# Washington Yotto Ochieng

Washington Yotto Ochieng is a Kenyan-born British academic who is Head of the Department of Civil and Environmental Engineering at Imperial College London. Previously, he was Head of the Centre for Transport Studies and Co-Director of the Institute for Security Science and Technology(ISST) together with Deeph Chana. Ochieng is the interim Director of ISST. He also serves as Director of the Engineering Geomatics Group and Chair of Positioning and Navigation Systems. In 2024, Ochieng became the President of the Royal Institute of Navigation.

## Early life and education

He is the son of Michael Yotto Amoko and Grace Akumu Yotto (née Radigo). He earned his BSc (First Class) in Engineering from the University of Nairobi in 1988, before moving to the United Kingdom where he studied for an MSc (distinction) at the University of Nottingham. He went on to a study for a PhD in Differential GPS (DGPS) and fiducial network design.

## Personal life

In 1997, Washington Ochieng married microbiologist and science teacher, Abosede Ochieng (née Salako). They have two children.

## Research and career

Ochieng remained at Nottingham as a postdoctoral research associate after his PhD, before joining Thales Group as a navigation engineer. Ochieng joined Imperial College London in 1997. He works on the design and application of navigation systems, and hopes to achieve a truly global position, navigation and timing (PNT) system. Professor Ochieng works in the area of intelligent traffic control especially Smart Intermodal User-Centric Mobility and how it can be used in security and to regulate traffic in congested streets and railways, as well as in air traffic management and maritime management. He has been involved with several international projects, including European Geostationary Navigation Overlay Service (EGNOS), Galileo, global navigation satellite system (GNSS) and the Single European Sky ATM Research (SESAR) joint undertaking. For the GNSS system, Ochieng worked on sensing, modelling of errors in the positional accuracy and ultra-wideband radio systems. He has been involved with the transformation of London's transport system and introduction of the London Congestion Charge.
He was promoted to a Chair in Positioning and Navigation Systems in 2007. In 2021, he became the Vice President of the Royal Institute of Navigation (RIN ) and President in 2024. His focussed research is into the development of tools that help to shape the thinking of societies in the design and building of infrastructure resilience and security; smart user-centric intermodal mobility and; Positioning, Navigation and Timing (PNT) systems.
At Imperial College London, Ochieng is part of the Engineering and Physical Sciences Research Council (EPSRC) Centre for Doctoral Training in Sustainable Civil Engineering. He has advised on algorithms that can support the navigation of satellites.
In 2021, Ochieng was an expert witness on UK space strategy and UK satellite infrastructure at the Parliamentary select committee on science and technology.
