Vahid Aref is a member of technical staff in IP and Optical Networks research lab within Nokia Bell Labs since 2015. He received his PhD degree in computer and communication sciences from École Polytechnique Fédérale de Lausanne (EPFL), Lausanne, Switzerland, in March 2014.
Prior joining Bell Labs, he was a research assistant in the communication theory laboratory (LTHC), EPFL, from 2010 until 2014. Then, 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. He has published more than 80 peer-reviewed conference proceedings and articles in prestigious journals such as Nature photonics, IEEE Transactions of Information Theory, IEEE Transactions on Communications and IEEE/OSA Journal of Lightwave Technology. Dr. Aref has received several awards for his works including the co-recipient of best journal award 2018 (ITG-Preis 2018) from German Society of Information technology (ITG).
Vahid's fields of research include coding and information theory, communications theory, machine learning and deep learning.
