Claudia MignaniAssistant / PhD candidate
In my ongoing doctoral studies, I research ice formation in clouds. Particularly, I am interested in understanding the relevance of ice-nucleating particles and ice multiplication in mixed-phase clouds and their effect on precipitation. My major research is based on field measurements and includes ice formation at moderate supercooling (i.e. at temperatures around -15 °C).
