Researcher biography
Dr Kieran O'Brien is a Siemens Healthcare Adjunct Research Fellow at the Centre for Advanced Imaging. He completed his Bachelor of Biomedical Engineering (Honours, 2005) and PhD in Bioengineering from the University of Auckland in 2009. After being awarded his PhD Kieran worked in Postdoctoral positions at the University of Auckland and the University of Geneva Centre d'Imagerie BioMédicale before joining Siemens as a Senior Scientist in 2013.
His research interests are include improving RF pulses at high field (≥3T) to overcome imaging inhomogeneity and B1 limitations for Neuro, MSK and Cardiac applications; bi-exponential diffusion imaging; and, phase imaging for quantitative susceptibility mapping and measuring motion.
