February 2023 – Didcot Cafe Scientifique – James Kwan, The humble bubble
21st February 2023 @ 7:30 pm - 9:00 pm
In-person talk at Cornerstone Arts Centre, Tuesday 21st February 2023 at 7.30pm
‘The humble bubble’
Nature hates bubbles. So, making new bubbles takes a lot of work, and will ultimately violently collapse in on themselves. These imploding bubbles can melt nearby steel surfaces, create light, and even break down molecular bonds. By engineering bubble collapses with sound, we can tune these effects for a specific application. In this talk, I want to share how my research group is developing novel methods to take advantage of these interactions to tackle health and environmental challenges, specifically focusing on two applications: enhancing drug delivery and improving chemistry.
James Kwan is also an Associate Professor at the Department of Engineering Science at the University of Oxford and a Tutorial Fellow at Balliol College. He is part of the Physical Acoustics Lab (PacLab). His research interests include the application of mechanical, thermal, and chemical effects of ultrasound and cavitation to address challenges in personal and environmental health.
He was awarded the W.W. Spooner Junior Research Fellowship at the University of Oxford for his work in ultrasound-based strategies for drug delivery. From 2016 to 2020, James was an Assistant Professor at the School of Chemical and Biomedical Engineering at Nanyang Technological University Singapore (SCBE). James’ work to date on ultrasound and cavitation has resulted in invited presentations and lectures around the world, peer-reviewed journal articles in prestigious journals such as Ultrasonics Sonochemistry, Journal of Controlled Release, Small, and Theranostics, and co-authored book chapters. He is also part of the Editorial Board of Ultrasonics Sonochemistry. Additionally, he has applied for numerous patents, two of which have been awarded and are now licensed to separate spinout companies in the USA and UK.
