## Research

I am a Newton International Fellow at the Department of Applied Mathematics and Theoretical Physics and a member of the Cambridge Image Analysis group. I am also a Fellow of Hughes Hall, University of Cambridge. I am interested in inverse problems, variational regularisation and imaging science. Broadly speaking, inverse problems deal with extracting information from indirectly measured data using models that describe the data acquisition and arise, for instance, in medical imaging, astronomy, microscopy and geoscience. I am interested in cases when mathematical models of real-world phenomena are either imprecise, computationally too expensive or not available at all and are only given through training data. I develop regularisation theory and algorithms in this context and use them in imaging applications.

## Teaching

I am teaching Inverse Problems together with Hanne Kekkonen in Michaelmas term 2019/2020.

I taught Inverse Problems in Imaging in Michaelmas term 2018/2019.
