Areas of expertise:

I’m a research scientist in GTK’s geothermal energy team. I’ve specialized in underground energy storage research (aquifer, borehole and cavern thermal energy storage and underground hydrogen storage). I have experience in numerical heat transfer modelling and utilizing distributed temperature sensing data to compare experimental data to modelling results.
