Science and Natural Philosophy in the Poetry of Heinrich von Meissen (Frauenlob)
… geological science, chemistry, cosmology, and observational astronomy. The presence and recognition of these additional meanings gives important insight into both Frauenlob’s materialist worldview as well as into the intellectual expertise expected of his intended audience.

Courting Serendipity: The Search for Transient Radio Signals
The transient radio sky remains a frontier of observational astronomy, not for lack of scientific promise, but for practical obstacles: terrestrial radio frequency interference (RFI) and limited computing power. Today, a confluence of new RFI mitigation techniques and computing power makes a …

Mathematical and Deep Learning Methods in High-Energy Physics: From Temporal Variability in M82 ULXs to Spatial Features in Planck Maps
Modern Astronomy gathers data from a plethora of instruments from the ground and from space, spanning the entire electromagnetic spectrum and even some non-electromagnetic carriers of information, such as neutrinos and gravitational waves. The quality and quantity of data is rapidly increasing over …

The Observational Diversity of sub-Neptunes
This dissertation focuses on characterizing the atmospheres of sub-Neptunes (planets larger than Earth but smaller than Neptune), the most common exoplanets in the galaxy. With no examples in our own Solar System, we are limited to the data quality of remote-sensing capabilities. I aim to unveil …
