Salma Ahmed

Advisor: Burkhard Militzer I use density function theory and ab-initio molecular dynamics to study matter in extreme conditions, which include the conditions of planet interiors. My latest project was to study high pressure electrides, in which valence electrons of atoms instead localize in the interstitial sites of the material. I received my bachelor's and master's degrees in chemistry at San Francisco State University, where my previous research was simulating superionic metal halides as a proxy for Li-ion batteries. I have also been an NSF-GRFP Fellow since 2023.

Colin Baciocco

Advisor: Madison Douglas

I am a geomorphologist who studies how the hydroclimate and landscapes interact, particularly in the Arctic. My work involves an interplay between field observations, lab analysis of materials collected in the field, and implementing those observations with geomorphological theory and numerical / analytical modeling. I also develop methods for using very large remote sensing datasets to answer geomorphological questions.

Kyla De Villa

Advisor: Burkhard Militzer

I use computer simulations (ab initio and machine learning) to study the properties of materials under the extreme conditions of planetary interiors. By calculating equations of state and transport properties of planetary ices, I then perform magnetohydrodynamic (MHD) simulations of ice giant planets to infer the role of radially varying material properties on magnetic field morphologies and heat flows. Similarly, using atomistic shock simulation techniques, I study giant impact induced shock synthesis of prebiotic...

Brooke Nicole Newell

Advisor: Ben Gilbert

I study the spatiotemporal dynamics of paramagnetic species in Earth systems, with a focus on the rhizosphere and post-wildfire landscapes. I develop new methods to observe biogeochemical processes in situ within plant–soil systems. My work combines quantum sensing with nitrogen-vacancy center nanodiamonds, controlled laboratory and microfluidic experiments, and geochemical and geomorphological frameworks to track reactive species such as rare earth elements and environmentally persistent free radicals.

Sarah Shi

Advisor: Penny Wieser I am a petrologist working at the intersection of geochemistry and machine learning. I am fascinated by records of Earth's magmatism and volcanism stored in minerals and melt inclusions, from magma storage and transport prior to eruption to the timescales of magmatic processes. A central thread in my research is making these records more accessible and reproducible. I develop open-source tools like PyIRoGlass for quantifying volatiles in melt inclusions and...

Advisor: Raymond Jeanloz

I use diamond anvil cell experiments to study the thermal properties of planetary materials under extreme pressure-temperature conditions representative of deep planetary interiors. I'm currently considering when Earth's solid inner core nucleated, how Earth’s magnetic field might have persisted for billions of years before its nucleation, and the resulting impact on global planetary heat flow.
