Complex systems:
Are there general mechanisms behind the emergence of collective system properties ? How can the key parameters be identified that control the collective behavior in complex, non-linear systems ?

Biophysics:
How can individual and collective cell migration be modeled as a stimulus-response problem, in which the cells continuously react on their changing local micro-environment by adopting their migration behavior accordingly ?

Neurophysics:
How to (automatically) construct a course-grained description of neural networks ? How does (deep) learning work ? How does the statistics of neural connection weights change during network training ? How can the learning rate of neural networks be improved ? What is the structure of the ‘loss function landscape’ in neural networks ?

Statistical Methods:
How to analyze and model systems with time- and space-varying statistics ? How to detect and characterize higher-order, non-linear correlations in complex data ?

Machine Learning and AI:
How can machine learning be applied to scientific problems so that it actually helps to understand the investigated systems ? Can the ‘blind’, gradient-based optimization of model parameters be replaced by a more intelligent, human-like way of model improvement ?
