Jan Hermann

I'm a BIFOLD junior group leader at FU Berlin.

My work focuses on advancing quantum chemistry through tight integration of deep learning. I search for suitable entry points for machine learning in electronic structure theory and incorporate exact priors induced by the underlying physics into neural-network and training architectures. The goal is to push through the simulation scale–accuracy trade-off offered by traditional methods of quantum chemistry.
