Dr Vahid AREF

Vahid AREF is a member of technical staff in IP and Optical Networks research lab, Nokia Bell Labs. Dr. Aref earned his B.Sc. and M.Sc. in electrical engineering from Sharif University of Technology, Iran, in 2006 and 2008. He received his PhD degree in computer and communication sciences from École Polytechnique Fédérale de Lausanne (EPFL), Lausanne, Switzerland, in March 2014.

Before Joining Bell Labs, he was a research assistant in the communication theory laboratory (LTHC), EPFL, from 2010 till 2014. In collaboration with Bell Labs, he conducted post-doctoral research in the institute of telecommunications (INÜ) at University of Stuttgart in 2014. Since 2016, Dr. Aref also serves as guest lecturer at the University of Stuttgart.

Vahid's fields of research include coding and information theory, optical communications and nonlinearity mitigation techniques.
