Introduction
I obtained a Bachelor degree in Architecture and Civil Engineering from the University of Malta in 2002. From 2002 to 2008 I worked as a Structural Engineer in private practices.
In 2009 I obtained a Master degree in Structural Engineering from the University of Sheffield and in 2014 I obtained a PhD from the same University.
I am now working as a Research Associate at the Cambridge Centre for Smart Infrastructure and Construction in the University of Cambridge.
I am also a Director and founding Partner of Epsimon Ltd, a UK registered company offering instrumentation & monitoring services for civil infrastructure, including design, installation and operation of state-of-the-art monitoring systems, as well as related consultancy and training.

Distributed fibre optic sensing (DFOS) technology is being widely exploited in many civil infrastructure monitoring applications due to its inherent advantages over conventional sensing technologies. Over the last decade, research and development have enhanced the performance of DFOS systems in SHM, which led to new applications in civil engineerin...
The Civil Engineering Building was built between 2017 and 2019 to provide new office and laboratory space for the Engineering Department at the University of Cambridge, and to house the National Research Facility for Infrastructure Sensing (NRFIS). During the construction, monitoring systems using distributed fibre optic sensing (DFOS) and fibre Br...
Bridges are popular candidates for condition assessment and long-term monitoring because they are critical infrastructure components, while being accessible, visible, and usually publicly owned and operated. They represent the widest application of sensing technology, from traditional, mature, and reliable to novel, experimental, and (perhaps) less...
The precision error of the Brillouin optical time domain reflectometry (BOTDR)‐based distributed fiber optic strain measurement is normally evaluated based on strain change from the initial zero strain state. In many structural health monitoring applications, however, there is initial strain caused by the installation process of a fiber optic senso...
In this paper, we present an application of distributed fiber optic sensor (DFOS) technology to measure the strain of a continuous flight auger (CFA) test pile with a central reinforcement bar bundle, during a static load test carried out in London. Being distributed in nature, DFOS gives much more information about the pile performance as compared...
Distributed fibre optic sensing systems can measure strain and temperature at closely spaced intervals along a fibre optic cable. Distributed fibre optic sensor (DFOS) cables can be embedded in concrete piles and diaphragm walls during construction, in order to measure the temperature profile of the concrete during the curing process and the strain...
Distributed fibre optic sensing (DFOS) presents several advantages over traditional point sensors, for measuring strain and temperature in civil and geotechnical infrastructure. DFOS techniques use light transmitted through an optical fibre to enable measurements to be taken all along an embedded or surface-mounted fibre optic cable, which can be u...

Instrumented pile tests are vital to establish the performance of a pile and validate the assumptions made during initial design. Conventional instrumentation includes vibrating wire strain gauges and extensometers to measure the change in strain or displacements within a pile. While these strain and displacement gauges are very accurate, they only...

The floor-to-floor axial shortening of vertical load-bearing elements is an important factor in the design and construction of high-rise buildings. Contractors need to allow for the expected final compression of columns and walls due to superimposed load, concrete creep and shrinkage, particularly when installing finishes and partitions in lower fl...

A novel approach is being used to measure the progressive axial shortening of key structural elements of Principal Tower, a 50-storey reinforced concrete building in London, as it is being built. Distributed fibre optic sensor (DFOS) cables are embedded inside two columns and two core walls, from which the axial strain profile can be measured along...
Distributed Fibre Optic Strain Sensing for Monitoring Civil Infrastructure offers comprehensive guidance in the current developments of distributed optical fibre sensing applied to the field of civil engineering. The book discusses the concepts and practice of fibre optic monitoring of infrastructure and construction within the underground and geot...
Wireless Sensor Networks for Civil Infrastructure Monitoring provides expert guidance on the selection and use of wireless sensor network (WSN) technology for structural monitoring of both existing infrastructure and new construction projects. The purpose of this guide is to consolidate a generic methodology for the design and implementation of WSN...
In this paper we report on advances made in the installation and use of distributed fiber optic sensors to monitor reinforced concrete piles subjected to static load tests. Eight concrete test piles, at three construction sites in London, have recently been instrumented with embedded DFOS. The Brillouin optical time domain reflectometry (BOTDR) tec...
Structural monitoring of built assets, performed to ensure safety, usability, and to better understand the assets’ structural behaviour, is becoming common practice. One method to monitor structural behaviour is to use fibre optic systems to measure temperature and strain in structural elements. Fibre optic systems are relatively inexpensive, easy...
In this paper we present the use of distributed fibre optic sensor (DFOS) technology to measure the temperature and strain of reinforced concrete test piles during construction and during static load tests. Eight test piles were recently instrumented with DFOS, on three construction sites in London, by the Cambridge Centre for Smart Infrastructure...

In many cases, new tunnels in highly populated urban cities like London will need to be constructed underneath a dense network of existing tunnels to avoid them. The construction of new tunnels, however, inevitably results in ground deformations, which are transmitted to adjacent existing structures. The response of existing cast iron tunnels to tu...
The Crossrail project is currently the largest construction undertaking in Europe. It includes ten new rail stations, six of which are under central London, and 42 km of new rail tunnels weaving through the U.K. capital city's congested sub-terrain. The underground stations typically consist of a concourse tunnel in between two platform tunnels, al...
A study on the thermal performance of the Tamar Suspension Bridge deck in Plymouth, UK, is presented in this paper. Ambient air, suspension cable, deck and truss temperatures were acquired using a wired sensor system. Deck extension data were acquired using a two-hop wireless sensor network. Empirical models relating the deck extension to various c...

A pedestrian footbridge in Singapore was monitored for two weeks with a network of eight wireless accelerometer sensor nodes (Imote2). The nodes acquired 10 minutes of vibration data in the vertical direction every half an hour, processed the data using a novel embedded data processing algorithm and transmitted only the required results to the on-s...
The aim of this research was to investigate how wireless technology, combined with data
analytics, can be used for effective structural health monitoring (SHM) of civil
infrastructure. Two main applications were investigated, for which wireless sensor networks
(WSNs) were integrated into complete SHM solutions: (1) long-term quasi-static monitoring...

In order to be able to monitor the performance and health of a civil structure it is essential to understand how it behavesunder different environmental conditions. It is a well documented fact that the structural performance of bridges can bealtered considerably when they are subjected to changes in environmental conditions. This paper presents a...
Over the past couple of decades there has been an increasing interest in applying wireless technology to testing and monitoring civil infrastructure. The most commonly cited reason for this is the extra expense, time and difficulty (and sometimes impossibility) involved in installing a wired network of sensors. Consequently, a number of proprietary...
