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 for novel interdisciplinary visualizations. The work within this paper developed a physics-based method most similar to logistic regression to rank and classify transient of energetic material around Saturn (interchange injections). This created the first standardized comparison to several statistical surveys undertaken to understand the transport of mass around Saturn.

Are Saturn’s Interchange Injections Organized by Rotational Longitude?

Published in Journal of Geophysical Research: Space Physics, 2019

This work investigated if mass transport events most similar to Rayleigh-Taylor instabilities in Saturn’s space environment were related to ionospheric or upper atmopsheric conditions. To complete this work we undertook a large-scale data occurrence analyses to tease apart multiple dependencies.

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.
