Research Experience:  
Sydney has completed a non-empirical study regarding the role of religion in medicine, as well as two empirical studies: the study at hand, and a research experiment that tested the probable connection between nature-connectedness and exposure to outdoor activities, as well as possible affects it may have on stress levels and environmental awareness. Sydney has also volunteered as a participant in the COVID-19 data and awareness ongoing study conducted by The Ohio State University, and as an ACT tutor for a senior-level high-school student. 

Presentation Experience: 
Sydney presented at the Capital University Symposium in 2019 and presented virtually for the 2020 National Association of Biology Teachers (NABT) Biology Poster Session with co-author Alysa Durbin. In addition, Sydney has presented virtually as both a competitor and a finalist in preparation for final judging at the upcoming American Association for the Advancement of Science (AAAS) 2021 Annual Meeting to be held in February 2021.

Significance of Research:       
Gluten is a protein complex that appears in wheat, barely, and rye, and even in foods that do not normally contain these grains. Those suffering from an intolerance to gluten, especially individuals that face Celiac disease, are careful to avoid gluten contamination in food products. It is necessary for afflicted individuals to know whether or not advertised gluten-free products contain the correct levels of gluten. The current study was designed to determine the reliability of gluten-free food labels in the consumer marketplace. Samples of gluten-free foods were collected from various locations in central Ohio, including restaurants, grocery stores, and health-food stores. A total of 222 samples were analyzed using a Nima Gluten Sensor (antibody-based colorimetric assay) to determine if gluten content was <20 ppm, the maximum allowed by US law for a product labeled gluten-free. Of the samples tested, 98 were certified as gluten-free (<10 ppm) by the Gluten-Free Certification Organization (GFCO); only 13 of these (13.3% of samples) were found to exceed 20 ppm of gluten. By comparison, 115 samples were labeled gluten-free on the packaging but did not contain certification; of these, 33 (28.7%) were found to contain more gluten than allowed by law. While results reveal that certified gluten-free products may be more trusted in their claim of being gluten-free, contamination can still occur for those who receive an inflammatory response by gluten grains. It is imperative to test the reliability of the gluten-free label to protect the health of individuals with intolerance to gluten.

Uniqueness of Research: 
Regulation on the gluten-free claim was recently established (FDA 2013), so data collected from this project adds to the scarcity of prior studies. This study aimed to support the protection of the health of all individuals at a dietary disadvantage; a basic principle for students pursuing careers in health and medicine.
