Pieter A. Doevendans became a cardiologist in Maastricht (trained by H. Wellens) after his medical training at the Leiden University. In 1993-1994 he had the opportunity to work with Ken Chien at UCSD San Diego where the work on embryonic stem cells started. The work was completed in Maastricht and provided the basis for a thesis on the function of the promoter of the atrial Myosin Light Chain gene. Upon return in the Netherlands he worked with Christine Mummery and Hans Clevers (Hubrecht Laboratory) on both human Embryonic as well as human Cardiac stem cells. In the meantime he remained active as an interventional cardiologist initially in Maastricht, but from 2002 on in Utrecht at the University Medical Center. Here he was appointed full professor in Translational Cardiology in 2004 and head of the department in 2005. The focus of the department of cardiology is on Cardiac Failure, stem cells and genetics. He was funded by various national and international foundations. Thus far he published more than 600 peer reviewed papers and 10 books. In 2012 he was appointed Chairman and Medical Manager Division Heart and Lungs, University Medical Center Utrecht. He is an active member of the European Society of Cardiology.
