Imaging in Neurodegenerative Disorders
- Our primary focus is on imaging and quantifying transition metal ion distribution in the human brain, with particular application to identifying change in neurodegenerative disorders.
- We measure the effects of regional brain iron changes on Magnetic Resonance Imaging (MRI) to explore biomarker potential.
- Our current collaborations include work on MRI methods for detection of Parkinson's disease and Alzheimer's disease.
- We use a variety of analytical techniques, including high resolution MRI, synchrotron X-ray microfocus spectroscopy, and magnetometry to characterize the distribution and form of trace metals in tissues and disease-related protein aggregates.
- January 2014: We are pleased to welcome Dr Simon Mitchell as a visitor to our group to work on a model of brain iron regulation in health and disease. Simon will be giving a seminar during his visit: details are at http://www2.warwick.ac.uk/fac/sci/eng/research/seminars/
- October 2013: We have been funded to set up a Warwick Medical Imaging Network (W-MIN) as a Science and Technology for Health GRP Network of Excellence. There will be monthly seminars and other activites throughout the year; email me if you want to join the mailing list, and keep an eye on the W-MIN website for details of events.
- July 2013: We have two undergraduate summer research projects running this summer, which include trying out some brain imaging sequences with volunteers on the clinical MRI scanners at UHCW and BUIC. Zobair Arya (Physics) is our current URSS student, and JP Hagen has a summer project bursary from the Warwick Materials GRP (jointly supervised by Prof Charles Hutchinson).
- February 2013: Congratulations to our URSS student, Kevin Ray, who has accepted a PhD project in the Department of Oncology at Oxford. His project is entitled 'Imaging the tumour microenvironment: novel multimodal approaches to spatially map metabolism, hypoxia, and pH'.
- March 2012: we are exhibiting our synchrotron research as part of the IOP stand, 'Visualising the invisible', at the Big Bang Fair, NEC, Birmingham.

Our primary focus is imaging and quantifying transition metal ion distribution in the human brain, supporting progress in early detection and diagnosis for neurodegenerative disorders. We use a variety of analytical techniques, including high resolution MRI, synchrotron X-ray microfocus spectroscopy, and magnetometry to characterize the distribution and form of trace metals in tissues and protein aggregates.
- Trace Metals in Medicine Laboratory, completed in 2011 and equipped for sample preparation and analysis. Resources include Class II cabinets, cryosectioning facilities for trace metals analysis in tissues, light microscopy, and freeze drying.
- MRI Probe (for imaging at 9.4 T): we recently obtained a state-of-the-art MRI probe for the 400 MHz spectrometer in Millburn House, under the Science Cities Translational Medicine 2 Programme. It is currently in use for in-vitro work.
- The Materials Characterization Laboratory, run by Martin Davis, is a School of Engineering resource providing a small materials analysis and imaging service. It is primarily run for the benefit of the School of Engineering staff and students; however, it also offers the same service to parties outside the University. Our speciality is in generating straightforward cost-effective reports with a quick response time when there is no need for accreditation.

Have you considered becoming a Science Technology Engineering and Mathematics (STEM) Ambassador? If you're reading this website there is a strong chance you are qualified. Click here to learn more about this national scheme. It's a great way to get involved in outreach activities in a way that fits with your schedule, and provides the structure and support that you need when you're getting started.
Our group participated in the Royal Society Summer Science Exhibition at the Southbank Centre in 2010, as part of the Diamond Light Source exhibit. This was a fantastic chance to introduce the research we do to the general public - and to meet some very familiar faces too!
Synchrotrons are large experimental facilities that provide an extremely intense source of light (primarily X-rays) that can be used for a very wide range of scientific investigations. In the UK, we currently have one synchrotron (Diamond), and there is a shared facility - the European Synchrotron Radiation Facility (ESRF) in Grenoble, France. There are further facilities around the world, including a large synchrotron (Advanced Photon Source) at the Argonne National Laboratory in the USA that our group uses for some of its work. Click on the logos below to learn more about each source.
ESUO (European Synchrotron Users Organisation)
The ESUO was founded in February 2010 at a meeting in Lisbon, and draws together representatives from countries throughout Europe to represent synchrotron X-ray facility users.
Joanna chaired the Diamond User Committee from 2009 - 2011, and subsequently represented the Spectroscopy Village of users at Diamond.
