I have studied photosyntesis, more specifically the dynamics of the proteins and protein complexes in thylakoid membrane. My PhD thesis focused on the assembly of the Photosytem II protein complex in higher plants. After the PhD degree, I have studied regulation of electron transfer routes and cyclic electron transfer as well as several auxiliary proteins and chaperones, such as the DNAJ proteins, which are involved in regulation of photosynthesis. I have also expertise on the acclimation of the photosynthetic machinery to the fluctuating light conditions. Methodologically, I have specialized in analyzing the dynamics of the thylakoid membrane protein complexes by using native gel electrophoresis.
