Biographical Sketch 

Dr. Ayman Sherif El-Said received his Ph.D. from Heidelberg University, Germany in 2004 after successful completion of research work in the field of ion-solid interaction at the GSI Helmholtz Centre for Heavy Ion Research (Darmstadt- Germany) during 2000 to 2004. Before joining GSI, Dr. El-Said completed his master’s degree in applied nuclear physics from Mansoura University, Egypt in 1998. In 2005, he was awarded the Lise Meitner Fellowship from the Austrian science Fund (FWF). This fellowship enabled him to conduct research work at the Vienna University of Technology, Austria from 2005 to 2007. As a senior scientist, he worked in the same University from 2008 to 2009 performing experiments in the same research area, namely nanostructuring using ion beam technology. From 2009 to 2010, Dr. El-Said worked as experienced researcher at the Institute of Ion beam Physics and Material Research of Helmholtz-Zentrum Dresden-Rossendorf (Dresden-Germany) by obtaining the Alexander von Humboldt fellowship for experienced researchers in 2009. He received the state incentive award in Physics from the Egyptian Academy of Science and Technology for the year 2010. Since May 2012 Dr. El-Said is a physics editor of the Arab Journal for Science and Engineering (Springer Verlag).
