Theses

Ali Caglar Özen was born in Turkey in 1988. He studied Electrical and Electronics Engineering between 2006 and 2010 at Bilkent University in Ankara, where he also obtained his Master's degree at the same department in 2013. He earned his Ph.D. degree from the Institute of Microstructure Technology at Karlsruhe Institute of Technology, Germany, in 2017.

In 2013 he joined the Department of Radiology, Medical Physics at the University Medical Center Freiburg as a research assistant. In 2017 he became a Post-doctoral Fellow at the German Consortium for Translational Cancer Research Partner Site Freiburg. Since 2021, he has been leading projects in the fields of MR safety, RF coil development for MRI, electromagnetic compatibility and MRI of tissue with ultra short T2 values in Medical Physics department of University Medical Center Freiburg. He has also been involved in scientific research and technology development in the fields of fast MRI, cardiovascular interventions, and MRI of myocardial infarction, MRI of 17O and 19F-labeled substances.

Dr. Özen is a member of the International Society of Magnetic Resonance in Medicine and is a School of Oncology Fellow of the German Consortium for Translational Cancer Research (DKTK). He was the recipient of the young investigator award of the European Society of Magnetic Resonance in Medicine and Biology in 2015. In 2019, he received the Lasby Fellowship from the University of Minnesota and joined the UMN as a visiting faculty. In 2021, he was awarded Senior Member title by the IEEE for his early career achievements.

He is the father of Umay (born in 11.12.2017) and the spouse of Seval Özen.
