Field and Laboratory Ecologist
As part of my N.O.A.A. Earnest F. Hollings scholarship, I will be conducting an internship under the guidance of Dr. Mark Ladd (N.O.A.A. SEFSC) and Dr. Donald Behringer (UF) to develop hands-on, practical experience in research. The project, titled “Honey I’m home: the relationship between habitat characteristics and intensity of Carcinonemertes conanobrieni on the Caribbean spiny lobster, Panulirus argus“, will combine landscape and parasite ecology in a collaborative manner. While assisting Master’s student Natalie Stephens in Dr. Antonio Baeza’s lab (Clemson) with her project investigating the impact of C. conanobrieni on P. argus fecundity and reproductive health, I will collect field data regarding sampled lobster dens and surrounding habitat characteristics. This data will be assessed with C. conanobrieni intensity among and across individuals to investigate the potential relationship between certain habitat characteristics (eg. dominate structural organism, substratum characteristics, aggregation of female P. argus, etc.) and intensity of C. conanobrieni infection.
Volunteer Research Assistant
While studying away at the University of the Virgin Islands, I assisted graduate student Matt Souza with various projects. His work focuses on the range of invasive seagrass, Halophila stipulacea, and how it effects local invertebrate populations. My contributions include radial and line transect surveys, invertebrate collection and identification, and experimental design trials for conch predation studies as an AAUS scientific diver. My invertebrate identification skills improved tremendously while assisting Matt, and my understanding of community interactions among seagrass beds is continuing to expand.
Gas Chromatography Analyst
Part-time employment in Dr. Nick Peng’s lab at U of SC involved analyzing gas chromatography samples of various marine fungi species. The overarching goal was to investigate the output of greenhouse gas (N2O-, CO2, CH4) emission in fungi samples. The data collected provided background information of the marine fungi species to be developed on in future studies. My contributions also contributed to a manuscript recently submitted to Frontiers in Marine Science; Lazo-Murphy, B., Larson, S., Staines, S., Bruck, H., McHenry, J., Bourbonnais, A., & Peng, X. (submitted 15 Nov 2022, under review). Nitrous oxide production and isotopologue composition by fungi isolated from salt marsh sediments. Frontiers in Marine Science. Other skills learned included inoculation of cultures, inputting data into MATLAB, and GC machine maintenance.
Limnology Independent Project
Designed, conducted, and analyzed results of absorption data of phytoplankton community samples. The samples were the same used in the Phytoplankton Community Experiment (see below). A UV-Spectrophotometer was used to measure absorption of phytoplankton communities in different light treatments and phosphorus levels. The goal was to assess competition among phytoplankton groups in the specified treatments over a 54 day time span using absorption data as well as species identification from PhD candidate Jake Swanson. David Abdulrahman, a senior undergraduate at UofSC, was also a big help throughout the project by contributing to the collection and maintenance of phytoplankton in microcosms. I found that overall community absorption can act as an indicator of community composition shifts towards cyanobacteria or cryptophyte dominance when acclimated to certain light and phosphorus conditions. This was my first experience creating my own graphs and analyzing my own data in R, as well as creating and presenting a poster. It was a valuable learning experience, and the mentorship provided by Dr. Dudycha, Dr. Richardson, Dr. Pinckney, and Jake Swanson was incredibly helpful. I presented this project as a poster at the Ecological Society of America conference in Montreal, Canada in August of 2022. Travel to ESA was funded by the Magellan Voyager Grant, UofSC Honors College Conference Travel Grant, and a contribution by the UofSC Biological Sciences Department.

Phytoplankton Community Experiment
I assisted PhD candidate Jake Swanson with his project focused on phytoplankton community ecology. Water samples from local SC lakes were introduced to light (full, blue, red, green) and phosphorus (high or low) treatments. I assisted with the initial water collection, occasional sampling over the 54 day experiment, and preparing materials for the project.
Fall 2020 – Summer 2021
As a part-time position during school and full-time during the summer, I worked as a lab technician in Dr. Jeffry Dudycha’s lab at U of SC. My general duties included maintenance of water flea populations, filtering lake water, cultivating algae, sterilizing equipment, and various lab maintenance responsibilities.
