As part of my Modern Physics lab course, I conducted an experiment to measure the ratio of an electron’s charge to its mass (𝑒/𝑚) using a Helmholtz coil setup. The procedure involved accelerating electrons through a potential difference and observing their circular motion in a known magnetic field. By varying the current and measuring the corresponding radii of electron orbits, I was able to calculate 𝑒/𝑚 using the derived relationship between voltage, magnetic field, and orbital radius. After performing five independent trials and analyzing the data graphically, I obtained an average value of 1.735 x 1011 C/kg, with an impressively low error rate of 1.35% and a corresponding uncertainty. The result closely aligned with the accepted value, indicating both the reliability of the setup and the precision of the measurements.
Successfully completing this experiment was a pivotal moment in connecting my theoretical understanding of electromagnetism and classical physics with hands-on experimental techniques. It deepened my appreciation for the historical and conceptual significance of Thomson’s original work, and challenged me to engage critically with the methodology, uncertainty analysis, and data modeling involved in a modern replication. More importantly, this lab demonstrated the practical limitations and strengths of scientific measurement, how precise outcomes can still emerge despite imperfect instruments or human error. It also reinforced foundational concepts that are central to both classical and quantum physics, such as the Lorentz force, kinetic energy, and electron behavior in magnetic fields.
This experience has strengthened my confidence in experimental physics and reinforced my interest in pursuing research in areas involving charged particle dynamics, beam optics, and electromagnetic field control, topics that are crucial in both astronomy and applied optics. I plan to build on these skills by seeking out undergraduate research opportunities in experimental physics or optical instrumentation. More broadly, this lab gave me a concrete sense of how abstract theory is translated into measurable reality, something I will carry forward into more advanced coursework, lab work, and eventually, professional research.

In the fall of 2021, I ventured out into the western deserts of Oklahoma to attend the Okie-Tex Star Party. This annual event is organized by the Oklahoma City Astronomy Club, and it draws astronomy enthusiasts from around the country to Camp Billy Joe near Kenton, Oklahoma. Renowned for its exceptionally dark Bortle 1 rated skies, the location offers unparalleled stargazing and astrophotography opportunities.
Despite the emptiness of the surrounding region, there were more than enough things to do during all hours of the day. Daylight was used for attending lectures, research presentations, workshops, swap meets, or just socializing with fellow astronomers. At night, the camp glowed eerily red, as all other kinds of light were shut off, everything fell silent, and the observations began. I’ve never seen the Milky Way with such clarity.
This experience introduced me to a deeper level of observational astronomy than I had ever encountered before. I had the chance to interact with professional and amateur astronomers alike, ask questions, and learn about the practical tools and techniques used in the field.
The conversations I had during the day translated into guidance at night, as more experienced observers generously shared their expertise and even let me view distant galaxies, nebulae, and star clusters through their custom equipment. The Okie-Tex Star Party was more to me than just a skywatching event. It was a convergence of knowledge, mentorship, and scientific enthusiasm that helped me connect my academic curiosity with the broader community of astronomy.
Since then, I’ve carried this inspiration into my academic life, using what I learned to guide my coursework and research interests in physics and optics. I’ve maintained some of the connections I made at the event, staying in contact with mentors who have offered advice on instrumentation and graduate studies. The star party solidified my desire to pursue astronomy and optical physics not just as a subject of study, but as a community I want to contribute to.
It’s also motivated me to attend more conferences, seek out research opportunities, and eventually share my own work in settings like Okie-Tex, where passionate individuals gather to push the boundaries of what we can see and understand about our universe.

In spring 2025, I was awarded the Admiral William C. Bryson Endowed Scholarship by the University of Arkansas Department of Physics. This honor recognizes undergraduate physics majors with strong academic records and a dedication to astronomy, reflecting the legacy of Admiral Bryson, an engineer, naval officer, and amateur astronomer. With a GPA above 3.0 and a proven dedication to my astronomical studies, I was deeply grateful to be chosen for this distinction.
Receiving this scholarship affirmed my academic efforts and passion for astronomy, connecting me to Admiral Bryson’s interdisciplinary excellence while fostering a sense of belonging within the scientific community. It alleviated financial pressures and reinforced the significance of my contributions in coursework, research, and observation.
Motivated by this recognition, I am now pursuing deeper engagement with astrophysics and optics, seeking mentorship and internships in astronomical instrumentation. Moving forward, I aim to honor the scholarship’s spirit by bridging academic and amateur astronomy communities, advancing our collective understanding of the universe through both exploration and innovation.
