Development of new terahertz quasi-optical devices and strategies for new generations of specialised space telescopes and atmospheric monitoring satellites.

Optical receiver design for far-infrared wavelengths for the Herschel Space Observatory (HIFI instrument) and the Atacama Large Millimeter Array (ALMA).

Design and verification of instruments used in projects to observe the cosmic microwave background, including MBI, QUaD, and the Planck Surveyor Satellite.

Experiments to investigate the behaviour of water and aqueous solutions in the vicinity of the density anomaly, which in pure water at 1 atm pressure occurs close to 4 °C.

Electron impact ionisation and dissociation of molecules and clusters that are of interest to biophysics (radiation damage), atmospheric physics and other fields.

Study of the complex interplay of chemistry, dynamics and radiation balance in the upper atmosphere, with particular emphasis on the mesopause (80-100 km).

The design and development of terahertz imaging systems and resonant beam combining for non-invasive biomedical imaging.

High performance computing is used for the design and modelling of optics in the terahertz band with applications in astronomy, security, defence and medicine.

Near-infrared light is used for the interrogation of biological tissue, allowing non-invasive monitoring of biochemical processes.
