Therese Weißbach receives her PhD

Therese Weissbach during her PhD celebration

Therese Weißbach, a Physics student from the team Isotopologues has successfully defended her PhD entitled 'Spectroscopic isotopic ratio analysis on speleothem fluid inclusions - analytics and paleoclimatic case studies'. Congratulations for this great achievement and all our best wishes for her future.

Therese has developed and characterized a new instrument to measure stable water isotopes in fluid inclusions based on Cavity Ring-Down Spectroscopy (CRDS). Her analysis on several case studies, including speleothems from Europe and Puerto Rico, allowed to identify the slopes of deuterium and oxygen isotope fractionation and its deviation from the global meteoric water line. Her measures, thus provide clear evidence of evaporation effects, which are linked to natural climate change. Fortunately, we were able to celebrate her success, thanks to the nice weather and the necessary measures to insure the distance between us.
