Dr. Ir. Lennard Voortman
I have a background in applied physics (TU Delft), where I focused on image analysis in the group of Lucas van Vliet. My PhD research involved image formation in cryo-electron tomography, which was a joint collaboration between Bram Koster (LUMC) and Lucas van Vliet (TU Delft). The project was part of an industrial partnership programme with FEI Company (now part of Thermo Fisher). After finishing my PhD thesis I started working as application specialist at Delmic, a start-up company in Delft that produces integrated correlative light and electron microscopes. During my time at Delmic, I was closely collaborating with the group of Pieter Kruit and Jacob Hoogenboom (TU Delft), where I worked on projects involving electron-beam induced super resolution and multi-beam SEM imaging.
At the end of 2016 I started at the Leiden University Medical Center as the head of the light microscopy facility. Here I am working on maintaining and improving the scientific impact generated and facilitated by the microscopy facility, as well as providing support with image analysis and quantification.
