Yeon-Kyun Shin is a Professor of Biophysics at Iowa State University, USA. His lab uses spin labelling electron paramagnetic resonance (EPR) and single molecule techniques to investigate the structure and the dynamics of SNARE complexes, to uncover fusion intermediates, and to observe the real-time dynamics of the fusion pore. Highlights are the discoveries of a SNARE four-helix bundle with EPR in 1998 and the hemifusion intermediate in intracellular membrane fusion in 2005. Prof Shin has been an Editorial Board Member for Scientific Reports since 2016.
