I am a senior lecturer in Maths & Stats within the School of Engineering and Information Technology at Murdoch University (associated with both the Maths&Stats group and the physics group), a visiting fellow/campus visitor at both the Australian National University and a ‘Privatdozent‘ (associate lecturer) of the Friedrich-Alexander University of Erlangen-Nuremberg. I refer to my field of research as ‘Materials geometry’, that is, the materials science and physics of complex nano- or micro-structured materials addressed through the goggles of geometry, including hyperbolic, computational and stochastic geometry. A particular research focus are ordered network-like nanogeometries based on triply-periodic surfaces and nets, formed spontaneously by self-assembly or in biological systems, with a variety of interesting properties, from photonics to mechanics, and with a likely role in many biological processes. I enjoy interdisciplinary work, between mathematical modeling, physics, physical chemistry and materials science.
