Quantum vibrational dynamics in proteins

Vibrational energy transport in proteins is important for a variety of nonequilibrium biological processes. In many situations, the standard classical description of vibrational transport leads to incorrect rates and pathways in comparison to the full quantum description. However, fully quantum calculations are not feasible for large atomistic
systems. The aim of this project is to develop the appropriate level of theory — a mixed quantum-classical theory — to accurately and efficiently describe vibrational energy flows in biomolecules. The project will involve modelling and interpreting recent experiments that have measured the flow of energy in peptides on the level of individual amino acids.

 
The successful candidate will be supervised by Dr. Johan Runeson, whose research is focused on developing mixed quantum-classical methods to simulate energy transfer in various contexts. The project will also involve collaboration with the Biomolecular Dynamics Group of Prof. Dr. Gerhard Stock. 

The project offers 4 years of funding (salary TV-L E13, 75 %) through the DFG research unit FOR5099: “Reducing complexity of nonequilibrium systems”. The starting date is flexible within early 2026. 
Interested applicants should send their CV, grades, and a description of why they are interested in this specific project. Solid knowledge of quantum mechanics and statistical mechanics is expected.
