During my Postdoc period I expanded my PhD work into a new research line, within the multi-modality medical imaging (M3i) group. In 2019 I was appointed as an Assistant Professor at the M3i group. In this role I’m continuing my work on investigating the interaction of blood flow and stents in relation to the durability of stents to maximize the outcome for patients. My work has a clear translational and applied focus, therefore I have an active secondment at the department of vascular surgery at the Rijnstate hospital.
To visualize and quantify blood flow I apply (and develop) several tools. In vitro we make use of laser particle image velocimetry techniques, realistic flow phantoms and flow circuits to simulate parts of human circulatory system2. In vivo we focus on the application of high frame-rate contrast enhanced ultrasound techniques3. Based on these techniques there are several project in which I’m involved:
- Stichting Lijf en Leven project, focusing on the relation between blood flow and disease progression in case of aortoiliac peripheral arterial disease. Funded by the stichting Lijf en Leven.
- ADEAR project, focusing on quantifying the in vivo deformation of endografts and in vitro interaction with blood flow at the timescale of a single heartbeat or breath cycle. Funded by the Connecting Industries Call and Terumo Aortic
- 2ACP project, focusing on optimizing the visualization of polymers used for injection in case of active sac filling. The second goal of the project is to investigate the mechanical interaction between the stent graft and polymer. Funded by the TKI-LSH PPP call from Health Holland and TripleMed Bv.
- Ultra-x-treme project, focusing on the development and application of 3D ultrasound based blood flow quantification aligned with biomechanical models for patient-specific characterization of cardiovascular status. Funded by NWO through the Perspectief program and several companies
- Vortecs project, focusing at obtaining 2D in vivo blood flow quantification, both with and without the use of contrast agents. Funded by NWO through the OTP program, next to Philips and Medtronic.
