Research Interests

Research interests include:
- Spectroscopic and photometric analyses of stars, including a range of pulsating stars: Cepheid variables; R Coronae Borealis stars; RV Tauri stars; post-AGB stars; Extreme He and other rapidly pulsating stars.
- Abundances, particularly s-process elements, in late type stars.
- Astronomical instrumentation developments for Mt John Observatory and the Southern African Large Telescope: Adaptive Optics and SCIDAR measurements at Mt John; High Resolution Spectrograph (SALT HRS) design for SALT.
