    Research interests

    My research interest is in optical system development for use in biology and medicine. My research topics cover ultra-violet wavelength imaging systems, photolithography, optical theory, nanoscopy for pathology, and light-sheet microscopy. 

    I lead EU and NRC funded research projects on UV microscopy development (MitoQuant) and light-sheet microscopy development (SOLIS).
