Ali has been working on the characterization of materials in the atomic and sub-atomic scale by advanced (scanning) transmission electron microscopy, (S)TEM. He joined the University of Oxford in Feb 2020 as a Postdoctoral Research Associate in Quantitative (S)TEM and Phasing Methods. He is working with Prof. Angus I Kirkland and Prof. Peter D Nellist. Ali is carrying out research in the development of advanced (S)TEM quantification and phasing methods within the framework of a large European project (ESTEEM3). He will also support the experimental programs of external users in the David Cockayne Centre for Electron Microscopy (DCCEM) and the National electron Physical Sciences Imaging Centre (ePSIC) who have been awarded instrument time through transnational access.

Prior to joining Oxford, Ali was working with Prof. Ian M Reaney as a Research Associate in Advanced Transmission Electron Microscopy of Tunable Materials and Devices at the University of Sheffield, UK. Ali completed his PhD in Physics under supervision of Prof. Richard Beanland at the University of Warwick, UK. Prior to his PhD studies, he also completed his B.Sc. and M.Sc. degrees both in Materials Science and Engineering in Iran at Isfahan University of Technology and K.N. Toosi University of Technology, respectively.

 

Research interests: Atomic resolution (S)TEM/EELS/EDS, quantitative STEM, Ptychography, defects and interfaces.
