Randi Drees - Contributor Profile

Bio

Randi graduated from the Freie Universität Berlin, Germany in 2001. She pursued her doctoral thesis funded by a stipend through the Sonnenfeld-Stiftung Berlin in a cooperation between the Radiology Department of the Humboldt Universität Berlin and the Anatomy Department of the Veterinary School of the Freie Universität, Berlin. Randi then spent time in private practice before pursuing her Diagnostic Imaging residency at the University of Wisconsin-Madison, USA.

She became board certified with the European College of Veterinary Diagnostic Imaging and American College of Veterinary Radiology in 2008. Randi then pursued an alternative training program in Veterinary Radiation Oncology at the University of Wisconsin-Madison, USA and became board certified with the American College of Veterinary Radiology (Radiation Oncology) in 2012. She held a clinical assistant professorship and was section head of the diagnostic imaging section at the School of Veterinary Medicine at the University of Wisconsin-Madison, USA before relocating to the RVC.

Randi has completed her PhD in cardiovascular imaging with the University of Gent, Belgium in 2015. She is a member at large of the board of the ECVDI and member of the radiation oncology education and credentials committee establishing an add-on Training program in Radiation Oncology for Diplomates of the ECVDI and ECVIM colleges and the past president of the CT/MRI society for the ACVR.
