Bio

Ahmed El Oualkadi was born in Al Hoceima, Morocco, in 1976. He received B.S. and M.S. degrees in physics and electronics from Abdelmalek Essaadi University, Tetuan, Morocco, in 1998 and 2000, respectively. He received Ph.D. degree in electronics from the University of Poitiers, France, in 2004.
From 1998 to 2001, he was a research assistant in the Electronics & Microwaves Laboratory, Tetuan, Morocco. During this period, he worked in numerical modeling methods (TLM & FDTD) in computational electromagnetic and computer-aided design of microwave circuits.
From 2001 to 2003, he was a research assistant in the Laboratoire d’Automatique et d’Informatique Industrielle – Ecole Supérieure d’Ingénieurs de Poitiers, Electronics & Electrostatics Research Unit, University of Poitiers, France. In 2004, he was an assistant professor at University Institute of Technology, Angoulême, France. During this period, he worked, in collaboration with EADS-TELECOM, on various European projects (CORMORAN & MULTIMODULES) which concern the nonlinear analysis & RF circuit design of switched-capacitor filters for radio-communication systems.
In 2005, he was a research associate in the Université Catholique de Louvain, Microelectronics Laboratory, Louvain-la-Neuve, Belgium, where he worked on the design of low power high temperature circuits and systems, in SOI technology, for wireless communication especially for ZigBee (PHY IEEE 802.14.5) applications. During this period, he managed several European and regional projects (EUREKA, A 109 Witness, MEDEA+, CROTALE…) in the areas of wireless communication and sensor networking.
Currently, he is an assistant professor in the Ecole Nationale des Sciences Appliquées, Tangier, Morocco. His main research interest is the analog, mixed-signal and RFIC design for wireless communication and embedded system applications. Since 2003, he is an active IEEE member associated to the Circuits & Systems Society where he is a reviewer of IEEE journal of circuits and systems and ISCAS conferences. He is author/co-author of more than 30 publications and communications in recognized journals and international IEEE conferences.
