Joachim Wildberger

Professor

Joachim Wildberger is full Professor of Radiology and Chairman of the Department of Radiology and Nuclear Medicine at Maastricht UMC+. In addition, he serves as Director of the Division of Clinical Imaging and Diagnostic Laboratories at Maastrcith UMC+.

Graduated at the Rhenian-Westphalian Technical University (RWTH) in Aachen, Germany, he received his medical degree in 1994. After internships in Cardiology and Diagnostic Radiology (Mönchengladbach/ Leipzig), he started his residency in Diagnostic Radiology at the University Hospital Aachen. He was board certified for Diagnostic Radiology in December 1998, and became a fellow/staff member at this department thereafter. He received his PhD in Radiology in 2002, was appointed as vice-chairman of the department in 2006 and received a professorship at the RWTH Aachen in 2007. In July 2007 he became Head of Department, Diagnostic Radiology, HELIOS Klinikum Berlin-Buch, Charité Berlin, Campus Buch, Germany, before moving to his present position.

His per personal research topics are technical developments and functional imaging in computed tomography, contrast media research, cardiac imaging as well as image-guided interventions.

As PI for Imaging within CARIM he focusses on translational research, integrating different imaging modalities into the cardiovascular diagnostic chain, and favours multidisciplinary approaches to improve patient care.
