My research explores the final chapters of stellar life by focusing on white dwarfs—the dense, cooling embers left behind by stars like our Sun. I use a technique called asteroseismology, which measures the subtle, rhythmic pulsations of these stars, to probe their internal structures and determine their fundamental properties. To do this, I synthesize massive datasets from space- and ground-based surveys like TESS, Gaia, and SDSS, developing custom Python pipelines to find these faint stellar heartbeats. A key part of my work also involves improving the quality of astronomical data itself, ensuring that we can confidently build large, reliable catalogs of these fascinating objects for the entire community to use.
