Erica Faucher, from Milford, New Hampshire, is majoring in biomedical sciences: medical microbiology at the University of New Hampshire. Erica presented her research on gut microbiome sampling methods at UNH’s Undergraduate Research Conference (URC).
Tell us about your research in as non-technical language as possible.
Erica Faucher: The human gut microbiome is made up of different types of bacteria that play an important role in human health, and these bacteria are studied using stool samples.
The purpose of this project was to compare two different stool sampling methods: bulk stool sample collection (the gold standard) and stool collection cards (FTA cards). This research is important because using FTA cards is easier for participants, and the cards can be stored at room temperature and mailed to researchers.
This method would make participation in microbiome research easier, especially for people living in remote areas. To determine if the two methods produce similar data, seven stool samples were collected from volunteers using both sampling methods, and bacterial abundances are being compared. If the results are similar, it would make microbiome research more inclusive.
What challenge does your research seek to address?
Erica: My research compared the FTA card method against the bulk stool sampling method in terms of bacterial abundance and diversity. FTA cards are cheaper, easier to use and don’t require freezing or ice. They can also be mailed, meaning researchers don’t have to travel to collect samples. This is important because it allows researchers to reach more remote populations and promotes inclusivity in gut microbiome research.
Your work elevates research supported by the NH Agricultural Experiment Station. How will your work benefit people, communities and/or the natural environment in New Hampshire?
Erica: Using FTA cards instead of bulk samples allows researchers to reach underserved populations, such as rural or remote communities in New Hampshire. It makes gut microbiome research more inclusive and helps us better understand how different factors—like culture, lifestyle, and eating habits—affect the gut microbiome across different groups.
What are you learning as a result of your experience?
Erica: I have learned many new skills, including conducting literature searches, presenting research and improving communication skills. I gained a deeper understanding of the gut microbiome and the bacteria that are natural to the human body.
Who are you working with? (Faculty, grad students, other undergrads)
Erica: The people involved with my project were Brandy Moser, Yobanna Taylor, Erin MacDonald, Lawrence Gordon, Joseph Sevigny, Kelley Thomas and my advisor, Dr. Maria Carlota Dao.
What should prospective students know about UNH?
Erica: Students should know that UNH is a place where diverse opinions and backgrounds are encouraged. UNH is a great place for making connections and building research skills, and there are so many resources here to support student success.
What do you love most about UNH?
Erica: I love all the amazing people I have met and worked with, and how supportive everyone is. It’s a very positive place to learn, and I am very glad I chose this school.
