Invert is a group at the University of Bath studying inverse problems and tomography over a range of scientific fields, including navigation, space science, and medical imaging. Despite this wide range, many of the problems we solve have strong mathematical similarities. Our research often involves exploiting these connections, to develop techniques which can be applied to many fields. Our research can be grouped into four broad categories:

Industrial tomography Medical and biological imaging
There is growing interest in using realtime tomography to monitor complex industrial processes. Our research concerns novel methods, such as electrical impedance tomography, electrical capacitance tomography, ultrasound tomography and cosmic-ray muon tomography. In addition to building state-of-the-art prototype devices, we are working to improve the complex mathematical algorithms which underlie these forms of tomography. (More...) Tomographic imaging is of vital importance to modern medicine. We are developing techniques to increase image contrast, avoid imaging artifacts, and increase the usability of techniques such as SPECT. We are also applying tomographic imaging to biological research topics, such as the development of bee brains, the internal behaviour of beehives, and the anatomy of prehistoric insects trapped in amber.

Positioning navigation and timing Space weather and the ionosphere
Modern transportation is reliant on accurate radio-based navigation systems. Technologies such as telecommunications similarly rely on high-precision radio timing signals. We are working to improve and guarantee this accuracy, by understanding, mapping and predicting phenomena such as unwanted reflections, ionospheric effects, and interfering radio sources which can disrupt the signals. (More...) Space weather (the dynamics of the region surrounding the Earth, as it interacts with the Sun) can interfere with communications, damage satellites and overload electrical grids. Invert is particularly interested in the ionosphere, and has developed techniques to generate 3D maps of ionospheric electron density. We are also deploying scintillation receivers around the globe, to measure the ionosphere's effect on radiowave propagation. (More...)

News and updates

March 2011: Expedition to Cape Verde

Christopher Benton and Jenna Tong have returned from Cape Verde, after performing experiments at the Cape Verde Atmospheric Observatory. The main purpose of their visit was to set up a GNSS scintillation receiver, for detecting and studying space weather events. (More...)

Mar 2011: TOPCAT satellite experiment chosen to fly

A team from the Invert group have been chosen to fly their payload (TOPCAT) on the UKube-1 satellite. Along with three other experiments, it was chosen from a range of proposals made by companies and academia. UKube-1 is a CubeSat (a type of miniaturised satellite) and will be operated by the UK Space Agency. The TOPCAT payload is being developed by first year PhD student Talini Pinto Jayawardena, together with staff members Cathryn Mitchell, Robert Watson and Julian Rose. It will study the plasmasphere and the upper ionosphere. (More...)

Jan 2011: Joe Kinrade returns from Antarctica

Joe Kinrade has returned from Antarctica, on a mission to service and retrieve data from Invert's network of GPS scintillation receivers. He also installed a new receiver at the Rothera Research Station. (More...)
