  abstract     = {{One of the biggest questions people ask astronomers is whether life exists elsewhere in the universe. Unfortunately, we don’t yet have an answer. Instead, progress towards an answer comes in small, careful steps. This thesis is one of those steps.<br/><br/>My research has focused on the atmospheres of "ultra-hot Jupiters": planets the size of Jupiter that orbit so close to their stars they are heated to thousands of degrees. At those extremes, their atmospheres behave almost like water in a boiling pot, except it isn’t just water that evaporates, it's the atmosphere.<br/><br/>These worlds may sound exotic, but paradoxically they are the easiest planets for us to observe. When they pass in front of their stars, starlight filters through their atmospheres and into our telescopes. By applying a technique called cross-correlation, I can detect the \say{fingerprints} of gases and even trace winds racing around them at thousands of kilometres per hour.<br/><br/>A key part of my work has been to make this technique more reliable, ensuring that the signals we claim are genuine and not just noise. In doing so, I’ve shown that even smaller telescopes, ones often overlooked for this kind of work, can still reveal remarkable detail. That matters, because it means more observatories around the world can join in, and more data can be brought to bear the study of exoplanet atmospheres.<br/><br/>Ultra-hot Jupiters orbit their stars on timescales of just a few Earth days, making their transits predictable and easy to observe with high precision since they occur frequently. Each observation builds on the last, steadily improving our ability to interpret atmospheric signals. By studying these extreme worlds, we refine the tools needed to probe smaller, cooler planets, ultimately bringing us closer to the long-term goal of identifying an "Earth-twin".<br/><br/>}},
