Background

Dr. Shigeki Watanabe is an assistant professor of cell biology and of neuroscience at the Johns Hopkins University School of Medicine. His research focuses on cellular and molecular characterizations of rapid changes during synaptic plasticity.

Dr. Watanabe received his undergraduate degree and Ph.D. in biology from the University of Utah. He completed postdoctoral work in neuroscience at the University of Utah and Charité –Universitätzmedizin, Berlin. He joined the Johns Hopkins faculty in 2016.

He is a member of the Society for Neuroscience, the American Society for Cell Biology and the Biophysical Society. His work has been recognized with several awards, including the Eppendorf and Science Prize for Neurobiology from the American Association for the Advancement of Science.

Research Summary

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.

Lab

Work in the Shigeki Watanabe Lab is focused on cellular and molecular characterizations of rapid changes during synaptic plasticity. Little is known about either how the morphology of spines is regulated or how the surface occupancy of receptors is regulated. What are the morphological changes that trigger synaptic plasticity? How are receptors redistributed during this process? What are the molecular pathways that mediate the redistribution? Researchers aim to answer these questions using cutting-edge electron microscopy techniques in combination with molecular and biochemical approaches.
