David Ives

Place holder for mugshots 200x240Biography

David Ives was born in the UK. He received the BSc degree in physics from the University of Birmingham UK, in 1988.

He spent 21 years at the National Physical Laboratory in Teddington, UK, as part of the Photonics group. He mainly worked on the development of techniques for optical fibre and waveguide characterisation and optical fibre test equipment calibration.

In September 2010 he joined the Centre for Doctoral Training in Photonic Systems Development and obtained the degree MRes (2011) and PhD (2015). His PhD research was with the Optical Networks Group looking at the optimisation of wavelength routed networks to maximise data throughput while strongly considering the nonlinear transmission impairments for coherent optical communications. His PhD thesis titled "Coherent Optical Fibre Networking in the Nonlinear Regime" is available as a PDF.

He is currently working as a Research Assistant on the EPSRC funded project INSIGHT: Introducing Insight into the Abstraction of Optical Network Infrastructures. This joint project intends to merge the knowledge of physical layer transmission impairments from UCL with that of network virtualisation from Bristol University to create robust abstractions of the physical layer suitable for the creation and control of coexisting virtual networks.
