Research

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
• EURONEAR project (European Near Earth Asteroid Research)
