Dr. rer. nat. Josephine Thomas

Josephine is the leader of the junior research group GAIN.

She is a trained physicist and gained her doctorate with a thesis on non-linear dimension reduction applied to a topic of complex network theory.

She choose to work on Machine Learning and specifically on GNNs because she likes to do basic reseach but also see it go to a useful application quickly and because graphs are just cool: they can describe the formation of the universe as well as the internet, what more can a scientist want?

Her focus in GAIN next to supervising PhD students is the explainability of GNN algorithms.



Areas of Interest:

Graphs, deep learning, network geometry, quantum physics, renewable energies.

M.Sc. Silvia Beddar-Wiesing

Silvia is working towards her Ph.D. in the GAIN group with Dr. Josephine Thomas and Prof. Dr. Bernhard Sick as her supervisors.

She graduated with a B.Sc. in Mathematics and a M.Sc. in Computer Science with a specialization in Computational Intelligence and Data Analytics at the University of Kassel.

Her research topic addresses smooth embeddings of structural-dynamic graphs using Neural Networks. The focus is on embeddings that transform graphs with changing nodes and edges over time, i.e., including additions and deletions of nodes and edges. In particular, the goal is to obtain a model that processes structural-dynamic graphs of different time granularity and that represents them smoothly in a latent space.



Areas of Interest:

Pattern Recognition, Machine Learning, Graph Theory, Combinatorial Optimization, Time Series Analysis, Data/Information/Knowledge Fusion.

M.Sc. Alice Moallemy-Oureh

I am Alice and I am currently in the first year of my doctorate in the GAIN Group. Prior, I graduated with a M.Sc. in Mathematics and its applications to Computer Science from the university of Kassel. My specialisation in Mathematics lies in Algorithmic Commutative Computer Algebra and Geometry. In Computer Science, I focused in Logic and Data Analytics.

I am particularly interested in developing Graph Neural Networks, which are designed to master the handling of attribute dynamic graphs in continuous time representation. The first thing I would like to focus on is the so-called node embedding of such graphs, as this can be used to keep almost unlimited application possibilities open. The plan is to create more efficient wind power forecasts with the help of such a model.

In general, I am a very open, honest, and enthusiastic person who likes to meet new people and is up for any discussion - so don't be afraid to chat me up.



Areas of Interest:

Geometric Deep Learning, Machine Learning, Pattern Recognition, Commutative Computeralgebra, Geometry, IT-security.

M.Sc. Clara Holzhüter

I have joined the GAIN group in 2022 after I graduated with B.Sc. and M.Sc. in Computer Science at the University of Göttingen. During my studies, I specialized in Computational Neuroscience, especially in Deep Learning and Computer Vision.

The research area of my Ph.D. in the GAIN group is the application of GNNs in the power grid. Due to the inherent graph structure of electricity networks, GNNs are promising methods with regard to representation learning and information extraction for different use cases. My goal is to develop GNNs which enhance the efficiency and safety of electric networks by directly making use of their topology. For this purpose, I aim to combine Reinforcement Learning with GNNs to learn to control the power grid with regard to its topology. The field of graphs which change their topology or attributes over time is of particular interest for me, since power grids are highly dynamic systems.

As a Ph.D. student at the Fraunhofer IEE my research also addresses the application of such methods to real world problems, particularly in the field of renewable energies.



Areas of Interest:

Graph Neural Networks, Deep Learning, Computer Vision, Machine Learning, Graph Theory, Computational Neuroscience, Renewable Energies
