## Past Employment
**Postdoctoral researcher** with a focus on developing efficient artificial neural network based approaches for accurate, high dimensional excited state dynamics.
* **Sep 2023 – Present** European MCSA-Bienvenue postdoctoral fellow at the Institute of Physics Rennes (IPR), France
* **Spring 2023** collaborating visit at the IPR, Rennes, France
* **Year 2022** postdoctoral researcher in the Martínez group at Stanford University, CA, USA
* **Year 2021** postdoctoral reseacher in the Eisfeld group at the University of Bielefeld, Germany
* **Jan 2021** PhD under Wolfgang Eisfeld at the University of Bielefeld, Germany
## Research Interests
* **Photochemical processes in atmospheric and astrochemistry:** Particular focus on isolated molecules in the gas phase at finite temperature, with research experience in the modelling of photodetachment processes.
* **Numerical method development based on artificial neural networks:** Developed and refined schemes for the construction of diabatic potential energy surfaces using artificial neural networks. Particularly focused on preconditioning techniques to imbue models with physical information, reducing the strain of the network.
* **Efficient, modularized models of complex systems:** Continued efforts to provide schemes that allow for models to be extended to the full-dimensional problem by building upon restricted-dimensional models to mitigate innate problems of high-dimensional coordinate spaces (curse of dimensionality).
* **Molecular quantum dynamics of excited states:** Conducted in-depth theoretical studies of Jahn-Teller type systems and the impact of the geometric phase effect on their spectroscopy.
* **Mechanochemistry and photoswitches:** General interest in the development of high quantum yield photoswitches and molecular machines.
## Education
