Brooke Nicole Newell

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.

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 glasses with Bayesian inference and...

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.
