Personal profile

Research interests

The application of shaped laser beams to trap, analyse and manipulate collidal particles, cells and tissue. Our work includes optical tweezers and particle rotation with applications in biophotonics, studies of novel light beams (including Bessel beams, Airy beams, Laguerre-Gaussian beams), shaping light through disordered materials, advanced imaging, Raman analysis, cell nanosurgery.

Teaching activity

I am very passionate about teaching and innovation in communicating science. I deliver two lecture courses with colleagues at St Andrews, each of which i instigated, namely "Biophotonics" and "Applications of Quantum Physics". I have also designed and implemented optical trapping systems for the undergraduate and Masters Course laboratories.I also undertake various tutorials and postgraduate teaching activities
