Personal details

BEng (H-W) PhD (Brist) PGCAP CEng MIMechE FHEA

I graduated from Heriot-Watt University in Edinburgh with first class honours BEng degree in civil engineering in 2009, being awarded the Watt Club Medal for achieving the greatest academic distinction on the course. I continued my studies at the University of Bristol, working on a multidisciplinary EPSRC-funded (EP/P50483X/1) PhD project supported jointly by the Department of Mechanical Engineering and the Department of Civil Engineering. The main focus of this project was vibration serviceability of structures, in particular pedestrian-structure interaction and the effect of this interaction on structural stability. This was motivated by the wobbly behaviour of the London Millennium Bridge on its opening day. I tackled this problem using a combination of analytical and numerical modelling of human gait, utilising fundamental models derived from the field of biomechanics, and empirical research conducted on a custom built experimental setup which is currently state-of-the-art (see below).

From the concept design to its realisation

The setup:

• offers a generous walking area;
• is capable of measuring pedestrian ground reaction forces directly;
• is supported on hydraulic motion base, allowing a variety of signals to be used as perturbation inputs;
• provides immersive and interactive virtual reality environment, overcoming the issue with incongruence of sensory information typical for tests conducted on a treadmill in laboratory conditions;
• incorporates treadmill speed feedback control mechanism, allowing automatic adjustment of the treadmill belt speed to that of the walker;
• incorporates an optical motion capture system, allowing kinematic data on pedestrian behaviour to be collected.

Soon before completing my PhD project in 2014, I took on a post of postdoctoral researcher within the Vibration Engineering Section at the University of Exeter and later another post of postdoctoral researcher at the University of Sheffield, both of which were funded via grants awarded by EPSRC (EP/G061130/2 and EP/I029567/1, respectively). I am now a member of the team behind VSimulators - an EPSRC-funded project aiming to create state-of-the art facilities for research on human factors engineering.

I was appointed a Lecturer in Structural Dynamics at the University of Leicester in September 2015.

A common theme for all my work in the field of human-structure interaction and biomechanics is the adopted complex system approach, acknowledging intricacy of human behaviour, in particular adaptability of human gait and its control requirements. I am now applying this approach to study crowd-structure system in order to capture any potential emergent phenomena and understand their consequences for the structural loading and response.

I hold a position of Visiting Fellow at the University of Bristol (since 2014) and a position of Guest Lecturer at the University of Leeds (since 2015).

I am a Chartered Engineer registered with the Engineering Council UK and a Member of the Institution of Mechanical Engineers.

Research

My research interests and activities revolve around the following themes:

• structural dynamics, in particular human-structure interaction, vibration serviceability and structural health monitoring
• crowd dynamics
• locomotor biomechanics, in particular stability and control of human gait and posture
• cognitive psychology, in particular integration of sensory information during the execution of motor tasks
• immersive technology
• complexity science
• sensors, instrumentation and signal processing

I am the Director of Biomechanics & Immersive Technology Laboratory, dedicated to fundamental and applied research on human behaviour utilising novel sensing technologies in real-life and immersive environments. I am also the Director of Dynamics, Vibration & Acoustics Laboratory, dedicated to fundamental and applied research on the design, performance and maintenance of structures and mechanical systems subjected to time-varying forces.

I am a member of the Artificial Intelligence Research Network hosted by the Leicester Institute for Advanced Studies.
