Professor Heather Harrington

Research Fellow in the Sciences & Mathematics


I obtained my PhD in 2010 from Imperial College London, and was a postdoc in Theoretical Systems Biology group (2010-2013). In 2013, I joined the Mathematical Institute at the University of Oxford. I teach
Part C Networks, ASO Mathematical Biology.

Research Interests

My research focuses on the problem of reconciling models and data by extracting information about the structure of models and the shape of data. To develop these methods, we combine techniques from a variety of disciplines such as computational algebraic geometry and computational topology, statistics, optimization, network theory, and systems biology.

Keywords: Mathematical modelling, nonlinear algebra and computational topology for applications to data science, systems biology and medicine

I always enjoyed mathematics, but also was curious about medicine. I learned that it is possible to combine mathematics to study biology and medicine in university, and continued these directions, specifically reconciling mathematical models and data. If we can understand how biology works at the genetic/molecular/cellular scale, as well as what goes wrong in disease, then we may be able to use mathematics to help design drug therapies.
