Wiendelt Steenbergen is professor in Biomedical Photonic Imaging in the Faculty of Science and Technology at the University of Twente, and Vice-dean Research in the same faculty. He obtained an MSc degree in Aerospace Engineering at the Delft University of Technology (1988), a PhD degree in fluid dynamics at the Eindhoven University of Technology (1995) and joined the University of Twente, Enschede (the Netherlands) as postdoc. In 2000 he was appointed assistant professor in biomedical optics and broadened his scope to low-coherence interferometry and photoacoustic and acousto-optic imaging for biomedical purposes. In 2010 he became full professor and group leader of the Biomedical Photonic Imaging group of the University of Twente. His current research interests are speckle based tissue perfusion imaging, combined photoacoustic and ultrasound imaging, tissue perfusion imaging using infrared radiation, and quantification of photoacoustic imaging using acousto-optics. His current medical interest areas are the diabetic foot, transplant surgery and dermatology.
