I am an associate professor in the Department of Computer Science at the University College London. I am also a member of Centre for Inverse Problems and Centre for Medical Image Computing.
Between 2010 and 2013, I held an EPSRC Postdoctoral Research Fellowship "Image Reconstruction: the Sparse Way" at UCL to investigate the implications of sparsity on image acquisition and reconstruction in different modalities. Before coming to UCL in the end of 2009, I was a PDRA in the School of Mathematics at the University of Manchester working on novel X-ray CT scanners for airport baggage screening.
My interest is in broad areas of Inverse Problems, Numerical Analysis, Scientific Computing and Machine Learning. In particular in numerical solution of inverse problems, tomographic image reconstruction, tailored PDE solvers for use in inverse iterations (PDE based forward problems), compressed sensing, sparsity and compression, applied harmonic analysis and machine learning. I enjoy working on mathematical problems which arise from real life applications. Presently, I am particularly interested in methods which rigorously combine numerical analysis with machine learning to leverage available data .
PhD opportunities: I am always looking for mathematically minded PhD students . I am a supervisor in FAI and i4Health CDTs, which provide competitive funding opportunities. Also sometimes have independently funded projects. Contact me to discuss up to date opportunities .
