High proportions of autistic children suffer from gastrointestinal (GI) disorders, implying a link between autism and abnormalities in gut microbial functions. Increasing evidence from recent high-throughput sequencing analyses indicates that disturbances in composition and diversity of gut microbiome are associated with various disease conditions. However, microbiome-level studies on autism are limited and mostly focused on pathogenic bacteria. Therefore, here we aimed to define systemic changes in gut microbiome associated with autism and autism-related GI problems. We recruited 20 neurotypical and 20 autistic children accompanied by a survey of both autistic severity and GI symptoms. By pyrosequencing the V2/V3 regions in bacterial 16S rDNA from fecal DNA samples, we compared gut microbiomes of GI symptom-free neurotypical children with those of autistic children mostly presenting GI symptoms. Unexpectedly, the presence of autistic symptoms, rather than the severity of GI symptoms, was associated with less diverse gut microbiomes. Further, rigorous statistical tests with multiple testing corrections showed significantly lower abundances of the genera Prevotella, Coprococcus, and unclassified Veillonellaceae in autistic samples. These are intriguingly versatile carbohydrate-degrading and/or fermenting bacteria, suggesting a potential influence of unusual diet patterns observed in autistic children. However, multivariate analyses showed that autism-related changes in both overall diversity and individual genus abundances were correlated with the presence of autistic symptoms but not with their diet patterns. Taken together, autism and accompanying GI symptoms were characterized by distinct and less diverse gut microbial compositions with lower levels of Prevotella, Coprococcus, and unclassified Veillonellaceae.

In early 2026, the NASA Discovery Program will fall into orbit with a metal asteroid named Psyche. Through discovery and interaction, this exploration will give us insight into an asteroid that we cannot see or interpret. From a certain view, you can look at how this mission mimics that discovery with experimentation of our own senses. As a part of a team of eight seniors, we were tasked to help develop a mobile application that reflects the Psyche mission and shows the future of the project ten years from now. Since this is also a government funded project, it is pertinent to adhere to the ADA compliance guidelines required to make digital applications accessible to the larger public. As a designer, I wanted to push this concept further to showcase that accessibility is not something that should be stereotyped or discouraged from a design perspective. Each person that interacts with the application will have a different experience but it is this collaboration between the object and it's audience that creates this sense of discovery. Taking the mission's core values one step further, this application was designed and explored to uphold the foundations of what Universal Design is about. It is about connecting interested parties to the material they are looking for without unrealistic access that is dependent on ability.

Capstone project, I began developing an animated series called Legends of Gaia. The show follows a small group of people of mixed ages and backgrounds, as they travel across the world trying to stop the Galliean Empire, a technologically booming western power that has begun fighting a war for world domination. The purpose of this paper is to better explain the origins and inspirations of the mythology of my series, as well as the major two supernatural characters of my series, and the general geography (both physical and metaphysical) of the series. When first developing this series, I looked into the works of Joseph Campbell, as he wrote the book(s) on mythology in many ways. His most famous writings are probably the Hero's Journey and the Monomyth, the basic outline of the journey that most heroes go through, from the call ordinary world, to the call of the adventure, all the way to the hero returning (Campbell 211). Many classic examples of story telling follow the pattern Campbell outlined, and my work is no exception. However, I did not want my series to be a beat for beat retread of the Hero's Journey, and so some parts, such as the Refusal of the Call, when the hero rejects the adventure and befalls a tragedy, were skipped, while others, such as the resurrection, were realized in different ways. Using the Resurrection as an example, in my series the main female character, Diana is reborn twice throughout the series. Once in the final battle with the main villain into her true, goddess form, and the other when her battles are over, and she is reborn in her mortal form permanently.

De Oriendo is a project devoted to a better understanding of the word "original" as it pertains to musical composition. It began as a way for me to try to tackle a twofold fascination that has been with me for the duration of my time at ASU, though I have not always been aware of it. The first half of this fascination is an enduring interest in tracing borrowed material used by composers and other artists throughout history. It seems that almost every research project I have undertaken in the last four years has had something to do with this concept. Scholars like Winton Dean, J. Peter Burkholder, and Sigmund Spaeth have spent parts of their careers charting out the genealogy of historical compositions, uncovering reused melodies and harmonic progressions in the process; the cases of it are countless, even among the most identifiable composers and songwriters. Since there is scholarship clearly demonstrating secondhand ideas in music, it becomes problematic to assume that the word "original" simply describes something completely new, that is, something that does not use material heard or seen before. The second half is more of a personal ambition: I thought that if I truly knew what composers and critics meant when they labeled a piece or an artist as original, then I could somehow find a way to achieve this distinction in my own attempts at composition and avoid that uninteresting, derivative sound I have always feared.

Fumonisins are fungal metabolites found in corn and cereals. Fumonisins pose health risks, including suspected carcinogenicity, yet their mechanism of toxicity remains unclear. While modifications in the human gut microbiome can impact host health, the effects of fumonisins on the microbiome are not well understood. Thus, our study aimed to assess a possible dose-response relationship between fumonisin B1 (FB1) and the gut microbiome. We utilized in vitro anaerobic bioreactors with media simulating most of the nutrients in the human large intestine, inoculated them with fecal samples from 19 healthy adults and treated them with FB1 at concentrations of 0, 10, 100, and 1000 ppb. Analyses of bioreactor headspace revealed declining methane production over time, possibly influenced by the addition of dimethyl sulfoxide (DMSO). Significant differences in acetic acid production were observed in 10 ppb reactor (Day 2) and 100 ppb reactor (Day 8) when compared to 0 ppb control. Microbiome analysis showed minimal shifts in microbial relative abundances during FB1 treatment, except for Desulfovibrio desulfuricans C at Day 8 when compared between 0 ppb and 10 ppb as well as 10 ppb and 1000 ppb at Day 16. Alpha diversity analyses indicated significant differences in observed features within bioreactors of different treatments, with some variation in Faith’s Phylogenetic Diversity between the 0 ppb and 10 ppb bioreactors. Beta diversity analyses, however, revealed no significant differences between bioreactors. Overall, our findings suggest no clear dose-response relationship between FB1 treatment and gut microbiome composition/functions. The presence of DMSO may have obscured potential effects. This research will help contribute to our understanding of mycotoxicity influence on the human gut microbiome.
