Current Research Interests
X-ray microscopy, instrumentation and method development, studies of trace metals in biological samples.
Hard x-ray nanoprobes are currently being built around the world to provide high spatial resolution x-ray microscopy. These tools will allow us to probe structural and chemical variations in a wide range of samples with a 50 nm or smaller probe. This is an emerging field and a new tool for the science community and our aim is to deliver instrumentation, sample preparation and data analysis tools which open this tool to the broadest community and best scientific problems.
Using I18, the microfocus spectroscopy beamline, we've studied the affect of metal nanoparticule debris from metal on metal hips on tissue surrounding the hip. We identfied metal species in the tissue and they are co-located with particular cell types but we didn't have the spatial resolution to clearly resolve how individual cells take up the metal. I14 will be able to address this issue by providing a high resolution probe (50nm) capable of probing a range of materials in fine detail.
I am also interested in algorithm development for fast XRF data processing and XRF tomography.
