to Successful CAR T-Cell Therapy in Pancreatic Cancer.

Secondly, Rebecca conducts both mathematical modelling and experimental studies to characterise the link between cellular environment and tissue function in tissue-engineering. Through collaboration with Dr James Phillips (UCL Biomaterials & Tissue Engineering), we are combining mathematical modelling, in vitro and in vivo experiments to design and test engineered constructs for peripheral nerve repair. In 2016, Rebecca was awarded an EPSRC grant on New Mathematical Models to Direct the Design of Peripheral Nerve Repair Conduits.
