Fountain, Sadaf Azadehfar

Theses and Dissertations

This thesis investigates the intersections of water, power, identity, and architecture through the lens of colonial and postcolonial landscapes, focusing particularly on Persian gardens and fountain sculptures. Drawing on historical, cultural, and symbolic frameworks, the study explores how water systems embody both practical and spiritual roles, positioning water as a force of control, resistance, and regeneration. Central to this work are analyses of arches and garden designs, which serve as architectural metaphors for cosmic harmony, community gathering, and contested space. Through a combination of visual analysis, historical research, and personal artistic practice—including ceramic sculptures and multimedia installations—this thesis traces the …

Kinasefusiondb: An Integrative Knowledge Of Kinase Fusion Proteins In Multi-Scales, Himansu Kumar, Zikang Chen, Abayomi Adegunlehin, Loren Trowbridge, Leonardo Aguilar, Pora Kim

Faculty, Staff and Student Publications

Kinase fusion genes were the most targeted fusion gene group among multiple major cellular gene groups. Kinase inhibitors disrupt aberrant signaling cascades and inhibit tumor progression, yet the specific mechanisms of action of the U.S. Food and Drug Administration (FDA)-approved inhibitors in the context of kinase fusion oncoproteins remain largely unknown. This gap limits our ability to develop personalized therapies and next-generation kinase inhibitors. To address this, we developed a novel in silico pipeline for predicting 3D structures of kinase fusion proteins and performing structure-based virtual screening. This approach enables large-scale structural annotation and drug screening across pan-cancer kinase fusions. …

Development Of Small-Molecule Inhibitors For Bacteroides, Naegleria, And Toxoplasma Microorganisms And Synthesis Of N-Heterocycles From Thiolated Ene-Ynes And Azodicarboxylates, Samuel Kwain

All Dissertations

Humans and microorganisms are intricately interconnected, with microbes constituting an essential component of human biology and ecology. This interdependence necessitates a delicate balance between leveraging beneficial microbes and mitigating the impact of harmful ones. The human gut microbiome, home to trillions of microorganisms, predominantly comprises commensal species that support health. However, dysbiosis within this ecosystem has been linked to serious diseases. For instance, an overrepresentation of Bacteroides species is associated with Type I diabetes mellitus (T1D) and various chronic gut disorders, including ulcerative colitis, inflammatory bowel disease, celiac disease, and colorectal cancer. Similarly, Naegleria fowleri, a free-living amoeba, causes …

Quantifying Temperature Effects On Developmental Rate And Plant Quality Of Compact Container-Grown Tomato (Solanum Lycopersicum), Morgan Humphrey

Horticulture Undergraduate Honors Theses

Mean daily temperature effects on plant development rates and quality were evaluated for compact container-grown tomato (Solanum lycopersicum). Compact tomato varieties ‘Siam’ and ‘Red Velvet’ were grown in greenhouses at 18 to 26 °C (Experiment 1) and 20 to 30 °C (Experiment 2) under supplemental high-pressure sodium lighting and 16-hour photoperiod. The number of days to first open flower, first ripe fruit, and from flower to ripe fruit were measured and development rates calculated by taking the reciprocal (e.g. 1/days). Temperature effects were predicted by fitting a linear (for first open flower) and a nonlinear exponential function (for …


The Living Library Of Dune, Josey W. Wilson May 2025

The Living Library Of Dune, Josey W. Wilson

Architecture Theses

This thesis investigates how language – as a natural, poetic force – can serve as a generative tool in architectural design. It argues that architecture must reclaim its mythopoetic roots, and that through the reintegration of narrative and literary language, built space can once again become a vessel for memory, cultural identity, and transformation.

As both a method and muse, Frank Herbert’s Dune becomes the central literary source for my resulting architectural design. This subjective translation takes form in The Living Library of Dune, a project located in Tacoma, Washington.

The final design of this thesis does not simply present …


Identification Of Mitochondrial Defects And Metabolic Consequences In Lynch Syndrome-Related Endometrial Cancer, Mikayla Bowen May 2025

Identification Of Mitochondrial Defects And Metabolic Consequences In Lynch Syndrome-Related Endometrial Cancer, Mikayla Bowen

Dissertations and Theses (Open Access)

Lynch syndrome (LS), defined by mutations in DNA mismatch repair genes including MSH2, carries a 60% lifetime risk of developing endometrial cancer (EC). Mismatch repair deficiency (MMRd) causes hypermutability, which is assumed to be the main driver of LS-related EC development. However, incomplete penetrance of EC development in women with LS suggests that other modulators are at play. The broad hypothesis of this dissertation is that MMRd causes consequences beyond hypermutability to impact LS-related EC development. Recent studies utilizing our lab’s Msh2-deficient mouse model for LS-EC revealed mitochondrial dysfunction in EC pathogenesis. This new insight led to the …

Development Of Lineal Energy Spectrum-Based Biological Effects Models For Protons, Joseph M. Decunha, Fada Guan, David Grosshans, Zhongxing Liao, Dragan Mirkovic, Oleg Vassiliev, Radhe Mohan

Dissertations and Theses (Open Access)

In this dissertation, methods are developed and described to allow for the rapid calculation of microdosimetric spectra (specifically, lineal energy) for protons. SuperTrack, a GPU-accelerated tool for calculation of microdosimetric spectra was developed and is capable of computing lineal energy spectra up to 5000x faster than using Geant4 directly. Proton lineal energy spectra generated by SuperTrack are indistinguishable from those generated by Geant4. With SuperTrack, large libraries of lineal energy spectra for monoenergetic protons spanning 0-300 MeV have been developed. The proton lineal energy spectra calculated by SuperTrack have been compared to experimental measurements made by a tissue equivalent proportional …

Risky Genes: The Impact Of Social Determinants Of Health On Dna Methylation In Indigenous Communities, Ella Martin May 2025

Risky Genes: The Impact Of Social Determinants Of Health On Dna Methylation In Indigenous Communities, Ella Martin

Celebrating Scholarship and Creativity Day (2018-)

Epigenetics is the study of molecular modifications to DNA structure that do not impact the sequence of the DNA itself. This biological study works to link health outcomes later in life with environmental interactions that affect our genetic predispositions. These complex factors can greatly impact longevity and quality of life. DNA methylation is one type of epigenetic mark that happens through natural biological processes. However, this marking has been shown to be detrimental to the process of aging and can be accelerated by harmful exposures such as stress, substance-use, or chemicals in the environment. Exposure to these compounds is exasperated …

Metabolic And Microbial Crossroads: Sodium-Glucose Cotransporter-2 Inhibitors And Urinary Tract Infections In (Asian) Diabetes Care, Rob E. Carpenter Apr 2025

Metabolic And Microbial Crossroads: Sodium-Glucose Cotransporter-2 Inhibitors And Urinary Tract Infections In (Asian) Diabetes Care, Rob E. Carpenter

Human Resource Development Faculty Publications and Presentations

The global rise of type 2 diabetes, particularly in Asian populations, has led to widespread adoption of sodium-glucose cotransporter-2 (SGLT2) inhibitors for glycemic control. While effective, these agents elevate the risk of urinary tract infections (UTIs) by inducing glycosuria, which creates a nutrient-rich environment that favors uropathogen growth. Asian individuals may be disproportionately vulnerable to SGLT2 inhibitor–associated UTIs due to a confluence of factors, including lower body mass index, increased visceral adiposity, congenital urinary tract anomalies, and genetic polymorphisms that impair uroepithelial integrity and immunity. This review integrates emerging evidence on the molecular, anatomical, and immunometabolic mechanisms that underlie infection …

Identification of isocitrate dehydrogenase (IDH) mutations has uncovered the crucial role of metabolism in gliomagenesis. Oncolytic herpes virus (oHSV) initiates direct tumor debulking by tumor lysis and activates anti-tumor immunity, however, little is known about the role of glioma metabolism in determining oHSV efficacy. Here we identify that oHSV rewires central carbon metabolism increasing glucose utilization towards oxidative phosphorylation and shuttling glutamine towards reductive carboxylation in IDH wildtype glioma. The switch in metabolism results in increased lipid synthesis and cellular ROS. PKC induces ACSL4 in oHSV treated cells leading to lipid peroxidation and ferroptosis. Ferroptosis is critical to launch an …

IntroductionHumans have used wood as a construction material throughout history. Currently, mass timber products, such as cross-laminated timber (CLT), are becoming more popular as a structural material, since they are renewable and have a lower carbon footprint than concrete or steel. Nonetheless, some building types, such as healthcare, veterinary, and food manufacturing, avoid using structural mass timber due to concerns about microbial growth in the event of wetting. One solution is to use protective coatings on mass timber products to increase moisture resistance, although the coatings themselves may generate concerns about volatile organic compound (VOC) emissions. Natural uncoated wood also …

Biochemical And Structural Insights Into The Yersinia Effector Yopm And Its Negative Regulation Of The Pyrin Inflammasome, Bethany Wairimu Mwaura Apr 2025

Biochemical And Structural Insights Into The Yersinia Effector Yopm And Its Negative Regulation Of The Pyrin Inflammasome, Bethany Wairimu Mwaura

Dartmouth College Ph.D Dissertations

Bacteria utilize sophisticated secretion systems to inject effectors into host cells in order to facilitate their survival and replication in the host. Some pathogenic species of Gram-negative bacteria use a conserved contact-dependent T3SS to inject a wide array of effectors. While the effectors diverge in their structures, functions and cell-localization, the T3SS is well conserved. Several effectors discussed in this thesis target key host inflammasome responses. The focus of this work is how the Yersinia effector YopM inhibits the pyrin inflammasome. During Yersinia infection, two effectors, YopE and YopT inadvertently activate the pyrin inflammasome while targeting RhoA to avoid phagocytosis. …

Deconstructing Ancient Allegories: Eleanor Antin’S 'Historical Takes' On Subverting Classical Motifs And Typologies, Lainey Tomasoski Apr 2025

Deconstructing Ancient Allegories: Eleanor Antin’S 'Historical Takes' On Subverting Classical Motifs And Typologies, Lainey Tomasoski

Undergraduate Theses in Art History

The New York-born artist Eleanor Antin erupted into the male-dominated American conceptual photography art scene in the 1960s and 70s with feminist works that reimagined the female body in terms of representation and history. In congruence with the feminist and civil rights movements, conceptual photography represented a shift in how art was utilized to criticize the social and political institutions in which it is rooted. Antin and other feminist artists engaging in conceptual photography and video played with the embodiment of characters, performance of the body, and an intrinsic “self-reflexivity” of subject, viewer, and artist. However, Antin pivoted her work …


Valuing Worker Authenticity, Dallan F. Flake Apr 2025

Valuing Worker Authenticity, Dallan F. Flake

William & Mary Law Review

Title VII of the Civil Rights Act of 1964 protects workers from discrimination because of their race, color, religion, sex, or national origin. Controversially, courts do not typically extend this protection to individual expression tied to a protected trait, such as a Black employee who wears their hair in dreadlocks or a Latino employee who speaks Spanish on the job. Judicial unwillingness to protect employee self-expression tied to a protected trait causes employees who identify with marginalized groups to suppress their identities to conform with mainstream culture—often at tremendous costs to themselves and the organizations they work for.

Nanosecond Pulsed Electric Field And Plasma Jets For Cancer Therapy, Edwin Ayobami Oshin Apr 2025

Nanosecond Pulsed Electric Field And Plasma Jets For Cancer Therapy, Edwin Ayobami Oshin

Biomedical Engineering Theses & Dissertations

Nanosecond pulsed electric field (nsPEF) employs nanosecond-duration, high voltage pulses to induce oxidative stress, leading to temporary or permanent damage to cells or tissue (also known as reversible and irreversible electroporation), and has been considered a promising approach for cancer therapy. In parallel to this, nanosecond pulsed atmospheric pressure plasma jets (ns-APPJs) have also shown to be effective in inactivating cancer cells or increasing sensitivity of cells to electric fields. ns-APPJs are known to generate reactive chemical agents, including reactive oxygen and nitrogen species (RONS) which induces oxidative stress resulting in cell proliferation, apoptosis, and necrosis. In this dissertation, a …

Structural Assembly Of The Pas Domain Drives The Catalytic Activation Of Metazoan Pask, Sajina Dhungel, Michael Xiao, Rajesh Rajaian Pushpabai, Chintan K. Kikani

Biology Faculty Publications

PAS domains are ubiquitous sensory modules that transduce environmental signals into cellular responses through tandem PAS folds and PAS-associated C-terminal (PAC) motifs. While this conserved architecture underpins their regulatory roles, here we uncover a structural divergence in the metazoan PAS domain-regulated kinase (PASK). By integrating evolutionary-scale domain mapping with deep learning-based structural models, we identified two PAS domains in PASK, namely PAS-B and PAS-C, in addition to the previously known PAS-A domain. Unlike canonical PAS domains, the PAS fold and PAC motif in the PAS-C domain are spatially segregated by an unstructured linker, yet a functional PAS module is assembled …
