Open PhD Opportunities

Learning how we walk:

With 33 joints and 29 muscles our feet are incredibly complex, and despite having learnt to walk upright thousands of years ago, humanity still does not fully understand how we use our feet to balance. State-of-the-art gait analysis (the study of how we walk) instrumentation either treats the forces exerted by the foot on the floor as a single point (force plate) or measures the pressure exerted by different points of the foot (pressure mat/insoles). This limits the information that we can acquire on the foot-floor forces, which in turn limits our insight into how our feet interact with the floor to balance ourselves. Overcoming this this is vital to tackle the high incidence and impact of falls in our ageing society.

In your PhD, you will join our interdisciplinary team based in Durham, Newcastle and London to develop new instrumentation to revolutionise our understanding of how our feet enable us to balance and move around, impacting a diverse range of rehabilitation and sports applications. Whilst this PhD project focus on the instrumentation development and data analysis you will also as grow your expertise in movement biomechanics.

High bandwidth optical communications between ground and space:

Free Space Optical Communications systems have the potential to revolutionise communications by providing high bandwidth, low-latency internet to anywhere on the globe, without the limitations of spectrum licensing. However to ensure robust connections, they must operate continuously when clear skies are available. This is a challenge due to the adverse effects of atmospheric turbulence which add wavefront distortions to the propagated laser beam, hence fades on the uplink and downlink beams.

Adaptive optics technologies are required to compensate for the atmospheric turbulence. Normally, this works by sensing the wavefront distortions caused by the atmospheric and compensating by applying correction to the beam. However, wavefront sensors make the system more complicated and are prone to errors in the strong turbulence encountered when aiming for 24/7 continuous operation.

In this project, we will develop fast iterative adaptive optics techniques to compensate the beam, such that the correction is quickly optimised by observing a suitable performance metric. Computer simulations will be performed to select suitable algorithms and correction hardware, then demonstrations performed in the laboratory.

Sensing the atmosphere with UAVs:

Astronomical observatories have to correct for it, life on Earth depends upon it, the Earth’s atmosphere is a dynamic system, changing over different timescales, distances and altitudes. Historically speaking, mapping out atmospheric conditions occurs at ground level with a variety of technologies, in the lower atmosphere along a line of sight, or vertically through one-way balloon based. None of these approaches allow us to create a three dimensional map of atmospheric composition.

In your PhD you will look to take advantages in UAV (‘drone’) technology, combined with astronomical instrumentation, to create a UAV-based system that will utilise direct sensing and remote sensing techniques to map out the three dimensional distribution of atmospheric gas and dust content. Crucially, the performance of the system will be quantified, providing a clear understanding of the sensitivity and accuracy of the UAV system. Working with international partners, the student will then look to fly the calibrated system instrumented testing ranges.

Scalable Satellite Sensor:

With the space industrial revolution rapidly driving down launch costs, there has been a surge in the number of artificial satellites launched into orbit. This rapid development of the space sector results in major challenges and risks if we do not maintain the space environment in a sustainable way.  Our access to space could be dramatically reduced in the next decade through populating orbital space with debris from high-speed collisions or other fragmentation events, or through malicious activity. To support a sustainable space sector requires independent and scalable monitoring of satellites, measuring real time dynamics and “pattern of life” behaviour.  Measuring the orbital dynamics includes monitoring satellites moving in non-Keplerian orbits during manoeuvres to avoid collisions, in-orbit servicing and debris removal, whilst “pattern of life” monitors and identifies changes in their physical properties or behaviour.

This proposal aims to develop and test the technology to detect and monitor the dynamics and physical structures of satellites in real time.  We will establish proof of principle for the technique and create the infrastructure needed for space sustainability research, commercial operators, and for the defense sector. The vision for this proposal is to develop a scalable technology needed to monitor and characterise objects in orbit (including active satellites, defunct satellites, debris, and rocket bodies).

The project will involve modelling of the space environment, assessment of current space monitoring capabilities, design and development of ground-based optical instrumentation, and sophisticated data analytics (astrometry, photometry, ray tracing and machine visions) to extract information from large volumes of data.
