Biography/ Background

Amir Ebrahimi received the B.Sc. in electrical and electronic engineering from the University of Mazandaran, Babol, Iran, in 2008 and the M.Sc. in electronic engineering with fist class honours from Babol University of Technology, Babol, Iran, in 2011. From 2009 to 2012, he was a research assistant in Integrated Circuits Research Laboratory (ICRL), Babol University of Technology. In 2012, he was awarded an International Postgraduate Scholarship (IPRS) and the Australian Postgraduate Award (APA) to pursue PhD under Dr. S. Al-Sarawi, Dr. W. Withayachumnankul and Prof. Derek Abbott, in the School of Electrical and Electronic Engineering, The University of Adelaide. In 2016 he completed the PhD with Dean’s commendation for doctoral thesis excellence with a thesis entitled “Metamaterial-Inspired Structures for Microwave and Terahertz Applications”.  He was a visiting research fellow at Nanyang Technological University (NTU), Singapore during 2014–2015 hosted by Prof. Zhongxiang Shen. During his candidature, Dr Ebrahimi received several nationally and internationally competitive scholarships and awards.
