Two current workforce problems were at the core of my research. First, in the Netherlands, as in many other developed countries there is a current malalignment between graduates’ preferences for medical specialties for their future career and societal needs in future medical specialists. Secondly, the pace in which the medical specialists workforce is diversifying, essential in striving for optimal care in a demographically and socially changing society, is lagging behind. So my research focussed on identifying mechanisms in medical specialty career choice and residency selection decision making process which could help us create a future adequate, diverse medical workforce.
