A Double-Edged Sword? Liana Wood Decomposes Faster Than Tree Wood, Denis Mburu Njoroge, Aphrodis Munyaneza, Juan Zuo, Gbadamassi G. O. Dossa, Douglas Schaefer, Rhett D. Harrison, Stefan A. Schnitzer, J. Hans C. Cornelissen

Biological Sciences Faculty Research and Publications

Lianas are increasing in many forests and show higher stem turnover rates and different chemical profiles compared with trees. However, liana deadwood decomposition dynamics have been overlooked. We redress this omission and hypothesize that liana wood decomposes faster than tree wood due to its larger vessels and higher nutrient content than trees, resulting in greater activity of both microbial and invertebrate decomposers. We tested this hypothesis in a common-garden decomposition experiment with deadwood of two size classes (2.5 and 4 cm diameter) belonging to 12 liana and 12 tree species in tropical China. Liana wood decomposed 28.6% faster than tree …

Democratic Abundance: An Abundance That Works For Workers, Kate Andrias, Alexander Hertel-Fernandez

Faculty Scholarship

The “abundance agenda” identifies a worthy goal: to ask what people really need and to organize government to make sure there is enough of it, including by eliminating unnecessary delays and veto points. However, abundance’s theory of why government fails to provide the goods people need and how to change that reality falls short. As critics have argued, abundance is insufficiently attentive to questions of political power and distribution, undervalues democratic participation, and sidelines discussions about trade-offs, including around the importance of protecting labor standards and the environment. Centering the role of workers and organized labor helps respond to all …

From Prediction To Prevention: How The Va Uses Analytics To Reduce Chronic Disease And Mental Health Risk, Leelakrishna Angadala

Undergraduate Student Symposium

Predictive analytics has become an essential component of preventive care strategies within the Veterans Health Administration (VHA), which serves a medically and psychosocially complex population at elevated risk for chronic disease and mental health conditions. This research examines how the VHA has leveraged predictive analytics to improve early identification, prevention, and targeted intervention for chronic illnesses and mental health disorders. Specifically, it explores established initiatives such as the Care Assessment Needs (CAN) score for identifying veterans at high risk of hospitalization or mortality, the Reach Out, Stay Strong, Essentials for Veterans (REACH VET) program for suicide risk prediction and prevention, …

Targeting The Metabolic-Neurodegenerative Axis: In Silico Repurposing Of Fda-Approved Pleiotropic Metabolic Modulators For Alzheimer's Tau Protein, Maanya Chitrapu, Juhi Vora

Undergraduate Student Symposium

Extensive research has established a link between insulin deficiency and insulin resistance and Alzheimer's Disease (AD) type-neurodegeneration, coining it "Type 3 Diabetes". While research typically focuses on glucose regulation, the comparative structural efficacy of broader metabolic agents against neuropathology remains distinctively underexplored. This study addresses this gap by performing a novel in silico comparison of three drug classes (Glucose, Lipid, and Cardio-Metabolic regulators) to identify superior scaffolds for obstructing the pathological Tau protein, which plays a major role in causing AD through its hyperphosphorylation. The Tau paired helical filament (PDB ID: 5O3L) was retrieved from the RCSB Protein Data Bank. …

What Genograms Can Tell Us About Family Dynamics That Quantitative Data Cannot, Connor Mccarville, Jessica Frye, Maegan Mcdonough

Undergraduate Student Symposium

Genograms are an important clinical tool that is used to visually represent family relationships and their dynamics, but their effectiveness in empirical research remains limited. This mix-methods study examined the alignment between qualitative genogram visualizations and quantitative assessments of family dysfunctionality among individuals who exhibited high levels of risky sexual behavior. Based on preliminary data, currently with seven individuals with a high level of risky sexual behavior, we created genograms through interviews with young adult participants who described the emotional quality of each family relationship. Quantitative data on risky sexual behavior and whole family functioning were collected using the Family …

Tissue-Specific Stable Isotope Fractionation In Subarctic Pinniped Species, Morgan Michalek

Undergraduate Student Symposium

Stable carbon (δ¹³C) and nitrogen (δ¹⁵N) isotope ratios are widely used to evaluate marine mammal diet, trophic position, and nutrient assimilation. However, interpretation is often confounded by tissue-specific isotopic discrimination, which alters isotope ratios during nutrient assimilation and tissue synthesis. Quantifying these offsets is essential for ensuring accurate trophic reconstructions across multiple tissues with different biochemical compositions. This study measured δ¹³ and δ¹⁵N values in muscle, blood, blubber, brain, collagen, kidney, liver, skin, fur, and vibrissae of Steller sea lions (Eumentopias jubatus), harbor seals (Phoca vitulina), and northern fur …

Overcoming Gbm Stem Cell Resistance With Resveratrol Analog E03, Alma Partenza, Vansh Linga, Maanas Mallela

Undergraduate Student Symposium

Glioblastoma (GBM) is a highly aggressive brain tumor with poor prognosis, driven by GBM stem cells (GSCs) that promote growth, recurrence, and treatment resistance. The PI3K/AKT signaling pathway is frequently hyperactivated in GBM, contributing to cell survival and proliferation, making it a key therapeutic target. Resveratrol (RSV), a natural anticancer polyphenol downregulates AKT signaling but is limited by poor bioavailability and potency. We developed diaryl acrylonitrile analogs of RSV to improve potency, stability, and drug-like properties for targeting GSCs. This study aimed to synthesize, evaluate the anticancer activity of these analogs against GSCs, and elucidate their mechanism of action to …

Gene Loss And Ecological Adaptation In Honeybee Venom: Exploring The Absence Of Melittin In Apis Andreniformis, Diya Patel, Grace Wong, Rishubh Madaboosil, Kaylee Reyes Lazo, Jovonne Grant, Isabella Garcia

Undergraduate Student Symposium

Genetic divergence within the Apis honeybee genus is shaped by geography, climate, and ecological specialization, leading to variations in morphology, behavior, and venom composition. Comparative genomic analyses have revealed both gene loss and lineage-specific adaptations that contribute to these traits. In this study, we investigate the evolutionary, molecular, and biochemical factors influencing venom production across honeybee species, with a focus on the unexpected absence of a detectable melittin gene in Apis andreniformis (Black Dwarf Honeybee). While melittin constitutes 40-60% of the venom in Apis mellifera, BLAST searches failed to identify a homolog in A. andreniformis, despite its venom …

Is Left Ventricular Dysfunction Associated With Increased Risk Of Alzheimer's Disease Independent Of Classical Vascular Dementia Pathways?, Priyanshi Patel

Undergraduate Student Symposium

This poster examines the potential connection between left ventricular dysfunction and the risk of Alzheimer's disease in older adults. Studies suggest that reduced heart function may affect brain health by limiting blood flow to the brain, increasing inflammation, and interfering with the brain's ability to clear harmful proteins such as amyloid-β and tau. These processes resemble changes commonly seen in Alzheimer's disease. In population-based studies, individuals with heart failure or structural abnormalities of the left ventricle appear to have a higher risk of developing dementia, including Alzheimer's disease, even after accounting for major risk factors such as hypertension and clinical …

Pattern Formation In A Β-Amyloid Plaque Model For Alzheimer's Disease , Hannah Prudhomme

Undergraduate Student Symposium

Alzheimer's disease is a neurodegenerative disorder with complex physiological mechanism that are not fully understood. Over 7 million Americans are known to be living with the disease, and an Alzheimer's diagnosis accounts for 60-70% of dementia cases. Current hypotheses attribute the cause to an interplay between β-Amyloid plaques and neurofibrillary tangles, resulting in central nervous system disruption and decline in cognitive functioning. In this project, we study a spatial dynamical system model that incorporates the interaction between β-Amyloid monomers, oligomers, microglia, and interleukins in the context of plaque aggregation. We establish conditions for the existence and stability of a spatially …

Repetitive Mild Traumatic Brain Injury Exacerbates Cognitive Deficits In A Mouse Model Of Cerebral Amyloid Angiopathy, Lauren Rosenberg, Victoria Pullido-Correa, Ariana Hernandez, Chana Vogel, Bianca Echeverria, Iliana Uribe

Undergraduate Student Symposium

Traumatic brain injury (TBI) affects around 69 million people each year, with mild TBIs (mTBIs) making up the majority of cases. These injuries, often sustained during contact sports, military service, or incidents of domestic violence, typically involve brief or no loss of consciousness and few immediate symptoms. However, repeated occurrences significantly elevate the risk for long-term complications, including dementia. While repetitive in mTBI is strongly linked to chronic traumatic encephalopathy (CTE) and Alzheimer's disease (AD), the relationship with cerebral amyloid angiopathy (CAA), characterized by the accumulation of amyloid peptides in the cerebral vasculature, remains understudied. Given that CAA significantly contributes …

Virtual Reefscapes: Modeling Fish Abundance On Artificial And Natural Reefs In Broward County, Jesse Caruana Snachkus

Undergraduate Student Symposium

This project involved constructing a VR simulation of fish abundance on artificial and natural reefs in Broward County. Two environments, SS Tracey, and a section of the Florida Reef Tract, were created to highlight ecological differences between artificial and natural reef habitats. All environments and species models were designed in Blender, a 3D modeling software, and each fish species was animated to showcase naturalistic behavior. The completed assets were then assembled in VR using the Open Brush application. This project integrates art, technology, and ecology to make marine environments more accessible and engaging for a wide audience. A combination of …

Race-Based Violence Against Educators And School Personnel: The Roles Of Race And Harm, Jared Hunt

Theses and Dissertations from DePaul University

Educator-directed violence is a serious problem that has adverse effects on the careers and lives of those victimized. Educators and school personnel in the United States experience this violence within institutions that are shaped by long-checkered histories of racism and racial discrimination (Bickford and Clabough, 2021) that continue today (Carver-Thomas, 2018). Thus, there is a need to consider the roles of race and racism in the violence educators and school personnel experience. This study investigated educators’ and other school personnel’s experiences of physical and verbal/threatening violence, harm, and psychological distress. Through a racial stress and trauma framework, this study also …

Colonial Ambivalence And The Self: The Psychological Legacy Of Colonization, Nazia Khan

Theses and Dissertations from DePaul University

Colonization may disrupt a person’s sense of self by introducing conflicting identities, where one part of identity is tied to colonization while the other attempts to decolonize (David & Okazaki, 2006). This identity conflict may lead to psychological distress because these identities are often in opposition to one another. Although colonized individuals may have been forced to adopt the colonizer’s social norms, people may also incorporate colonization-influenced practices into their self and cultural identity with and without recognizing their colonial roots. Colonial ambivalence is introduced as the simultaneous holding of positive and negative feelings regarding one’s colonized background. Individuals from …

Automation Of Discovery And Classification Of Compact X-Ray Binaries In Globular Clusters, Justin Brooks

Theses and Dissertations from DePaul University

The discovery and classification of Compact X-ray Binaries (CXRBs) within globular clusters improves our understanding of stellar encounters, the evolution of globular clusters, accretion physics, and the high-energy physics of the compact objects involved in these systems. For this reason, scientists compare X-ray observations from the Chandra X-ray Observa?tory with visible and UV observations from the Hubble Space Telescope to find objects of unusual colors and magnitudes which might be CXRBs. However, this process is time-consuming and requires significant amounts of data and expertise to achieve reliable classifications. This paper de?scribes this process, as well as a proposed automated process …

Protective Row Covers For Management Of Flea Beetles In Organic Eggplant Production In The Southeastern Us, Elaine Losekamp, Robert Brockman, Viktor Halmos, Kathleen Fiske Pulliam, Ryan Kuesel, Ric Bessin, Delia Scott, Mark Williams, David Gonthier

Entomology Faculty Publications

Organic eggplant production in the United States is challenged by flea beetles, which stunt eggplant growth and reduce yield. Across four experiments between 2019 and 2024, we compared the effects of various pest management strategies on flea beetle abundance, damage, and marketable yield in eggplant production, focusing on row covers and organic insecticides in later years of the study. Treatments included fine-mesh row covers, organic insecticides, and untreated controls (all years); reflective plastic mulch (2019); various essential oils (2019–2020); conventional insecticide control (2019–2020); and spunbonded row covers (2019–2021). Low flea beetle pressure was observed in 2019 and 2020; consequently, experiments …

Raptor Abundance And Occupancy In Urban Parks Within Metropolitan Landscapes, Mary- Esther Leblanc

Posters - 2026

Rapid urbanization is one of the most significant and accelerating drivers of global biodiversity change, reshaping wildlife communities by fragmenting habitat, altering prey availability, and introducing human disturbances. Despite these pressures, some wildlife species are attracted to and may even flourish in urban settings, primarily because urbanization creates an altered landscape that often unintentionally provides resources functioning as components of habitat. (Chiron et al., 2024) Raptors, as apex predators within avian food webs, offer a valuable lens through which to examine these dynamics. While raptor communities are broadly negatively impacted by urbanization, some species can thrive in urban areas. (Leveau …
