Biography
Dr Araujo’s overarching career goal is to demonstrate the transformative power of mathematics in developing real insight and innovative solutions to fundamental problems in the Life Sciences. She has a special interest in cancer research, particularly cancer signal transduction and anticancer therapeutic strategies. Collectively, she has had over sixteen years of research experience within the field of theoretical biology, which has allowed her to develop both analytical and computational approaches to the elucidation of important problems in cell biology and medicine.
Dr Araujo’s recent mathematical work on cellular protein networks has changed our scientific understanding of the structure and function of cellular communication via molecular networks. Until recently, the sheer size and interconnectedness of these molecular networks has prevented us from being able to understand and predict likely network responses to pharmacological inhibition. This novel line of research is now pointing to the fundamental mathematical principles that govern how biological systems function at the molecular level, and is creating a new level of insight as to how new treatment strategies may be devised on an individualised/personalised basis.
