One of the key scientific challenges of the 21st century is to better understand the principles that allow a collection of neural cells to work as a fully functioning brain. The complexity of neurobiology, along with the range of possible parameters to be investigated means that new techniques are embraced and quickly incorporated.
A key aspect of the group’s research involves imaging small particles of diamond known as nanodiamond (ND). This material offers many advantages as a fluorescent label for biological applications. Its biocompatibility, potential sensitivity to electric and magnetic fields, lack of photobleaching and the possibility of targetting specific neural structures are all of particular interest to researchers in neurophysiology. By utilising Stimulated Emission Depletion (STED) microscopy, in conjunction with adaptive optics, it will be possible to image ND tens of microns into tissue with a resolution of 50nm. Achieving this resolution will allow imaging of synaptic sites, the anatomical features where signals are passed from one neuron to another, thereby allowing a better understanding of the propagation of information through the brain.
Successful candidates will gain a wide range of experience in skills such as:
- Optical hardware design and alignment
- Developing software for hardware control and data processing
- Labelling samples for imaging
- Collaboration with colleagues in the biological sciences to ensure our research also enables new biological science
