Exploring Engineering Technology: A Multi-Year, Multidisciplinary Project-Based Engineering Technology Workshop, Benito Mendoza, Angran Xiao, Muhammad Ummy

Publications and Research

Many students enter engineering technology programs with a limited understanding of disciplinary differences, curricular expectations, and career pathways, contributing to early dissatisfaction and attrition. To address this challenge, we developed Exploring Engineering Technology, a multidisciplinary, project-based workshop that introduces students to Mechanical, Electrical, and Computer Engineering Technology through a shared robotic systems project. This paper presents a multi-year design-based educational research (DBER) study documenting the iterative refinement and sustained implementation of the workshop across three consecutive summers (2023–2025) at a large urban public college. Using a consistent post-workshop survey administered across cohorts and aggregate student progression indicators, we examine …

A Computational Micropatterning Approach To Study Caveolae And Protein Localization In Vascular Biology, Andrew B. Grespin

Electronic Theses and Dissertations

Caveolae are specialized, flask-shaped membrane invaginations highly expressed in endothelium and dysregulated in atherosclerosis. Caveolae play a central role in buffering membrane tension, yet the principles governing their spatial organization remain elusive. Thus, we sought to generate the most comprehensive and systematic analysis of blood vessel caveolar spatial organization. However, cell culturing, the backbone of human-focused biological research, does not standardly do well to model physiologically relevant cell behaviors such as migration or polarity-based tissue formation, particularly for punctate proteins and structures like caveolae. Micropatterns are cell-adhesive shapes that biophysically confine cell(s) to a user defined geometry which stereotype organelle …

Designing Equity With Ai: Scaffolding, Offloading, And Translation For Students With Learning And Attention Differences, Oksana Hagerty

Teaching & Learning with AI

This session positions AI tools as a mechanism for supporting students with learning and attention differences grounded in theories of distributed cognition. It distinguishes cognitive barriers arising from peripheral demands from those related to conceptual understanding and higher cognitive tasks. Drawing on scaffolding, cognitive offloading, and translation, the session argues for equity through intentional task design rather than individual exception. It concludes by examining the pedagogical trade-offs between AI-supported cognition and the pursuit of tool-independent mastery.

Phase-Resolved Measurement And Arbitrary Mode Conversion Of Structured Light, Somayeh Ghazanfarpour

Electronic Theses and Dissertations

This dissertation presents a single-shot phase and amplitude retrieval technique based on spatial light modulator (SLM)-based digital holography. The proposed method enables accurate reconstruction of complex optical fields from a single interferogram, reducing sensitivity to environmental fluctuations and improving experimental stability compared to conventional multi-shot approaches. In addition, a programmable arbitrary mode converter is developed using SLM-based wavefront shaping. By introducing controlled astigmatism and engineering the differential Gouy phase between orthogonal components, the system enables flexible transformation between structured light modes, including Hermite–Gaussian and Laguerre–Gaussian beams. Numerical results demonstrate reliable phase recovery and efficient mode conversion, validating the performance of …

Congestion Pricing: A Comprehensive Look At International Congestion Pricing Models And Applying Them To The United States, Ian Ertel

Electronic Theses and Dissertations

Urban traffic congestion imposes large costs through wasted time, excess fuel consumption, air pollution, and lost productivity. Although congestion pricing has been recognized as the economically efficient remedy since Pigou and Vickrey, implementation has been rare. This thesis examines the conditions under which congestion pricing succeeds by analyzing three pioneering cases: London, Singapore, and New York City. Across all three, charges reduced traffic volumes and improved speeds within the priced zones. Benefits extended beyond cordon boundaries, with measurable improvements on untolled suburban roads. The distributional effects depended on how revenues were recycled rather than on the charge itself. Political viability, …

Induction Programming For Novice Special Education Directors: The Significance Of Informal Supports In The Absence Of Formal Structures, Julie E. Rottier-Lukens

Electronic Theses and Dissertations

The role and responsibilities of a special education director are unique and highly complex when compared to other district-level leadership roles. Since the Individuals with Disabilities Education Act (IDEA) passed in 1975, states gradually increased requirements for certification of these administrative roles, more clearly defining the criteria and standards to incorporate within preparation programs. Despite improvements in preparation programs for special education directors, there continues to be variation in preparation and certification requirements across states and persistent challenges with shortages of special education directors. After completing a preparation program, what support exists for novice special education directors to help them …

Interactive Social Game Design For Sustainability Learning, Kayla Mattson, Kayla Huffman, Megha Thottam, Shreeya Koritala

Computer Science and Engineering Senior Theses

Our Roots is a community-centered, web-based social game designed to improve sustainability education by turning everyday environmental actions into shared, visible progress. While many existing tools provide information about sustainability, they often focus on individual tracking and short-term motivation, which can lead to disengagement over time. This project addresses that gap by reframing sustainability as a social practice: users log real-world sustainable behaviors, earn points, and see those actions represented as growth in both personal and community digital gardens. By combining friendly competition, peer visibility, and collective outcomes, the platform encourages users to view sustainability not as an isolated task, …

Avoiding Libel (And Possible Defamation Consequences) In The Age Of Ai Detection: Lesson From Journalism For Higher Education, Thomas A. Pear

Teaching & Learning with AI

This presentation argues that educators should not rely solely on AI‑detection tools when accusing students of AI‑assisted plagiarism. Instead, it proposes using detector scores only as “pedagogic probable cause,” a term developed by the author that signals when a submission warrants closer review, not a basis for disciplinary action. The presentation opens by outlining the limitations of current AI detectors, including high false‑positive rates and documented bias against non‑native English writers.

The presentation then reframes the issue through two complementary lenses: investigative journalism and defamation law. Drawing on the Woodward‑and‑Bernstein “two‑source rule,” it contends that a single detector score …

Data Governance Maturity, Ai Integration, And Equity In Colorado K-12 Public Schools, John R. Curtin

Electronic Theses and Dissertations

Colorado's 179 K-12 public school districts operate as autonomous governance units, each responsible for securing and managing student data assets that span health, financial, residential, and academic records. The accelerating integration of artificial intelligence (AI) and machine learning (ML) tools into administrative workflows, productivity software, and instructional platforms has fundamentally altered the risk landscape for student data, yet governance frameworks at the state, district, and school levels have not kept pace. This dissertation investigates whether Colorado's decentralized educational governance structure is institutionally capable of producing equitable, secure, and sustainable data governance outcomes in the AI era.

Design Principle For Staple-Mediated Stabilization Of Peptides And Proteins, Samantha C. Hatfield

Theses and Dissertations

Macrocyclization, or stapling, has emerged as a powerful strategy to enhance the stability and function of peptides and proteins by constraining their conformational ensembles. Stapling can improve thermodynamic stability, increase resistance to proteolytic degradation, and enhance biomolecular recognition, making it particularly valuable for the development of peptide-based therapeutics. Despite these advantages, staple design remains largely empirical, relying on iterative screening of linker chemistries, lengths, and attachment sites. This trial-and-error approach limits scalability and hinders the rational design of stabilized peptide systems. In this work, we address this challenge by integrating large-scale experimental datasets with molecular dynamic simulations to develop predictive …

Improving Cluster Expansion Efficiency And Generalizability, Samuel D. Bills

Undergraduate Honors Theses

The cluster expansion (CE) method is a powerful framework for modeling alloy systems by linking atomic configurations to thermophysical properties. However, constructing accurate and robust CE models requires careful selection of both training structures and cluster bases. In this work, we investigate how structure enumeration and cluster selection strategies influence CE performance in binary face-centered cubic alloys using a Julia-based implementation. Model performance is evaluated using empirical risk and the generalized aliasing decomposition (GAD), which provides insight into the relationship between model complexity and generalization error. We find that physically motivated selection strategies that prioritize small clusters consistently outperform approaches …

Electrically Operated Throttle For Niu Supermileage Ice, Ashley Wubben, Natey Ericson, Adrianne Dela Rosa

Exceptional Scholarship & Artistry

This report presents the design, prototyping, and evaluation of an electronically operated throttle system for the NIU Supermileage internal combustion engine (ICE). The original mechanically actuated throttle experienced sticking, slippage, and inconsistent response, which reduced repeatability and driver confidence. To address these issues, the team developed a compact electronic throttle system using an Arduino nano, a linear potentiometer for driver input, and a servo motor to actuate the throttle valve. The system was integrated with custom mounting and a circuit system that enabled throttle response. Engineering analysis was used to estimate the torque required to actuate the throttle, with attention …

Evaluation And Distillation Of Source Code Generation Tasks By Large Language Models, Danny Brahman

Electronic Theses and Dissertations

Large Language Models (LLMs) are predominantly assessed based on their common sense reasoning, language comprehension, and logical reasoning abilities. While models trained in specialized domains like mathematics or coding have demonstrated remarkable advancements in logical reasoning, there remains a significant gap in evaluating their code generation capabilities. Existing benchmark datasets fall short in pinpointing specific strengths and weaknesses, impeding targeted enhancements in models’ reasoning abilities to synthesize code.

To bridge this gap, this thesis introduces two novel contributions: CodeEval and CodeQual. CodeEval is an innovative, pedagogical benchmarking method that mirrors the evaluation processes encountered in academic programming courses. It comprises …

The Organizational Experience Of Next Gen Learning Through Portrait Of A Graduate, Kathleen J. Campbell

This qualitative single-case study investigates the organizational journey of navigating the complexities of systemic transformation. In 2021, Silver Peak School District (SPSD; a pseudonym), a rural educational organization in the western United States, implemented a graduate competency framework known as Portrait of a Graduate. This study analyzed the experiences of teachers, instructional coaches, and principals with the explicit Portrait policies, practices, and resource flows of five learning structures—graduate competencies (in SPSD, this is analogous to Portrait), deeper learning, agency, performance assessment, and teaching culture—in a district in the messy middle of Portrait adoption. By focusing on a district situated in …

She Believed She Could, So She Did: A Lifecycle Approach To Understanding Leadership And Self-Efficacy Development In Women Astronauts, Savanah Faith Sellars Bray

Electronic Theses and Dissertations

This dissertation examines how women leaders develop and sustain self-efficacy, and develop as leaders, throughout their lives. Although decades of research document the barriers women face navigating leadership journeys, including the challenges described in the Women’s Leadership Labyrinth of prejudice, discrimination, and childcare issues, existing literature offers limited insight into how women actively build belief in their capacity to lead and accomplish their goals. Further, research consistently shows that women report lower leadership self-efficacy than men, even with comparable experience, yet the developmental processes that shape this gap, beginning in childhood, remain underexplored. Guided by self-efficacy research and its four …

Projected Climate Change Impacts On Soil Greenhouse Gas Emissions From A Restored Freshwater Marsh, Annika Hendrickson

University Honors Theses

Wetlands provide valuable ecosystem services, one of which is a wetlands ability to sequester carbon. Climate change and human land use threaten a wetlands ability to do so. Globally, 21% of wetlands have been lost since the 1700s. As a result, restoration of wetlands has been increasing. However, wetlands in the process of restoration emit more methane than degraded ones, and as the climate continues to change, these fluxes could respond. Projected sea level rise is expected to cause salt water to infiltrate coastal freshwater systems, increasing the salinity. Past research has found that increased salinity has led to suppressed …

Defying Impossibility: Critical Qualitative Reorientations To Black Lgbtqia+ Sense Of Belonging, Olivia H. Hunte

Electronic Theses and Dissertations

Belonging is a human need central to survival and can be cultivated within all spheres of life. Social environments are vital for experiencing a sense of belonging. In some social environments, Black LGBTQIA+ people encounter greater impediments to their daily lives with consequences for survival, including threatening their belonging needs. Within the United States, systems of oppression create and inform conditions within social environments that can potentially thwart pathways to belonging for Black LGBTQIA+ people. Thus, fulfillment of belonging needs for Black LGBTQIA+ people is one of nuance, pain, resilience, hope, harm, trauma, resistance, and healing; scant research is available …

Melomove: Self Paced, Movement-Music Tangible Interaction For Older Adults In Public Outdoor Space, Fatima Badmos, Emma Murphy, Peterson Jean, Paula Kelly, Damon Berry

Research Outputs: 2025-Present

Designing interactive outdoor technologies for older adults often emphasises tracking and exercise, which can conflict with enjoyment, autonomy, and the realities of public space. Previous work on tangible systems for older adults have largely focused on indoor, supervised, or therapeutic contexts, leaving limited guidance for outdoor community settings. We present Melomove, a 3D printed handheld dumbbell shaped device that maps movement to real-Time musical feedback for self-paced exploration. We report an exploratory outdoor workshop with 16 older adults (63-93) in a campus bandstand, using structured observations and interviews to examine how a tangible movement music interface can scaffold agency, affective …

Higher Education Institutions In U.S. Blockchain Innovation Governance Documents, Clarissa Terracciano

Electronic Theses and Dissertations

Blockchain technologies have attracted growing attention as an evolution of digital recordkeeping, prompting interest in higher education governance, credentialing, and data management. Yet, no systematic analysis exists on how U.S. government blockchain documents define institutional roles and governance authority within higher education institutions. As the national blockchain innovation system expands through governance infrastructure, the inclusion of higher education institutions as governing actors is imperative for coherent and equitable deployment. This qualitative study examines what roles the U.S. government blockchain documents assign to higher education institutions within the national blockchain innovation system.

Using innovation systems theory, particularly the triple-helix model of …

Explainable Multi-Agent Llm Framework For Phishing Email Detection Via Role-Specialized Evidence Decomposition, Tanya Yadav, Mohammad Masum

Faculty Research, Scholarly, and Creative Activity

Phishing email remains a persistent and operationally critical cybersecurity threat, yet existing detection approaches, including traditional machine learning and single-pass large language model systems, either lack native interpretability or provide explanations that are difficult to standardize and audit. This paper introduces an explainable multi-agent LLM framework that decomposes phishing evidence across three role-specialized agents focused on linguistic patterns, psychological manipulation, and sender identity consistency. The framework then aggregates specialist outputs through schema-governed synthesis, enabling each intermediate and final decision to be structured, comparable, and auditable. The central contribution is the treatment of role-specialized evidence decomposition and explanation structure as first-class …

Using Ai To Add Tables Of Contents To Cataloging Records, Marissa Bischoff, Lance Hansen

Faculty Publications

A table of contents and summary are important metadata that improve the discoverability and description of our materials. They are optionally included in catalog records, though, because transcribing these by hand is time intensive.

We sought the most efficient way to scan and AI format the table of contents pages for inclusion in the 505 field of catalog records.  We explored different AI software, iterative prompting and the time-effectiveness of the process, in comparison to hand-typed metadata fields.
