Principal Investigator

Dr. Jana de Wiljes

I am the head of the research group and have been a PI of the Collaborative Research Centre 1294 on Data Assimilation since 2017 (currently PI on 4 projects for second funding period 2021-2025). Furthermore, I lead the educational robotics lab at University Potsdam and the organizer of the Golm Coder Dojo.

I mainly am interested in the development of computational methods and the derivation of mathematical principles for sequential learning particularly in the context of Bayesian inverse problems/nonlinear filtering.

Phd students

Katherine Briceno Guerrero

I am currently doing my PhD within Project B08 of SFB 1294 on Continuous learning by integrating reinforcement learning and data assimilation to individualise drug treatments. Within that project my research is mainly focused on designing new methodologies for decision support by combine sequential learning ideas with reinforcement learning tools and to derive the associate uncertainties. I am also the PhD representative of the International Research Training Group.

Marina Garcia Penaranda

I am a PhD student at GFZ (German Research Centre for Geosciences) working on the Collaborative Research Centre 1294 on Data Assimilation project B06: Novel methods for the 3D reconstruction of the dynamic evolution of the Van Allen belts using multiple satellite measurements.

I study the Earth’s Ring Current (1-100 keV), which is a is a complex dynamic system that plays an important role in geomagnetic storms. This ring-shaped current environment changes its structure and intensity on different time scales as a result from the incoming solar wind. Since particle populations display very different behaviors, is extremely hard to develop physics-based forecasting models. To tackle this issue, I am working on intercalibrating satellite data to improve the temporal and spatial resolution, which will be combined through data-assimilation techniques with physics-based models in order to get a better understanding of the underlying dynamical processes.

Postdoctoral researchers

Gottfried Hastermann

I am a researcher in the Collaborative Research Centre 1294 on Data Assimilation and interested in the quest of incorporating
inaccurate, and incomplete data into physics based models. 

To this end, I design algorithms and provide numerical analysis in the
interplay of Bayesian non-linear filtering and structure-preserving
methods for non-linear (partial) differential equations.

The models of choice often expose phenomena on multiple scales and
originate from Hamiltonian mechanics, geophysical fluid dynamics or
space weather prediction.  

Along the way, I develop research software in python and C++.

Dr. Karen Seidel

I am interested in machine and human learning of mathematics and computer science.
My current main research interest lies in statistical algorithmic learning theory, in particular the analysis of bandit algorithms with dependencies. I am also very interested in its connections to applied machine learning, cognitive science and robotics. I am jointly in the lab of Jana de Wiljes and Alexandra Carpentier.
