- Scientific software development with C++, Python and Julia, see also my homepage for more on this
- Deep neural nets
I started releasing codes for research and teaching on my github page.
I am an applied mathematician working in the field of scientific computing. My current main objective is the simulation and design of numerical models and software for application processes that involve a wide range of relevant scales. Problems I am aiming to solve mostly come from geosciences but also comprise applications in computer science, engineering, physics or other fields of science. This involves in particular experience with models based on differential equations and numerical methods such as finite elements (FEM) as well as data driven algorithms, optimization and their large scale implementation using mostly C++ and other tools from software development. On this path I am involved in training and supervision of BSc/MSc/PhD students and scientific outreach activities.
It is my goal to bring scientific innovations further into real world applications. Recently, I also got interested in the application of neural nets to improve simulations and in agile project management which I see as a huge step into the right direction to trigger authentic creative potential in teams.
