Cosmochemist

Kelly Miller, PhD

Research


My diverse research interests center around CHNOPS chemistry in the solar system, including the origins and incorporation of these bio-essential elements into planetary bodies, their subsequent evolution, and their implications for habitability of planetary environments. 

 

Geochemical and Cosmochemical Modeling

I use thermodynamic analyses and chemical mixing models to investigate the evolution of chemical systems due to environmental parameters such as temperature, redox conditions, and pressure.


Mass Spectrometry Data Analysis

I am one of the lead data analysts for the Cassini Ion Neutral Mass Spectrometer, and have experience with data processing, including application of calibrations and removal of instrumental effects. I also do spectral deconvolution and modeling of adsorption effects.


Experimental Simulation of Icy Satellite Interiors

Project beginning mid-March 2019!

I will be working with Dr. Dionysis Foustoukos, Dr. George Cody, and Dr. Conel Alexander to experimentally investigate volatilization of complex chondritic organics under conditions relevant to the interiors of icy satellites.


Meteorite Sample Analysis

I study the mineralogy and petrology of chondritic meteorite samples to understand the pre-accretionary and post-accretionary environments that they record, especially with regards to volatile oxygen and sulfur chemistry. I have experience with electron microprobe analysis, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), and secondary ion mass spectrometry (SIMS) of oxygen isotopes.
