Since I have started my master thesis, I am a member of the AG Heberle. Meanwhile I became a PhD student which allows me to further focus on my master thesis topic. I predominantly perform time-resolved vibrational spectroscopy. I developed my interest for biophysics during a lecture, a friend of mine persuaded me to attend. It hadn't take long and this topic fascinated me.

Like most of us, I investigate membrane proteins, more precisely channelrhodopsins. Channelrhodopsins are membrane channels that open after light excitation and permit ions to pass through. In order to understand the gating mechanism on a molecular level I perform time-resolved FT-IR and UV/Vis spectroscopy. These techniques allow me to define and trace vibrational states in the protein. From this I draw conclusions about structural and functional properties of the protein.
