In particular I have been working with Professor Frebel on the analysis of metal-poor stars from my second year until now. Using this technique, I created a project involving the chemical evolution of phosphorus. I was responsible for analyzing the high-resolution UV spectra of several metal-poor stars from the Hubble archive to determine star properties such as metallicity, temperature, and surface gravity by measuring the equivalent width of the Fe I and Fe II lines. I was also responsible for measuring the abundance of phosphorus in stars using its UV doublet using the spectral synthesis method. The result shows how the abundance of phosphorus in the universe evolves over time, and the project results in two publications. As of now, I am preparing and writing a paper that involves using this same technique to measure the abundance of neutron-captured elements in an r-process star. The preliminary result suggests that the star exhibits the r-process signature. The result of this project will add further data to the formation process of these little-known stars. From my extensive experience in astronomical research, I believe the skills I acquired during college will help me succeed in astronomy. I am hopeful about going to graduate school and pursuing a PhD in astronomy. It's the right path for me as I enjoy observing, researching astronomy and teaching
