Autonomous E-Scooters

E-Scooter sharing systems are widely used for convenient short distance travels. These sharing systems however face several problems, like bad spatial coverage, need for juicers (people charging the scooters) and high maintenance costs. By developing scooters with autonomous driving and navigational capabilities we aim to overcome these challenges.

 

Analysis and control of heterogenous cell populations

Multiple aberrations in various cellular signaling pathways accumulate in the development of cancer. Many dysregulations occur in cellular pathways, that are activated in response to stress related stimuli such as DNA damage, nutrient starvation or death receptor ligands. Activity in these cellular signaling pathways causes cell fate decisions towards cell cycle arrest, senescence, autophagy or apoptosis. The signaling pathways furthermore affect each other and this interaction represents cell intrinsic control mechanisms.Together with our collaborators  we aim at a deeper understanding of these cellular control mechanisms.
We follow this aim by an integrative approach, where we combine methods from data analysis, biological system modeling and system theory.
The focus of our data analysis, in particular single cell and population data from fluorescence microscopy or FACS experiments, is to identify subpopulations (e.g. drug sensitive or resistant) within the biological sample which behave differently in response to some treatment (e.g. drug sensitive or resistant). The data from different subpopulations is then analyzed with the help of mathematical models that describe the process. The model classes that we use for this purpose ranges from classical ordinary differential equation (ODE) to partial differential equations (PDE) and stochastic differential equations (SDE) models.
The comparison of the model parameters, structure and predictions, that we get from the various subpopulations, allows us to identify crucial processes that cause the emergence of subpopulations. The knowledge that we ultimately obtain from this work flow helps to identify new drug targets, and to optimize treatment strategies. KK_Fig3
