By determining which ice sheets melted to create a colossal increase in sea levels 14,500 years ago, scientists hope to enable better predictions of how current ice melting will affect levels around the world.

Biography
My research group explores global-scale geodynamical problems across many time scales. This includes solid Earth and ocean tides (acting on hours to years), the deformation of the Earth due to the melting of large Pleistocene ice sheets (years to tens of thousands of years), and mantle convection, the process that drives plate tectonics (millions to billions of years). The theme of all of this work is to understand how we can coherently characterize the Earth's behavior across these vastly different time scales and learn fundamental things about our planet.
Recent News
In a recent study published in Science Advances, DEEPS PhD candidate Manar Al Asad and Assistant Professor Harriet Lau demonstrate that Earth's early tectonic activity was likely very different from what we see today. They propose a 'sluggish-lid' mode, where the Earth's outer layer moved slowly and was partially disconnected from the mantle. The new model addresses previous challenges in understanding Earth's thermal history and tectonic evolution, offering new insights into how Earth's magnetic field is maintained throughout most of Earth's history.
