Academic Career and Research Areas

Professor Herzen (*1980) conducts research on biomedical imaging. The main focus of her research is the development of new methods in X-ray computed tomography based on spectral detection and X-ray phase contrast for medicine and biology. She uses both, highly-brilliant synchrotron radiation and standard polychromatic X-ray tubes for her research. Besides the improvement of image quality, another major objective of Herzen’s work is quantitative imaging – a procedure which allows for extracting element-specific measures from X-ray images.

Professor Herzen studied physics at the University of Hamburg (2006) and obtained her doctorate – which included a research stay at the Paul Scherrer Institute (Switzerland, 2008) – from the Helmholtz-Zentrum Geesthacht in 2010. She then worked as a post-doctoral researcher at TUM (2010 & 2014) and at the synchrotron source PETRA III (Hamburg, 2012) and held a position as interim professor at TU Dortmund (2015) before being appointed as Assistant Professor for Biomedical Imaging Physics at TUM in 2018.
