Parra Robles


Juan Miguel Parra Robles received a BSc in Physics (Universidad de Oriente, Cuba, 1995), a MSc in Electrical Engineering in Cuba (ISPJAM, Cuba, 1998) and a PhD in Medical Physics from Carleton University (Ottawa, Canada, 2004). He then joined Robarts Research Institute (London, Canada) as a postdoctoral fellow (2004-2007). In 2007, he received a Marie Curie Fellowship to work at the University of Sheffield, UK, where he later continued working as a Senior Research Fellow until January 2015. In January 2015, he joined the Department of Bioengieering and Aerospace Engineering at Universidad Carlos III de Madrid as a CONEX Professor. He has over 150 scientific publications including peer-reviewed journal articles and conference proceedings. Since 2011, he has served in the Executive Committee of the Hyperpolarized Media Study Group of the International Society of Magnetic Resonance in Medicine.


Research expertise focuses on the development of novel Magnetic Resonance (MR) imaging technology and its applications in biomedicine, with particular interest in the use of hyperpolarized gases. Areas of current research:

- Hyperpolarization of noble gases using the Spin-Exchange Optical Pumping (SEOP) method

- MRI imaging of lungs using hyperpolarized noble gases

- Novel hardware and acquisition/recontruction techniques for accelerated MRI and hybrid PET-MRI

- Theoretical models of non-Gaussian diffusion

- Finite Element Modeling of gas diffusion in lungs

- Quantification of lung microsctructure using diffusion MRI
