Dr. Shigeki Watanabe is trained in genetics, molecular biology and cell biology in C. elegans and mice with a special focus on imaging neuronal functions. He developed two novel techniques in electron microscopy that allow the visualization of proteins and membrane dynamics at synapses. One technique induces membrane movement using the optogenetic stimulation of neurons and captures the subsequent events at a millisecond temporal resolution using a rapid high-pressure freezing method. Another technique pinpoints the locations of proteins within their subcellular context by coupling super-resolution imaging with electron microscopy. Using these techniques, Dr. Watanabe is studying cellular and molecular mechanisms underlying synaptic transmission and synaptic plasticity.
He has collaborated with many scientists across the world and worked with various model organisms, including zebrafish.
