Chemistry Student's Reflection on Geological Society of America Meeting

The student’s presentation focused on her research titled “Development and Adjustment of a Spectrophotometric Assay to Quantify Ammonia in Shallow Groundwater in Moldova.” Her work centers on creating and refining a reliable laboratory method to measure ammonia levels in groundwater—an important indicator of environmental quality and potential contamination. By improving the accuracy of this spectrophotometric assay, her research supports efforts to monitor water safety, understand pollutant behavior, and address environmental health concerns in the region.

Reflection by Ayanna Stewart • GSA Connects 2025

Attending and presenting at GSA Connects 2025 in San Antonio, Texas, marked a defining moment in my academic journey; a fitting culmination to my undergraduate years and an inspiring bridge to my graduate education. Engaging with scientists and researchers from across the country allowed me to share my work on soil and groundwater contamination, a project that represents the intersection of my interests in chemistry, environmental science, and public health. Presenting in both poster and oral formats not only sharpened my communication skills but also deepened my appreciation for the collaborative, interdisciplinary nature of scientific research. The experience reinforced how much I have grown as a researcher and how much potential there is to continue contributing meaningfully to this field.

I owe much of this progress to the mentorship of Dr. Ratan Dhar, whose unwavering support challenged me to think critically, take initiative, and expand beyond my comfort zone. Under his guidance, I gained hands-on experience investigating environmental contaminants and their chemical behaviors -- a perspective that allowed me to apply my background in chemistry to real-world environmental issues. I am equally grateful to the STEMCARE Program, where I first developed the curiosity and technical skills that define my research approach today.

Through the mentorship of Dr. Emmanuel Chang and Dr. Ruel Desamero, I learned not only the fundamentals of analytical chemistry but also the value of persistence and creativity in scientific inquiry. I also extend my heartfelt thanks to Provost Dr. Derrick Brazill for his support and for providing the research and travel funding that enabled me to share my work with the national scientific community.

This opportunity reaffirmed my commitment to pursuing a graduate degree in analytical chemistry with an environmental focus. I am eager to build on this foundation by exploring the chemical characterization of pollutants and their long-term effects on ecosystems and public health. As I move forward, I carry the lessons, mentorship, and inspiration from this journey with me, ready to contribute to research that supports a more sustainable and healthier world.
