Interchange Injections at Saturn: Statistical Survey of Energetic H+ Sudden Flux Intensifications
Published in Journal of Geophysical Research: Space Physics, 2018
Featured article in July 2018. Studying high‐energy particles around magnetized planets is essential to understanding processes behind mass transport in planetary systems…We present a computational method to identify and rank interchange injections using high‐energy particle fluxes from the Cassini mission to Saturn. These events have never been identified computationally, and the resulting database is now publically available…

Statistical study of the energetic proton environment at Titan’s orbit from the Cassini spacecraft
Published in Journal of Geophysical Research: Space Physics, 2018
A statistical study of the energetic proton environment at Titan's orbit as captured by the MIMI/LEMMS and MIMI/CHEMS instruments is performed…ion fluxes reveals a weak asymmetry in Saturn local time with the highest fluxes occurring in the premidnight sector of the magnetosphere…This model can be used to better understand the interaction of Titan with the magnetosphere and the energy deposition by energetic particles below the main ionospheric peak.

Are Saturn’s Interchange Injections Organized by Rotational Longitude?
Published in Journal of Geophysical Research: Space Physics, 2019
When estimating the rotation rate of Jupiter and Saturn scientists often use a periodic signal of radio emission…we analyze interchange's occurrence rate, as observed in particle data from the Cassini spacecraft, with respect to two longitude systems…We find that interchange occurrence shows only weak organization in these longitude systems as compared to organization by local time.

A Statistical Picture of Pitch Angles of Interchange Events at Saturn and Implications for Energization and Losses
Published:
Abstract: We utilize data from the CHEMS instrument to present a statistical review of pitch angles of interchange injections.
Multivariate Supervised Classification for Instabilities at Saturn: Comparison of Methods for Automated Event Detection in Magnetospheres
Published:
Shortened Abstract: In 2004 the Cassini mission arrived at Saturn. For the next 13 years the mission collected large amounts of data, resulting in a highly sampled magnetosphere of Saturn. Saturn is now the second most observed magnetosphere after that of Earth now allowing opportune applications of large scale statistical methods.
Jupiter with Jupyter: Lessons from Teaching Data Visualization and Statistics in Geosciences
Published:
Abstract: With the advent of post-bachelorette opportunities within data analysis and sciences, there is a clear need for students to understand the basics of data science. Data science knowledge gain includes core student understanding in statistics, programming, and data visualization.
