About the Author

Pratibha L. Gai is a senior research associate at the Central Research and Development, Science and Engineering Laboratories, DuPont and an adj. professor at the University of Delaware, USA. After graduating with a PhD in physics from the University of Cambridge, England, she taught and conducted research, leading the surface reactions group at the University of Oxford, England. She was elected a fellow of Wolfson College, Oxford. Her research interests are theories and experimental aspects of electron diffraction, defects in solids, ceramics, superconductors, semiconductors, heterogeneous catalysis and chemical synthesis. She has published about 22 research papers and reviews and has given numerous invited lectures internationally. She has received several educational awards and joint grants for her key fundamental work on in-situ electron microscopy of heterogeneous catalysts, including by the Royal Society, UK and the American Chemical Society. She is a member and fellow of several professional scientific societies, Chartered Engineer of the Institute of Materials, UK and is on the editorial board of international scientific journals.
