Alexander Guimaraes, PhD, MD

Associate Professor, Department of Diagnostic Radiology, Oregon Health Sciences University, Portland, OR, USA

I am a board certified radiologist with 20 years of experience in magnetic resonance imaging, 10 years of experience as a physician practicing diagnostic and interventional radiology, was the Medical Director at the Martinos Center for Biomedical Imaging at the Massachusetts General Hospital and have recently accepted a position as Chief of Body Imaging at OHSU.  My interests are in the development and translation in humans and preclinical murine models of cancer,  novel MRI and PET/MRI techniques for robust and reproducible quantification of response to targeted chemotherapeutic strategies.  Towards that end, I currently apply MRI using magnetic nanoparticles to study tumor microvasculature as a surrogate to targeted response to collagen disruption and immune modulation strategies in murine models and humans with pancreatic cancer.  Furthermore, I serve on committees within the Society of Abodminal Radiology, ISMRM and as Chair of the MRI coordinating committee for the RSNA Quantitative Imaging Biomarkers Alliance, which provides me an opportunity to industrialize imaging biomarkers during their utilization in clinical trials.
