Research
Overview
Callum’s research is focused upon hyperpolarisation of more insensitive nuclei such as 15N. This involves developing the signal amplification by reversible exchange (SABRE) hyperpolarisation method to optimise polarisation transfer to 15N, and other nuclei in various substrates for use in reaction monitoring, mixture analysis and medical imaging.
The main aim of his project is to prove the existence of the NMR silent paranitrogen with the ultimate hope of utilising the hyperpolarization potential of p-N2 to develop a new technique for imaging the lung space via MRI.
