Lidia GaldinoBiography

Lidia Galdino received her BEng and PhD degrees in electrical engineering from the University of Campinas - UNICAMP, Brazil, in 2008 and 2012 respectively. Her PhD research focused on the investigation of a new all-optical technique base on a fiber four-wave mixing (FWM), to convert and regenerate on-off keying (OOK) and differential phase-shift keying (DPSK) signals into incoherently optical code division multiple access (OCDMA) signals. She focused on the format conversion with simultaneous regeneration of signals crossing the borders between metropolitan area network (MAN) and access networks.

She joined the Optical Networks Group at UCL in 2013, to work on the UNLOC project. She is working on maximising the capacity of optical fibre communication systems, focusing on numerical and experimental study of advanced modulation formats and their effectiveness in maximising spectral efficiency over long-distance transmission. She will consider the use of optimised constellations, non-necessarily uniform, in achieving this goal.
