Dr. Wenfeng Xia is a Lecturer (Assistant Professor) in the School of Biomedical Engineering & Imaging Sciences at King's College London. He is also the School International Lead. He received a BSc in Electrical Engineering from Shanghai Jiao Tong University, China, and a MSc in Medical Physics from University of Heidelberg, Germany, in 2005 and 2007, respectively. In 2013, he obtained his Ph.D from University of Twente, Netherlands. From 2014 to 2018, he was a Research Associate / Senior Research Associate in the Department of Medical Physics and Biomedical Engineering at University College London, UK.
He founded the Photons+ Ultrasound Research Laboratory (PURL) at King's College London in 2018, which brings together talented scientists who are committed to transform the ways that surgical and interventional procedures are performed via ground-breaking technological innovations. They are fascinated by how light and sound interact with biological tissue, and how they can be used for patient benefit. In particular, research at PURL is centered on the technological advancements and clinical translation of photoacoustics (also called optoacoustics), an emerging imaging and sensing technique that is based on light generated ultrasound.
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.
NAM TRUNG HUYNH
Nam Huynh is a senior research fellow in the Photoacoustic imaging group at the Department of Medical Physics and Biomedical Engineering, University College London. His research interests lie primarily in the area of instrumentations for novel imaging techniques using optics and ultrasound. He has been involved in developing high speed high resolution Fabry-Pérot clinical scanner and using the system to conduct patient studies over the last 7 years.
Dr Sacha Noimark received her M.Sci. degree in Chemistry with Mathematics from University College London (UCL) in 2010. Following, she received M.Res. and Eng.D. degrees in Molecular Modelling and Material Science (UCL). Her Doctoral research was focused on the development of light-activated antimicrobial polymers for healthcare applications. Dr Noimark joined the UCL Department of Medical Physics and Biomedical Engineering in 2014 as a postdoctoral researcher, after which she was awarded a Ramsay Memorial Fellowship (2016). Currently an EPSRC UKRI Innovation Fellow, her research interests are centred on the development of novel elastomeric nanocomposites to create new all-optical imaging and sensing technologies to guide minimally invasive surgeries. One of her key foci is the development of highly miniaturised optical ultrasound transducers, that can be fabricated by creating and applying specially engineered nanocomposites onto optical fibres. The optical properties of the nanocomposite coatings can be carefully tuned to strongly absorb visible light within specific wavelength regions for example, for optical ultrasound generation, and demonstrate transparency to light of other wavelengths, enabling combined imaging, sensing and therapeutics. These next-generation imaging and sensing technologies have applications in medical specialties ranging from gastroenterology to cardiology, opening up new avenues for clinical interventions.
James Joseph obtained his Bachelor’s degree in Electronic and Computer Engineering from the University of Nottingham in 2006. He obtained his Masters degree in 2007 and PhD degree in Biomedical Imaging from the School of Mechanical and Aerospace Engineering, Nanyang Technological University, in 2013. Further, he carried out his postdoctoral research for six years at Cancer Research UK Cambridge Institute and at the Department of Physics, University of Cambridge, under the mentorship of Prof. Sarah Bohndiek. Since July 2020, he has been working as a Lecturer in Biomedical Engineering at the University of Dundee. His research is focused on translational optical and multimodal imaging technologies. He also leads and directs the phantom development theme for International Photoacoustic Standardisation Consortium (IPASC).
