Side Activities

In 2018, I have documented my side activities as CSO at SentryX, a spin-out company of the UMC Utrecht. In 2018 SentryX has, with support/supervision of the Utrecht Holdings, reached a license agreement and collaboration agreement with the Division of Surgical Specialties of the UMC Utrecht (signed off by J. de Graaf). The side-activities have also been approved (and filled out in the SAP personal fiels) the same year by, then, Head of Department of Orthopaedics (R.M. Castelein).
