My main research focus lies between power systems and physics-centric data analysis. I focus on how physics can help us improve our understanding of renewable energies, power-grid stability, energy markets, and microgrids. How can network sciences, dynamical and stochastic processes, and generally complex systems aid us in living in a more sustainable world?
In my research, I try to aim for a balance of applied physics and data sciences. The topics that interest me are power-grid stability, electricity price dynamics, and the impact of renewable energy on the former. I am also involved in projects working with paleo-climate and psychopathology data analysis.
