Prachi is a graduate research assistant at School of Earth and Space Exploration, Arizona State University. Her research interest involves investigation of the structure, dynamics and evolution of the Earth’s lowermost mantle using numerical modelling. She is a part of the GD blog team as an editor as well as an illustrator.

Two phase or not two phase

Two phase or not two phase

In this week’s blog Shi Joyce Sim from Georgia Institute of Technology shares the underlying science behind two-phase flow dynamics.   A talk at the Lunar and Planetary Science Conference in March got me thinking. Basically, the presenter described how boundary layers grow over time, a phenomenon that cannot be captured using one dimensional models and necessitates modeling in higher dimensi ...[Read More]

Regional viscosity variations in Earth’s mantle

Regional viscosity variations in Earth’s mantle

For understanding the dynamics and evolution of the Earth’s mantle, knowledge of mantle’s viscosity structure is very important. In this week’s blog, Kenneth Gourley from University of Arizona discusses the variation of viscosity structure in Earth’s mantle in regional scale.   In order to understand the dynamics and evolution of the Earth’s mantle, geodynamicists model mantle fl ...[Read More]

Slow Evolution of Europa’s Interior

Slow Evolution of Europa’s Interior

“Europa may be one of the most promising places in our solar system to find present-day environments suitable for some form of life beyond Earth.” This week in News & Views, Kevin Trinh, a PhD student at Arizona State University, discusses how his recent works on Jupiter’s moon Europa can enlighten us about the evolution of Europa’s interior. One of the most promising p ...[Read More]

Going to the mountains is going home

Going to the mountains is going home

Geoscientists explore the nature from a different perspective than the commoners. In this week’s blog, Stephanie Sparks from Arizona State University shares her story how her passion for mountains gradually became her profession. Her journey through different regions in Himalaya leads her to understand the exhumation rate and the underlying geodynamic processes behind the formation of world’s high ...[Read More]
