Dr. Mohammed is an Assistant Professor in the Division of Physical Sciences and Engineering. He is the principal investigator of ultrafast laser spectroscopy and four-dimensional electron imaging laboratory and he is affiliated with Solar and Photovoltaics Engineering Research Center at KAUST, and at present, his research activities are focused on the development of highly efficient solar cells with the aid of cutting-edge nanotechnology, laser spectroscopy, and ultrafast electron imaging. Prior to joining KAUST in December 2012, Dr. Mohammed was a senior research associate in Professor Ahmed Zewail’s group at Caltech, USA. While there, Dr. Mohammed joined the research group of Professor Zewail and worked on the development of new laser spectroscopic and time-resolved electron imaging techniques. Prior to his arrival in Pasadena, California, Dr. Mohammed spent more than a decade in Germany, Switzerland and Japan, embarking on the development of new laser spectroscopic techniques for direct observation of many chemical, physical and biological processes in real time. The accomplishments of Dr. Mohammed have resulted in more than 120 articles, invited talks and conference proceedings; and a large number of these papers are published in very high impact scientific journals including Science, Advanced Materials, Nano Letters, Advanced Energy Materials, Angewandte Chemie, PNAS, JACS, Chemical Communications, Advanced Functional Materials, Journal of Physical Chemistry Letters and Small.
