Profile

Ohis is a Chartered Engineer and Fellow of the Institution of Civil Engineers. He holds the Eur Ing (European Engineer) title and is a COREN Registered Professional Engineer (Engr) in Nigeria. Prior to his DPhil studies at Oxford he spent a considerable period of time in the industry working with Etteh Aro & Partners, Atkins, Halcrow and SKM (now both part of Jacobs) and Network Rail. During this time, he provided technical leadership on several major infrastructure projects across a number of countries and very often led large engineering teams to deliver a wide range of engineering projects, many of which were of crucial national importance.

Ohis holds an MSc with distinction in Major Programme Management from Pembroke College Oxford, an MSc with distinction in Civil Engineering from the University of East London and a BEng (Hons) in Civil Engineering degree from Ambrose Alli University Nigeria.

Current Research

Ohis’ doctoral research study, awarded the EPSRC scholarship, seeks to formulate system-of-systems methodologies for assessing the resilience of complex infrastructure networks with a specific focus on Britain’s rail network at national scale. This will involve an in-depth national scale modelling and stress testing of the rail network to assess its vulnerability and resilience under threat. It is hoped that this study which focusses extensively on the world’s oldest and pioneer railway network will inform the development of novel research methodologies that will make useful contributions to existing research knowledge.
