Kerstin Hammernik

I received a BSc and MSc in Biomedical Engineering from Graz University of Technology in 2011 and 2015, respectively. Currently, I'm a research assistant and PhD student supervised by Prof. Thomas Pock at the Institute of Computer Graphics and Vision, Graz University of Technology. My current research interests include optimization and learning of variational models with application to medical inverse problems such as magnetic resonance (MR) and photoacoustic image reconstruction. A list of publications can be found here and on my Google scholar page.
