Microorganisms have been proposed to play a role in shaping the Earth's climate by acting as ice nuclei (IN), which influences the formation of clouds. This can have significant implications for the global distribution of clouds and precipitation, and therefore for Earth’s weather patterns and climate. From an astrobiology perspective, exoplanets atmospheres have provided most of the available evidence for us to investigate the possible existence of life on that planet. Thus, atmospheric phenomena that may influence by ice nucleation active (INA) bacteria such as planetary albedo may serve as potential atmospheric biosignatures.

However, the process of mixed-phase clouds and global climate on Earth influenced by INA bacteria is not well understood. To increase our insight into the impact of biogenic IN in the atmosphere, My research project aims at characterizing molecular and physical properties of INP and at the possibility of quantifying INP, which influence the atmospheric process.
