Biomedical Photoacoustics

Dr. Wenfeng Xiais a Senior Lecturer in the School of Biomedical Engineering & Imaging Sciencesat King's College London. 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 ofMedical Physics and Biomedical Engineering at University College London, UK. He joined King's College London in 2018 and immediatelyfunded thePhotons+ Ultrasound Research Laboratory (PURL), 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 howlight and sound interact with biological tissue, and how these interactions can be used for patient benefits. In particular, the research at PURL iscentered on the technological advancements and clinical translation ofphotoacoustics (also calledoptoacoustics), an emerging imaging and sensing technique that is based on light generated ultrasound.
