Research interests:

Dynamical simulations of physical phenomena are essential to obtain insight into brain function. Animal brains exhibit distinct dynamics at mulitple scales, from single ion channels to coherent electrical fields that are so large that they can be measured at the scalp. One of the challenges in performing computer simulations is the precise specification of the model. In neural network simulation, a variety of modeling approaches exist, each with its own set of weaknesses and strengths.

NESTML (https://github.com/nest/nestml/) is a domain-specific language and toolchain that aims to make the specification of dynamical models simple, while remaining powerfully expressive. Neuron models can be specified in an accessible syntax inspired by Python (https://www.python.org/), and differential equations can be entered directly into the language. The code generation concept allows us to generate the fastest code possible for each individual target platform (from embedded system to supercomputer) while retaining generality. I am extending the NESTML language to cover models of the synapse, and strive towards creating the best overall user experience when using NESTML in neuroscience modeling.
