Hector Dejea is a PhD student in the X-ray Tomography Group at Paul Scherrer Institut and ETH Zürich since 2017. Before that, he received his Degree in Biomedical Engineering from Universitat Pompeu Fabra (Barcelona, Spain) in 2015 and his MSc in Biomedical Engineering - Bioimaging from ETH Zürich in 2017.

Scientific Research

Hector’s research focuses on the application of synchrotron radiation imaging for the study of cardiovascular diseases, including the design of X-ray imaging setups and protocols as well as image processing tools for the quantification of cardiac structure. This includes the study of human cardiac biopsies and transmural pieces, as well as ex-vivo and in-vitro rodent models of cardiovascular disease.

Hector's PhD is carried out in collaboration with the UniversitätSpital Zürich (Zürich, Switzerland) and the University Hospital Centre Zagreb (Zagreb, Croatia), and he is also actively involved in several projects together with IDIBAPS (Barcelona, Spain), Universitat Pompeu Fabra (Barcelona, Spain), University College London (London, United Kingdom), and the Computer Vision Lab in ETH Zürich (Zürich, Switzerland).
