Tristan van Leeuwen


Tristan van Leeuwen received his BSc. and MSc. in Computational Science from Utrecht University. He obtained his PhD. in geophysics at Delft University in 2010. After spending some time as a postdoctoral researcher at the University of British Columbia in Vancouver, Canada and the Centrum Wiskunde & Informatica in Amsterdam, the Netherlands, he returned to Utrecht University in 2014 as an assistant professor at the mathematical institute. His research interests include: inverse problems, computational imaging, tomography and numerical optimization.


My research interests include image reconstruction, regularisation techniques, PDE-constrained optimisation, numerical analysis and scientific computing.
