Ahmad (Executive Editor) and Michael Way (Editor-in-Chief) We are delighted to announce the appointment of Guangshuo Ou as an Editor on Journal of Cell Science. Guangshuo obtained his PhD in cell and developmental biology from the University of California, Davis. His thesis work, conducted under the guidance of Dr Jon Scholey, focused on ciliogenesis in Caenorhabditis elegans neurons and elucidated how microtubule-based motor proteins are used to build neuronal cilia. Guangshuo received his postdoctoral training with Dr Ron Vale at the University of California, San Francisco, where he developed imaging techniques to study neuroblast migration and division in C. elegans larvae and discovered a new myosin-based mechanism underlying neuroblast asymmetric division. In 2011 he was recruited by the Chinese government with the Junior One Thousand Talent Plan Award as an investigator at the Institute of Biophysics Chinese Academy of Sciences. In 2013 his group relocated to the School of Life Sciences at Tsinghua University in Beijing, and he became a principal investigator of the Joint Center for Life Sciences at Tsinghua and Peking Universities. He continues to study neuroblast development using C. elegans as a model organism. Guangshuo has had a long-standing interest in understanding the molecular and cellular mechanisms of cell division and cell migration in developmental systems. Guangshuo has developed imaging methods to follow neuroblast development in a living nematode larva, and his laboratory devised the somatic CRISPR– Cas9 technique to generate conditional knockouts in order to dissect the underlying molecular regulation. His laboratory has obtained new information regarding signalling pathways that direct neuroblast migration in vivo. He continues to work on intraflagellar transport and introduces genome-editing tools to New Editor Guangshuo Ou. model human ciliary diseases. Guangshuo has received international awards, including the for Cell Biology and a Chinese National Outstanding Youth Newton Advanced Fellowship from the Royal Society, the Damon Scholarship. Runyon Cancer Research Foundation Postdoctoral Fellowship We are very pleased to welcome Guangshuo to Journal of Cell Award, the Norton B. Gilula Award from the American Society Science and look forward to working with him. Journal of Cell Science 303.
