I was born in Guatemala, received my training in Diagnostic Radiology at the University of Miami followed by a 2-year fellowship in Neuroradiology at Emory University in Atlanta. For a short 18 months I was an Assistant Professor of Radiology at the University of Texas in Houston and then became Chief of the Division of Neuroradiology and Professor of Radiology at the University of North Carolina in Chapel Hill a position I have held for 21 years. My list of publications includes over 570 articles (peer review and invited) as principal or co-author and 16 books with the 4th edition of Neuroradiology Companion published September of 2011. I have given over 820 invited lectures in the last 12 years. Currently, I serve as a member of the ARRS Executive Council, ASNR President, and Editor in Chief of the American Journal of Neuroradiology. I travel extensively and for information regarding my travel schedule and conferences available click on "Travel Schedule & Conference List" on the navigation panel (left, below QR code).
