Type II migration of planets on eccentric orbits

Space Scientist

I’m a civil servant in NASA’s Meteoroid Environment Office, and my work involves a combination of data analysis, dynamical modeling, and software programming. I’m the current lead developer of the Meteoroid Engineering Model, a piece of software that simulates the meteoroid environment encountered by spacecraft. I also forecast meteor shower activity using numerical simulations of meteoroid streams and by fitting the activity profiles of past meteor showers. I sometimes study special environments; for example, I created an early model of the coma of Comet Siding Spring during its close encounter with Mars.
