Dr. Thais Couasnon
Building A 71, Room 224 (Büro - Wissenschaftler/in)
14473 Potsdam

Function and Responsibilities:

Postdoctoral fellow in the group Interface Geochemistry (section 3.5)

Research Interests:

Thaïs Couasnon did her PhD at the Institut de Physique du Globe de Paris, on the biomineralization of manganese on the surface of bacterial biofilms. During her PhD, she collaborated with the Laboratoire Matériaux et Phénomènes Quantiques (MPQ) of the Université Paris Cité to image the biomineralization process in a liquid at the submicrometer scale and at high temporal resolution using liquid phase transmission electron microscopy. She is currently a postdoctoral fellow at the German Research Center for Geosciences (GFZ) to develop this relatively new technique to study the formation and transformation of minerals in situ, in order to better understand the mechanisms governing the mobility and bioavailability of elements in natural and industrial settings.

May 2023: Happy to share our latest contribution to the Journal of Physical Chemistry Letters: "Tailoring the Acidity of Liquid Media with Ionizing Radiation: Rethinking the Acid–Base Correlation beyond pH". This work sheds light on the concept of acidity during the interaction between ionizing radiation (electrons and photons) and liquid phases.
