I am a freelance mathematician, photographer and explorer of all questions and assumptions. Welcome to my homepage. Please support the freedom of computing through the Free Software movement [FSF] and enjoy some of my photography.
I have expertise in partial differential equations, inverse problems and scattering theory. Most recently I have focused on three topics: the behaviour of waves near sharp corners or high-curvature points, backscattering, and the propagation of waves in networks. The latter concerns assessing the quality of water supply pipes remotely using pressure waves.
