MD PhD M. van der Valk (Improving the understanding and management of co-morbidity and co-infection in people living with HIV)

 Since the inception of the AGEhIV cohort study in 2009 I have together with the study PI prof. P. Reiss (Professor of Internal Medicine, in particular the complications of HIV treatment), acted as a senior clinical co-investigator of the study contributing to the design and excecution of a range of studies performed by successive PhD students on the study. (www.agehiv.nl)

 I act as the principal investigator of the MC Free study which aims to eliminate hepatitis C infections in hiv-positive men who have sex with men. 

In line with this implementation research project I am currently initiating together with prof. F. van der Waals (professor in GlobalHealth education) an HIV 'test-and-treat' implementation research project on Bonaire.
