Cavendish Astrophysics

Areas of interest:
21-cm cosmology
Radio instrumentation


I am interested in the study of the early epochs of the Universe via observations of the 21-cm line. I am also interested in developing novel sensors and instrumentation for radio astrophysics, space technology and communications. 

Areas of interest: 21 cm cosmology; radio instrumentation; electromagnetic modelling; telescope calibration; antenna/array design; low noise receivers; synergies between instrumentation for Astrophysics and ultra fast digital communications and EM metrology.

Research group: Cavendish Radio Cosmology
