I am a PhD student, eager to utilize my expertise in physics-based modelling, simulation, and control to contribute to achieving the UN climate goals. One promising area with great potential for saving energy and CO2 emissions is the building stock. Developing a framework to make model-based energy optimization of buildings applicable to a wide range of buildings based on as little data as possible is an important prerequisite for large-scale adoption and significant energy savings. This is the goal I am working towards in my dissertation.
