Dr Guilhem Collier is a Senior Research Scientist in the School of Medicine and Population Health at the University of Sheffield. He graduated with a double MSc degree from the ENSPG Physics engineering school in Grenoble and from the Royal Institute of Technology in Stockholm. He completed his Marie-Curie PhD programme at the Atomic Optics department of the Jagiellonian University in Krakow on the subject of “Metastability Exchange Optical Pumping of 3He in situ”. He joined the POLARIS group of the University of Sheffield in 2012.
His research interests focus on the development and optimisation of MR imaging methods for functional and structural imaging of the lungs with hyperpolarised gases and proton MRI. Current projects include dissolved xenon imaging to assess gas transfer impairment in the lungs of subjects with different diseases such as long COVID, IPF/ILD and asthma/COPD, as well as image analysis and image registration for regional comparison of quantitative parametric maps of lung function. He has contributed to numerous publications on topics including hyperpolarized 129Xe MRI abnormalities in patients after COVID-19 pneumonia, dissolved 129Xe lung MRI for quantification of regional gas transfer in idiopathic pulmonary fibrosis, and various aspects of hyperpolarized gas MRI techniques and applications in pulmonary imaging.
