Qian Hu

Biography

Qian Hu received the Ph.D. degree in electrical and electronic engineering from the University of Melbourne, Melbourne, Australia, working on different aspects of fiber-optic communication techniques, including few-mode fiber-based coherent optical fiber transmission and short-reach optical interconnects with direct detection. In 2015 she joined IP/Optical Networks department at Nokia Bell Labs, Stuttgart, Germany, where she is involved in the research on advanced digital signal processing for high-capacity optical transmission systems. Her current research interests include advanced modulation formats, high-speed transceivers, and cost-efficient optical links for data centers.
