Pratibha L. Gai FRS FRSC, FREng[1] is Professor and Chair of Electron Microscopy and Director at The York JEOL Nanocentre (Departments of Chemistry and Physics, University of York, United Kingdom)[2]
Originally from India, Prof Gai has a PhD in Physics (Cambridge University), Cavendish Laboratory)[3]
In 2009, after years of development, Gai, who holds a chair in electron microscopy and is co-director of the York JEOL Nanocentre at the University of York, succeeded in creating a microscope capable of perceiving chemical reactions at the atomic scale.[4] This is an advance on conventional microscopes at this scale, which can only view innate material in the “dead” conditions of a vacuum at room temperature. It is known as the atomic resolution environmental transmission electron microscope (ETEM)
With the help of colleagues, she built and refined the machine over two decades, beginning with a lower-resolution prototype when she was a postdoctoral researcher at the University of Oxford. She then spent 18 years in the US at chemical firm DuPont and the University of Delaware.[4]
