Description
#VanLife is a long-time, up and coming lifestyle movement on social media centered around the process of leaving the traditional nine-to-five work week for a life on the road in a camper van. While the ‘hippie-esque’ vagabond lifestyle has its humble roots long before the turn of the century, the inception of social media platforms such as Instagram and Pinterest have fueled the more recent popularization of a full-time life on the road. #VanLifers often freelance on the road, work part time jobs, or gain sponsorships to help fund their traveling and humble lifestyle.
As the #VanLife craze continues to grow, new businesses are finding ways to meet the demand in the market. For #Vanlifers who own and operate their own camper vans, specialized companies like GoWesty, Vanagain, and Boxeer offer a full range of parts, upgrades, and custom mechanical and systems conversion kits to keep these vans on the road as OE manufacturers discontinue production on these parts. For those who have an itch to try out the #VanLife for a shorter period and without the financial commitment, companies like Roamerica, TontoTrails, and adventureRIGS offer nightly and weekly rental opportunities on fully-outfitted campervans ready to hit the road.
For my Honors Project I wrote a complete analysis on the history, development, and modernization of the #VanLife movement. With plans to take to the road for an extended period of time after graduation, I also developed a complete financial plan for a one-year #VanLife experience. The financial plan includes a comprehensive set of budgets that scrutinize the start-up an operational costs of the #VanLife and associated travel.

Description
Alzheimer’s Disease (AD) affects over 5 million individuals in the U.S. and has a direct cost estimated in excess of $200 billion per year. Broadly speaking, there are two forms of AD—early-onset, familial AD (FAD) and late-onset-sporadic AD (SAD). Animal models of AD, which rely on the overexpression of FAD-related mutations, have provided important insights into the disease. However, these models do not display important disease-related pathologies and have been limited in their ability to model the complex genetics associated with SAD.
Advances in cellular reprogramming, have enabled the generation of in vitro disease models that can be used to dissect disease mechanisms and evaluate potential therapeutics. To that end, efforts by many groups, including the Brafman laboratory, to generated patient-specific hiPSCs have demonstrated the promise of studying AD in a simplified and accessible system. However, neurons generated from these hiPSCs have shown some, but not all, of the early molecular and cellular hallmarks associated with the disease. Additionally, phenotypes and pathological hallmarks associated with later stages of the human disease have not been observed with current hiPSC-based systems. Further, disease relevant phenotypes in neurons generated from SAD hiPSCs have been highly variable or largely absent. Finally, the reprogramming process erases phenotypes associated with cellular aging and, as a result, iPSC-derived neurons more closely resemble fetal brain rather than adult brain.
It is well-established that in vivo cells reside within a complex 3-D microenvironment that plays a significant role in regulating cell behavior. Signaling and other cellular functions, such as gene expression and differentiation potential, differ in 3-D cultures compared with 2-D substrates. Nonetheless, previous studies using AD hiPSCs have relied on 2-D neuronal culture models that do not reflect the 3-D complexity of native brain tissue, and therefore, are unable to replicate all aspects of AD pathogenesis. Further, the reprogramming process erases cellular aging phenotypes. To address these limitations, this project aimed to develop bioengineering methods for the generation of 3-D organoid-based cultures that mimic in vivo cortical tissue, and to generate an inducible gene repression system to recapitulate cellular aging hallmarks.

In Spring 2015, I decided to study abroad in Granada, Spain. After scouring the Internet, I realized there was a lack of resources and information for study abroad students coming to the city. I decided to use my thesis project as an opportunity to create a multimedia, interactive e-book to help prospective study abroad students. This book walks them through what steps they need to take to prepare themselves and functions as a guide for when they arrive. It is a culmination of my own research, interviews with locals and surveys amongst other study abroad students.

Description
Background: Noninvasive MRI methods that can accurately detect subtle brain changes are highly desirable when studying disease-modifying interventions. Texture analysis is a novel imaging technique which utilizes the extraction of a large number of image features with high specificity and predictive power. In this investigation, we use texture analysis to assess and classify age-related changes in the right and left hippocampal regions, the areas known to show some of the earliest change in Alzheimer's disease (AD). Apolipoprotein E (APOE)'s e4 allele confers an increased risk for AD, so studying differences in APOE e4 carriers may help to ascertain subtle brain changes before there has been an obvious change in behavior. We examined texture analysis measures that predict age-related changes, which reflect atrophy in a group of cognitively normal individuals. We hypothesized that the APOE e4 carriers would exhibit significant age-related differences in texture features compared to non-carriers, so that the predictive texture features hold promise for early assessment of AD. Methods: 120 normal adults between the ages of 32 and 90 were recruited for this neuroimaging study from a larger parent study at Mayo Clinic Arizona studying longitudinal cognitive functioning (Caselli et al., 2009). As part of the parent study, the participants were genotyped for APOE genetic polymorphisms and received comprehensive cognitive testing every two years, on average. Neuroimaging was done at Barrow Neurological Institute and a 3D T1-weighted magnetic resonance image was obtained during scanning that allowed for subsequent texture analysis processing. Voxel-based features of the appearance, structure, and arrangement of these regions of interest were extracted utilizing the Mayo Clinic Python Texture Analysis Pipeline (pyTAP). Algorithms applied in feature extraction included Grey-Level Co-Occurrence Matrix (GLCM), Gabor Filter Banks (GFB), Local Binary Patterns (LBP), Discrete Orthogonal Stockwell Transform (DOST), and Laplacian-of-Gaussian Histograms (LoGH). Principal component (PC) analysis was used to reduce the dimensionality of the algorithmically selected features to 13 PCs. A stepwise forward regression model was used to determine the effect of APOE status (APOE e4 carriers vs. noncarriers), and the texture feature principal components on age (as a continuous variable). After identification of 5 significant predictors of age in the model, the individual feature coefficients of those principal components were examined to determine which features contributed most significantly to the prediction of an aging brain. Results: 70 texture features were extracted for the two regions of interest in each participant's scan. The texture features were coded as 70 initial components andwere rotated to generate 13 principal components (PC) that contributed 75% of the variance in the dataset by scree plot analysis. The forward stepwise regression model used in this exploratory study significantly predicted age, accounting for approximately 40% of the variance in the data. The regression model revealed 5 significant regressors (2 right PC's, APOE status, and 2 left PC by APOE interactions). Finally, the specific texture features that contributed to each significant PCs were identified. Conclusion: Analysis of image texture features resulted in a statistical model that was able to detect subtle changes in brain integrity associated with age in a group of participants who are cognitively normal, but have an increased risk of developing AD based on the presence of the APOE e4 phenotype. This is an important finding, given that detecting subtle changes in regions vulnerable to the effects of AD in patients could allow certain texture features to serve as noninvasive, sensitive biomarkers predictive of AD. Even with only a small number of patients, the ability for us to determine sensitive imaging biomarkers could facilitate great improvement in speed of detection and effectiveness of AD interventions..

Woman with Wanderlust is a travel blog made to break down the stereotypes of female travelers as they are portrayed in mass media. The idea came to me when I was preparing to study abroad in Morocco and every person I talked to felt the need to remind me how dangerous the world was for a woman on her own. There were many references to the popular movie ‘Taken’ starring Liam Neeson. When I decided I wanted to continue the blog on my backpacking trip through Europe, once again ‘Taken’ was referenced but people also insisted I was going to fall in love with an Italian man and never come home. It felt, to me, that the world saw the female traveler as naive and weak or in need of a man in her life. In contrast men are often encouraged to take years off to travel, to seek adventure or find themselves.
I decided I could use my education from the Cronkite School in writing, photography and social media to produce a resource for women looking to travel abroad. I could tell stories of my personal experiences that could both inspire and prove that a solo trip can be done. I also wanted to touch on topics that are not generally covered by popular travel blogs since they are specific to women. Topics like how to dress, making sure you travel during the day if you’re traveling alone and finding birth control or feminine hygiene products when you are traveling.
I funded the trip myself and currently the blog is designed, written and photographed entirely by me. Moving forward I would like to feature other women on my blog, especially those who have made travel a priority or a career. I plan on continuing to build the blog, hopefully gaining sponsors and becoming a more well known resources, and helping change the landscape of travel and travel blogging to become more female friendly.

The research objective is to maintain the A4 nanobody stability during dialysis. Various dialysis buffers were tested and compared, including PBS with varying amounts of the detergent, Tween: low, high, none. Furthermore, PBS, Tris, and HEPES, were tested and compared. PBS without Tween was the worst for preserving A4 stability. PBS was determined to be a better dialysis buffer than Tris or HEPES. To find the optimum buffer, other buffers will be tested and compared with PBS; methods such as gravity filtration and lyophilization will be considered as alternatives to dialysis.

Does assisted cycle therapy influence activities of daily living in older adults with Down syndrome?
Description
The aim of this study is to examine the relationship between Assisted Cycle Therapy, leisure time activity levels, fine motor control, and grip force in older adults with Down syndrome (DS), all of which affect activities of daily living (ADL) and therefore quality of life. This is relevant because this particular group is at risk for developing early onset Alzheimer's disease (AD), which presents itself uniquely in this population. The parent or guardian of six participants with DS completed Godin's Leisure Time Exercise Questionnaire and the participants themselves completed Purdue Pegboard and grip force assessments before and after an 8-week exercise intervention. The results were inconsistent with past research, with no change being seen in fine motor control or grip force and a decrease being seen in leisure activity. These findings are indicative of the importance of the effect of fatigue on leisure activity as well as maintaining elevated heart rate throughout exercise interventions.

Inspired by my own experiences, I began this study to examine students' cultural engagement while studying abroad. Students' motivations to study abroad vastly vary and no two experiences are the same, due to the multitude of factors involved. Study abroad program providers and organizations frequently cite intercultural competence as a vital skill in the 21st century for all young professionals to build, and is often a goal of students to develop through their study abroad experiences. Before departure, some students may have a romanticized, grand vision of integrating themselves in a foreign culture and learning the language. Upon arrival, reality may prove to be quite different and students can get swept up in the novelty of living in a new environment and traveling with their new American friends from the same program. The vision of intercultural competence and foreign language acquisition gradually fades when realizing just how difficult they both are to achieve, especially in such a short time period. My hope is that this study can highlight issues that returned students of study abroad programs faced while abroad and can provide valuable insight for future study abroad participants into how to become more immersed in their host culture. By creating awareness of the merits of intercultural competence and the methods to develop it through study abroad, future students can become better equipped to have a more enriching experience. https://cultureasustudyabroad.wordpress.com/
