John Anders Tomas Nyberg
About
John completed medical school at Karolinska Institutet in Stockholm, Sweden, followed by internship at Herlev Hospital and Bispebjerg Hospital in Copenhagen. Thereafter, he worked as a cardiology resident at Zealand University Hospital, Roskilde and Køge, before starting as a PhD Candidate at NTNU in 2021.
His PhD project focuses on the development and clinical validation of new methods for quantifying myocardial function using echocardiographic deformation imaging and deep learning-based methods.
