I am currently immersed in research focused on unraveling the intricacies of photoprotective mechanisms in green algae, with a particular interest in understanding how manipulating these mechanisms can enhance their tolerance to suboptimal environmental conditions. My work centers around the unique dynamics of the PSBS protein, which is exclusively constantly accumulated in land plants and plays a crucial role in the Non-photochemical quenching mechanism essential for photoprotection.

While the PSBS protein's function is well-established in land plants, its regulation and function in green algae remains to be elucidated. As part of the Photosystem II, the PSBS protein has gained significance as photosynthetic organisms transitioned to land-based environments. In my research, I utilize Chlamydomonas reinhardtii as a model system to explore the signals perceived by green algae and how they integrate these signals to prepare for and acclimate to high light stress.

This work contributes to a broader understanding of photoprotection in green algae and sheds light on the molecular mechanisms that drive their responses to environmental challenges. Through this research, I aim to contribute valuable insights to the scientific community and advance our understanding of the relationships between green algae and their environments.

The methods applied in this research include: transcriptional analysis (qRT-PCR), protein analysis (SDS-PAGE, Western blotting, chlorophyll fluorescence analysis (DUAL-PAM).
