Paris-Saclay, France
Research Scientist

Biography

Dr. Sara Ayoubi received her MSc in 2012 from the Lebanese American University, and her Ph.D. in 2016 from the Concordia Institute for Information and Systems Engineering, Montreal, Canada. Her Ph.D. thesis garnered her best dissertation award, and she was selected as Valedictorian for the joint faculties of Engineering, Computer Science, and Fine arts. In 2016, Dr. Ayoubi cofounded the Montreal Operations Research Student Chapter, which received the cum laude award for best Informs student chapter for two years in a row. In 2017, she joined the Cheriton School of Computer Science at the University of Waterloo as a postdoctoral fellow. In that same year, she was selected as a rising star in Electrical Engineering and Computer Science as part of the rising star program hosted by Stanford University for women in STEM. In 2018, she was a postdoctoral fellow at INRIA Paris Research Center. Since 2019, Dr. Ayoubi is a permanent research member of the Modeling & Optimization group at Nokia-Bell-Labs, Paris-Saclay, France. Her research interests are in the fields of Networks, Robotics, Operations Research, and Algorithm Design.
