In 2005 Volodymyr Shvadchak graduated from Kyiv National University (Ukraine) holding a diploma in organic chemistry and started PhD studies in Strasbourg University (France) in biophysical lab of Yves Mely. His work was focused on development of environment-sensitive fluorescent labels and application of them in monitoring protein interactions. He defined his PhD in 2009 and started to work as a postdoc in the group of Tom Jovin in Max Planck Institute for Biophysical Chemistry (Göttingen, Germany) studying the membrane binding of α-synuclein. He joined the Nanobiophysics group in September 2012 as a postdoctoral fellow and continue studies of α-synuclein membrane interactions focusing on the properties of protein oligomers.

TOPIC : Interaction of α-Synuclein oligomers with membranes

α-synuclein is an intrinsically disorderd protein that is deposited in form of amyloid fibrils in brain during Parkinson Disease. This protein can form oligomers and disrupt integrity of cellular membranes. I am studying the structure of α-synuclein oligomers in solution and in membrane bound form using fluorescence of environment-sensitive labels in order to understand the mechanism of α-synuclein-induced membrane leakage and to check the pore formation hypothesis.

I am also interested in the determination of the conformation of monomeric α-synuclein on membrane and in monitoring of the α-synuclein oligomerization on membrane using 2D FCS technique.
