My research lies at the boundary between the fields of astrophysics, planetary science, geophysics and geochemistry. I study the formation, structure and evolution of terrestrial and giant planets. In particular, I am to elucidate the history of Earth and how it became habitable. More...
I have been award the Pellas-Ryder award! Jointly awarded by the Meteoritical Society and the Planetary Division of the Geological Society of America, this award is conveyed for the best planetary science paper written by an undergraduate or graduate student and published during the previous year. The award recognizes my work on lunar origin which was published in Lock et al. (2018). See citation here.
Adler Planetarium in Chicago has developed a new show, 'Imagine the Moon', that 'explores how the Moon has inspired human creativity, learning, and exploration ever since we have looked to the sky'. This show features some amazing animations of our recently proposed Moon model, created with input from Sarah Stewart and myself.
Congratulations to my former Ph.D advisor, Sarah Stewart, for being selected as a MacArthur Fellow. This award is commonly known as the 'genius grant'.
We have proposed a new model for the origin of the Moon: that the Moon formed inside the vaporized Earth. Our model can explain various observations of Earth and the Moon for the first time. Learn more...
We have discovered a completely new type of astrophysical object that we have named synestias. These are fascinating objects that have the potential to revolutionize our understanding of how planets form and evolve. Intrigued? Learn more...
