Martin Geier's research interest is the development, realization and application of mesoscopic numerical methods. The cumulant lattice Boltzmann method, developed by Martin Geier and his co-workers, has been successfully applied to transport problems at various length scales ranging from sub-mircon scale particle laden flow in micro electromechanical systems (MEMS) to the kilometer scale for the simulation of pollutants in urban environments.
In addition to his research on new mathematical models, in order to realize such versatile simulation tools, Martin Geier develops new algorithms and data structures for massively parallel computing on various hardware. His algorithms have been successfully implemented on General Purpose Graphics Processing Units (GPGPUs) as well as on many-core super computers.
Martin Geier obtained a diploma in micro microsystems engineering from the University of Freiburg and obtained his Ph.D. at the Laboratory of Simulation of the Institute of Microsystems Engineering (Imtek) of the same university. His Ph.D. thesis was honored with the Wolfgang-Gentner-Award. He did his Postdoc research as a fellow of the Japan Society for the Promotion of Science (JSPS) at the University of Kyoto. From 2009 to 2015 he was lecturer (Akademischer Rat) at the Institute for Computational Modelling in Civil Engineering (iRMB) at the TU Braunschweig. Since 2015 he holds the Junior-Professorship "Theory of kinetic methods" at the TU-Braunschweig.
Martin Geier was a visiting faculty member at the Indian Institute of Technology Madras. He also visited the University of Rome 3, the Changchun Institute of Optics, Fine Mechanics and Physics, and the City College of New York.
Martin Geier has been giving lectures at University level since 2008. His teaching experience includes lectures for diploma, bachelor, master and Ph.D. students of microsystems engineering, civil engineering, environmental engineering, computational science and engineering, and mechanical engineering. He gave several invited lectures at institutions in Germany, France, Italy, UK, Peoples Republic of China, Republic of China, India, Japan and USA.
