Research Interests

Objectives  

The overarching theme for my research is the  origin and evolution of small bodies in the solar system and their delivery/impact on Earth.In broad form, the long-term objective of my research program is to better understand the beginnings of the solar system by examining its most primitive objects, namely comets and asteroids, through study of their debris in the form of meteoroids and how these objects interacting with the Earth have affected our origins. My research program builds on my existing work and is composed of research projects linked together in specific research themes which address this global objective.

      The four research themes in my program and their objectives include:

  1. Meteoroid structure: Using the interaction of meteoroids with the atmosphere, (producing the light, heat and sound phenomena collectively termed a meteor), measurement of the physical structure and composition of small meteoroids is performed and related to the makeup of their parent body populations.
  2. Meteoroid impact effects on planetary atmospheres and surfaces: The objective of this theme is to measure the flux of impactors (mainly in the tens of meter size range and smaller), their velocity distribution and the effects of such impacts on planetary bodies.
  3. Meteoroid Stream Evolution and Origins (Orbital Dynamics): To identify meteoroids with specific parent bodies and relate their characteristics directly to particular small bodies. A related objective in this theme is to identify possible interstellar meteoroids and relate specific meteoroids to progenitor planetary systems, thus directly "sampling" material from other stellar systems.
  4. Meteorite Origins and Cosmochemistry: Collect samples in the form of meteorites which are instrumentally recorded to fall, reconstruct  pre-atmospheric orbits and determine the physical nature (strength, size, shape) of the pre-impact body through its ablation behaviour.
