Impact is a fundamental solar system process: it builds planets from dust, it shapes planetary surfaces, it causes mass extinction and it threatens the survival of humankind. My research explores the many consequences of impacts in the solar system through the development and application of numerical impact models.

Research Interests

My interests include all aspects of impact cratering and other, related violent geologic processes. 

I develop and use numerical models to study impact processes, their consequences on Earth and in our Solar System, and related large, rapid, violent geologic processes, such as large rock avalanches.

For more information on my research, please visit my research pages.

Cratering in the News

There are ~185 known impact craters on Earth, and more are found each year.  Some recent media articles I have been involved in:
