Research

I am a Research Fellow at Armagh Observatory. A lot of my research consists of theoretical (computational) studies in solar system dynamics.
Interests include:

• regions beyond Neptune as the sources of comets and Centaurs
• formation, dynamical evolution and structure of meteor streams; meteor shower predictions (e.g. Leonids, Taurids); interplanetary dust complex
• near-Earth objects (NEOs - comets or asteroids on orbits that can come near the Earth), impact hazard, NEO observational surveys, orbit determination

My publications
Review of (Leonid) dust trail theories - how to predict meteor storms
The EURONEAR project (European Near Earth Asteroids Research)
Armagh solar system research topics
Sungrazers

Impact hazard:
NEO golf (computer experiment on asteroid deflection)
Armagh Observatory impact hazard page
Current positions of known asteroids in near-Earth space
Apophis
Minor Planet Center's NEO Page
Spaceguard UK and the Spaceguard Centre
Australian Spaceguard Survey (Michael Paine)

History

• born in Edinburgh (1966)
• studied maths at Cambridge University (1984-1988)
• in Oxford University's Department of Astrophysics (1988-1992)
  D.Phil. thesis `The Taurid meteoroid complex'
  `I was therefore entered at Oxford and have been properly idle ever since.' (Jane Austen, Sense and Sensibility, Chapter 19)
• did M.Sc. at The University of Edinburgh's Department of Artificial Intelligence (1992-1993)
• worked with AANEAS (the Anglo-Australian Near-Earth Asteroid Survey) at the Anglo-Australian Observatory (1993-1995)
• at Japan's National Astronomical Observatory (1996-1997); sometimes visited Tokyo University's Kiso Observatory
• in the Space Systems Section of the Kashima branch of the Communications Research Laboratory (1997-1998)
• at Armagh Observatory (1998 July - present)
• co-star in Hollywood movie Armageddon
• often visiting the Bisei Spaceguard Center at the invitation of the Japan Spaceguard Association (2000-2004)
