Brief

Dr. Sameh Ibrahim received the B.Sc. and M.Sc. degrees in electrical engineering from Ain Shams University, Cairo, Egypt, in 2001 and 2005, respectively. He received the Ph.D. degree in electrical engineering from the University of California, Los Angeles, in 2009. His Ph.D.'s thesis was entitled "High-Speed Low-Power Equalizers for High-Loss Channels". In the summer of 2006, he joined Texas Instruments, Dallas, TX where he worked with the high-speed serial links R&D group. In the summer of 2007, he joined Mindspeed Technologies, Newport Beach, CA where he worked with the signal integrity group. From January 2010 to April 2011, he was with Marvell Semiconductor Inc., Santa Clara, CA, where he worked as a Senior Analog Design Engineer in the high-speed serial-links group. He contributed to the design of many high-speed multi-standard serial-link transceivers.
In May 2011, he became an Assistant Professor in the electronics and electrical communications engineering department of Ain Shams University, Cairo, Egypt. He was also appointed as the unit head of the Communication Systems Engineering program at Ain Shams credit hour engineering program from 2011 to 2015. In July 2016, Dr. Ibrahim became an Associate Professor in the department.
Dr. Ibrahim joined the Integrated Circuits Laboratory of Ain Shams University in May 2011 where he started his research group. Current research in the group includes: High-speed serial links design with emphasis on low power and high performance, Bio-medical applications, and Integrated power management systems including switching and linear regulators and energy harvesting..
