Research activities in my group cover the area of biophotonics at the interface between life and physical sciences. In collaboration with the School of Physics and Astronomy, my research work includes:
- development of a new generation laser-scanning multiphoton microscope based on Coherent Anti-Stokes Raman Scattering (CARS) for label-free studies on living cells
- development of a multiphoton optical microscopy (four-wave mixing imaging) based on the resonant nonlinear emission of colloidal nanocrystals (semiconductor quantum dots and metallic nanoparticles)
- development of optical biosensors for sensitive detection of biomolecules using plasmonics sensing with metallic nanoparticles or whispering-gallery modes of microspheres
- time-resolved fluorescence resonance energy transfer (TR-FRET) as a probe of biomolecular interactions
In September 2011 we held the first Bio-Nano-Photonics Symposium at Cardiff University. A second symposium was organised in September 2013. A following event will be organised in September 2015.

I did my undergraduate in Physics at the University of Florence (Italy) and then received the Diploma and the Ph.D degree in Physics in 1993 and 1997 respectively. From 1997 to 1999 I was Assistant Research Professor at the Technical University of Denmark (Kgs.Lyngby, Denmark).
From 1999 to 2004 I worked as Senior Scientist and EU Marie Curie Fellow (2001-2003) at the Physics Department of Dortmund University in Germany where I received the Habilitation degree in Physics (Venia Legendi) in 2003. During this time I was interested in the experimental investigation of the optical properties of novel semiconductor nanostructures, such as quantum wells and quantum dots. In particular, I developed a new technique for ultra-fast coherent laser spectroscopy of these nanostructures.
From September 2004 I moved to Cardiff University as Senior Lecturer. On August 1st 2007 I was promoted to Reader and on August 1st 2011 to a Personal Chair.
Anrhydeddau a Dyfarniadau
I received the Marie Curie Excellence Award from the European Commission during the official award ceremony at the Ecole Polytechnique Federale de Lausanne on the 16th November 2006.
Marie Curie Excellence Awards (EXA) aim to give public recognition to outstanding past achievements of scientists who have reached a level of exceptional excellence in their given field. Up to five prizes of 50 000 Euros each are awarded every year.
Since October 2010 I am an EPSRC Leadership Fellow.
I am Scheme Coordinator of the new MSc in Biophotonics.
Coherent Anti-Stokes Raman Scattering microscopy for non-invasive imaging of living cells
Optical microscopy is an indispensable tool for cell biology. Different microscopy methods are currently available and continuous effort is devoted to develop new techniques with improved sensitivity, selectivity and/or spatial resolution. An important issue in recent microscopy is the ability to perform non-invasive studies avoiding the need for fluorescent probes that are prone to photobleaching and can perturb the cell functions.
Together with Prof. Wolfgang Langbein who is appointed in the School of Physics and Astronomy, we are developing a new generation of laser-scanning multiphoton microscope based on Coherent Anti-Stokes Raman Scattering (CARS, see figure below) with improved sensitivity and chemical specificity for real-time studies on living cells. Such an instrument allows non-invasive microscopic examination of cells and subcellular structures under physiological conditions without the need to stain or express tagged proteins.
My research plan is to develop a new generation of laser-scanning multiphoton microscope based on Coherent Anti-Stokes Raman Scattering (CARS).
