I am a Master's student at the University of South Florida, Tampa majoring in Geology with a focus in geochemistry. After earning my Bachelor's degree in Marine Biology, I chose to explore the interdisciplinary field of biogeochemistry to gain expertise in analytical techniques within environmental sciences. My research interests include marine ecology, conservation science, and applied biogeochemistry.

My thesis research uses stable isotope analysis (δ13C and δ15N) to study the trophic dynamics of aquatic environments. My work investigated the transition of captive-reared largemouth bass (Micropterus salmoides) to released environments as detected through isotopic compositon of non-lethal biopsy tissue samples. This study addresses questions related to the different isotopic assimilation observed across different tissues and species and the applications of such biogeochemical methods to population monitoring and fisheries management.
In my undergraduate research, I designed a field survey study to monitor changes in the population dynamics of upside-down jellyfish (Cassiopea andromeda) in response to different environmental variables in mangrove habitats. I then collaborated to implement an experimental study to determine the mechanism for Cassiopea water movement as benthic organisms (https://doi.org/10.1038/s41598-023-30101-4).

As a student and researcher in science, I consider it a vital part of my responsibility to be active within my community by promoting education and understanding. For me, this applies to both environmental and socio-political advocacy. As such, I am involved with multiple on-campus organizations and off-campus community engagement positions focused on educational accessibility and community support. Academically, I specialize in tutoring science, math, reading, and writing for grades 1-12, college courses in science and writing, and developing individualized lessons for students with learning disabilities.
My volunteering allows me to coordinate with programs which focus on providing free tutoring to students in underprivileged positions where additional education sources can be limited. It also allows me to facilitate an interest in science and education in the younger generation of students.

My personal interests include painting and other artistic styles, amateur photography, and martial arts. I currently co-train in karate (shodan) and aikido (gokkyu). I love to use art as a way to connect with people and sharing my fascination with the natural world.

I successfully defended my thesis on September 25, 2025 and will be graduating in December 2025. With this, I'm excited to begin transitioning towards the next step in my career.
