Biography

Research in the Cvetkovska Lab is centered on photosynthetic organisms. We currently work with green algae and we study how they respond and adapt to stress. Our favourite models is Chlamydomonas sp. UWO241, an unusual green alga that originates from the depths of the permanently ice-covered lake Bonney in Antarctica and is adapted to a host of extreme conditions (low temperatures, high salinity, extreme shading). We use a combination of molecular and computational biology to investigate how genes and proteins evolve and function in extreme environments, and how Antarctic algae respond to stress. Plants and green algae share many conserved cellular mechanisms, and we will use the insights from algae to devise strategies for improving stress tolerance in land plants.
