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

Interested in joining my lab as a self-funded post-graduate student or a postdoc/fellow?  Please contact me by email.

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.

Honours and awards

In 2015 I received the Royal Society Wolfson Research Merit Award. Jointly funded by the Wolfson Foundation and the Department for Business, Innovation and Skills (BIS), the scheme aims to provide universities with additional support to enable them to attract science talent from overseas and retain respected UK scientists of outstanding achievement and potential.

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 a PI in the Initial Training Network FINON (Female Investigators in Nonlinear Optical Nanoscopy)

Projects

Coherent Anti-Stokes Raman Scattering microscopy for label-free 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 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 structure and function.

Together with Prof. Wolfgang Langbein who is appointed in the School of Physics and Astronomy, we have developed a range of home-built laser-scanning multiphoton microscopes based on Coherent Anti-Stokes Raman Scattering (CARS), enabling rapid label-free chemically specific microscopy of living cells and tissues. A second-generation CARS microscope located in the School of Biosciences has been specifically developed to perform multimodal correlative CARS, two -photon fluorescence (TPF) and second harmonic generation (SHG) microscopy for applications in cell biology.

With this system, we have developed a hyperspectral CARS modality including a quantitative image analysis method which distinguishes the composition of chemical components and retrieves their concentration and spatial distribution.

Resonant Four-Wave Mixing Imaging with gold nanoparticles

Gold nanoparticles (NPs) are ideal optical labels for biological applications owing to their biocompatibility and photostability, and much effort has been devoted recently to develop techniques capable of detecting gold NPs in cells and tissues with high contrast and sensitivity to the single-particle level.

By detecting the transient four-wave mixing from gold nanoparticles in resonance with their surface plasmon, we recently demonstrated a multiphoton imaging modality suited for cell microscopy. Resonant Four-wave mixing is measured free from background using an interferometric time-resolved heterodyne detection. Owing to the third order nonlinearity, we achieved a spatial resolution significantly surpassing the one-photon diffraction limit. With this technique, high-contrast photostable imaging of Golgi structures is demonstrated in HepG2 cells labeled with gold nanoparticles of 10nm and 5nm diameter.
