Background
Information
Dr Paul Wright gained a BSc (Hons) in Pure & Applied Physics from
the University of Nottingham in 1993 before undertaking postgraduate research
in medical physics at the University of Exeter. On completion of his PhD he
moved to the University of Teesside, as a lecturer in the Division of
Measurement & Control, where he taught various aspects of measurement
science, optoelectronics and research methodology. Paul spent 5 years with Land
Infrared as a development engineer, working primarily on near-infrared
temperature measurement systems, before joining the then Industrial Process
Tomography group at UMIST in 2002 to work on
laser-based measurement in combustion systems. He is currently a lecturer in
the School of Electrical & Electronic Engineering, with research interests
spanning several areas of measurement electronics. Paul has designed numerous
optical and electronic instruments and his publications and patents include
work on vibrotactile and electrotactile
perception, near-IR thermometry, optical tomography and medical
instrumentation.

Research
Interests
Paul’s research interests
lie primarily in the areas of mixed-signal circuit design, instrumentation and
optoelectronics. He has worked extensively in optical measurement, across the
visible, infrared and terahertz bands, and in several areas of biomedical
instrumentation. He is particularly interested in the development of
instrumentation for challenging heavy industrial and clinical environments.
Optical
tomography
Laser absorption techniques
can be used to measure the concentration, temperature and pressure of
particular chemical species within mixtures of gases. By combining these
techniques with tomographic methods, gas distributions can be imaged. It is
also possible to construct images based on optical scattering, fluorescence or
incandescence.
Paul is currently a
co-investigator on FLITES, a £2.7M EPSRC collaboration involving 4 UK academic institutions
and 6 industrial partners. This consortium is currently commissioning jet
exhaust emissions imaging systems at the Spanish national aero engine test
facility in Madrid, establishing a globally unique capability. Previous
projects in this area include IMAGER,
a DTI Link project that imaged fuel vapour distribution within one cylinder of
an internal combustion engine during operation, and 2-ACE, measuring both hydrocarbons and product water vapour in HCCI combustion.

Electrical impedance
tomography (EIT)
EIT can be used to estimate
conductivity distributions within objects. The technique has applications in
both medical and industrial imaging.
Paul is currently
developing the instrumentation for R3M
(‘Robust Repeatable Respiratory Monitoring with EIT’),
a £1.9M EPSRC-funded study which brings together
electronic engineers, mathematicians and clinicians to develop and evaluate
advanced bioimpedance-based tools for lung-function
monitoring in critical care contexts. He is also the designer of the fEITER instrument, used to investigate the potential of EIT for functional imaging of the human brain.

Fibre optic deformation sensors
Paul’s work on ‘magic carpet’ fibre optic
deformation sensors has attracted substantial media attention and was selected as
one of just five innovative UoM projects exhibited at
the 2013 Conservative Party Conference, attracting the attention of the then
Minister of State for Universities and Science, David Willetts. A recent
article (Cantoral-Ceballos et al [2015]) describing their application to gait analysis was
among the 50 most downloaded papers from the IEEE Sensors Journal during
January and March 2015.

Wireless sensor networks
Use of
low-cost wireless transceivers to create distributed sensor networks.
Optical thermometry
Studies of the optical
emission properties of industrially-significant materials, particularly
aluminium alloys, under processing (e.g. hot-rolling, extrusion, forging) and
the application of this to improved process temperature measurement.
Measurements of vibrotactile
perception
Investigation of how
complex vibrational stimuli are interpreted within the human vibrotactile 'channel'. This highly interdisciplinary study
combined aspects of vibrometry, control engineering,
signal processing, physiology and psychology.

Outside
interests
Paul lives in Sheffield, on the edge of Peak
District National Park, with his wife and two daughters.
He is a keen skier and climber, having learned both in his native
north-east as a child, and can often be found bouldering on his local crags.
