What I work on

Research

I study how small bodies deliver material to Earth, connecting what telescopic surveys see in space, what wide-field camera networks catch coming in, and what we analyze in the lab afterwards. Across all of it, what reaches the ground is only a filtered sample of what actually hits Earth.

Finding meteor showers that aren't there

How you tell a real meteoroid family from a coincidence — background models, cumulative similarity, and the 5.3σ detection of a new near-Sun stream. With four interactive tools built on the real data.

Perihelion filtering & the meteorite record

Why meteorite collections are a thermally and atmospherically filtered subset of what actually hits Earth, and where the carbonaceous chondrites went.

Small-body dynamics

Cometary ↔ asteroidal reservoir mixing

Most “comet-like” fireballs come from asteroidal material, not comets: long-term integrations show the near-Earth Jupiter-family population is dominated by asteroidal interlopers.

Sensor fusion & radar meteorite detection

Turning the NEXRAD weather-radar network into an automatic meteorite-fall detector, and working toward fusing radar, optical & infrasound to close the 10–100 m “decametric gap.”

Meteorite recovery & fireball networks

Fireball-network science across the full chain, from astrometry and orbits to drone- and ML-assisted recovery of fresh, orbit-bearing meteorites.

Tools & demos
