OU Major: Computer ScienceResearch Mentor: Dr. Amy McGovernDescribe your undergraduate research or creative project:

Artificial neural networks (ANNs) are an effective tool for automatically locating bird roosts using radar. NEXt generation weather RADars (NEXRAD) are designed to collect data on weather, but they also pick up information on moving, airborne objects, including birds. NEXRAD helps ecologists to detect bird roost location, but this data is tedious to process manually. Therefore, ANNs detected the roosts automatically from a NEXRAD image dataset of purple martin and tree swallow roosts in the eastern U.S. Four types of radar field images, including reflectivity, velocity, Rho HV, and Zdr, were useful for finding roosts. The ANN achieved an accuracy, true positive rate, and true negative rate of around 80 percent each, showing that this method has potential as a tool for roost detection. Convolutional neural networks (CNNs), a type of ANN, were found to perform better than the traditional ANNs, achieving an accuracy, true positive rate, and true negative rate of over 90 percent each.

Even if you’re intimidated by reaching out to people, do it anyway because they often surprise you. I sent Dr. McGovern a cold email during first semester of my freshman year and asked if I could join her lab. I hadn’t met her before, but I saw her on the computer science faculty page, and I thought that her work looked interesting. Unexpectedly, she said yes, and I started doing research with her right away.

McMansions are the embodiment of capitalism's limitless consumption. These, in a maze of suburban streets, came to represent the "American Dream." This ideal has serious implications in US societies, on environments, and on individual health. Social and economic divides were established or reinforced by suburbanization. This lack of diversity has led to unfair stigmas applied to groups of people which has increased racism and xenophobia. With no regulations at the start of suburbanization and not enough in place now, homes are built using chemicals and compounds which poison the occupants. While lead and asbestos are now banned, many chemicals are still in use which are proven to or show a strong correlation to the degradation of human health. This is not to mention the sourcing of these materials and the damage it does to the environment and the people of that region. The building sector is one of the largest consumers and polluters in the US.

With any major project, research or otherwise, the best thing you can do is start early. I always set weekly goals, but you should work with whatever schedule suits you best. If you can work on something a little bit all the time, you will accomplish your goal with no huge stress at the end. This will also allow you to have periodic checks by professors and peers to ensure quality and clarity.

OU Major: MicrobiologyResearch Mentor: Marc LibaultDescribe your undergraduate research or creative project:

The ability for plants to grow under drought conditions is becoming increasingly important. As climate change leads to more frequent occurrence of droughts, crops must be able to withstand these conditions. Sorghum, in addition to being a major food crop in the U.S., is adapted to grow in water-limited areas, and is therefore a good model for studying drought-tolerant phenotypes. The root system is specialized in the uptake of water, so we characterized morphological root traits important in the ability of a plant to adapt to drought conditions. We studied these traits by crossing drought-resistant and drought-susceptible sorghum parental lines to create recombinant lines with a mixture of these traits. Using these recombinants, we evaluated changes to the root system in response to both drought and well-watered conditions. These phenotypic adaptations to drought stress can be linked to specific genes and used to create drought-tolerant crops.

Throughout my time working on this project, the most important thing I have learned is how to figure out solutions when things don't go as expected. While it can be frustrating, some of the best learning comes from figuring out a different approach when something doesn't work the first time. I would say that any undergraduates interested in research should seek out any opportunities to get involved, as it is a valuable learning experience and a good way to figure out your interests.

OU Major: Political Science, co-enrolled in an accelerated Masters of Public AdministrationResearch Mentor: Dr. Ana Bracic, Dr. Cindy Simon RosenthalDescribe your undergraduate research or creative project:

Research suggests that women and men legislators differ in their framing of policy issues. In studies comparing attitudes and vocabulary usage, women tended to conceptualize policy issues differently than their male colleagues. Kathlene Lyn designed an experiment testing this theory, finding that women and men legislators in Colorado considered the origins of and solutions to crime differently. Through my research, I hoped to test the generalizability of this study, by applying this hypothesis to the topic of economic opportunity through the policy issue of payday-loans. Based on existing evidence, I hypothesized that women legislators would refer to economic issues from a contextual standpoint, in this case using situational words to describe the high number of payday-loan borrowers. In contrast, I hypothesize that male legislators use language more instrumental in nature; alluding to the idea that people are autonomous individuals responsible for their own successes and failures.

My experiences with this research project opened me up to a new set of skills and experiences that I know will be valuable when applying for graduate school. I would advise students to get started on a research project as early as possible in your academic career. Figure out what you're passionate about, and find a mentor in your field.

Fieldworks is an initiative of the School of Visual Arts at the University of Oklahoma that blends research and teaching in an ongoing artistic and art-historical exploration of land use and interpretation in the deserts of the western United States. Open-ended, collaborative, and transdisciplinary, its participants engage in fieldwork that results in creative, scholarly, and pedagogical outcomes, including exhibitions, publications, and events that explore the changing relationship between humanity and the planet. Among its core elements is a biannual two-week excursion into the field that brings the School’s faculty, students, and staff together to explore a central thematic. For the 2013 Road to Ruscha project, this meant retracing the path that the artist Ed Ruscha traveled to create his seminal 1963 artist’s book Twentysix Gasoline Stations. In 2015, a second group traveled throughout the Sonoran, Mojave, and Great Basin Deserts to investigate earthworks such as...

The Tiger Snail (Anguispira alternata) is an eastern land snail that extends into northeastern Oklahoma. Beyond this range, a large disjunct population occurs in the central Oklahoma (Cleveland and McClain Counties). We assessed possible mechanisms for long-distance dispersal, using timed searches of preferred habitats in woodlands in 19 counties extending westward from the eastern Oklahoma range limit. No snails were found in between historical and disjunct populations. However, empty shells were found in Bryan County (southcentral Oklahoma), washed up along the shoreline of Lake Texoma. These shells originated in the Washita River drainage and were carried downstream to Lake Texoma during floods – indicating that the disjunct population is widely spread (e.g., possibly in Garvin County). Because snails move slowly, the lack of tiger snails between the known and disjunct sites indicates movement via human activities, such as the transport by firewood or the plant trade, rather than...

I analyze a theatrical piece done by Perla de la Rosa that is called "Antígona: las voces que incendian el desierto". This work addresses the violence against the women in Ciudad Juárez, México. According to her text and other articles, I conclude that she adapted Antigone from Sophocles in order to draw attention to the idea that not only is the violence against women a problem, but also that the government is aiding and abetting this violence by denying the women their due justice. I also suggest a solution for the violence, according to Perla de la Rosa's work and related articles.

My research aim is to investigate the representation of femicide in various films and theatrical productions. Femicide is the term used to refer to the period of brutal violence towards women in Juarez, Mexico from 1993 to the early 2000s. Since that time, it has received significant international attention and has become the inspiration of many cinematographic and literary pieces. In order to investigate its representation in contemporary works, I analyzed a selection of documentaries, fiction films, and plays in order to see how each author attempts to convey the topic as well as highlight any underlying messages in relation.

OU Major: Plant BiologyResearch Mentor: Dr. Laura BartleyDescribe your undergraduate research or creative project:

Plants maintain a beneficial symbiosis between their roots and mycorrhizal fungi. Mycorrhizal fungi influence nutrient uptake in plants while increasing tolerance to environmental stresses. I research mycorrhiza in cereal crops, that are critical for producing food, feed, fiber, and chemicals. These uses stem from the high biomass yield of cereal crops which is due to their cell wall, a complex structure containing sugar chains surrounding the cell. Grasses, including cereals, contain an abundance of the compound Ferulic Acid (FA) that crosslinks sugar chains of the cell wall and increase cell wall integrity. Besides decreasing the sugars released from the cell wall, FA crosslinks could act as a physical barrier to mycorrhizal fungi and reducing FA may increase mycorrhizal colonization. Understanding mycorrhiza in cereals might lead to higher efficiency in nutrient uptake and help cereal crops better survive environmental stresses that are becoming more apparent through climate change.

I would say to take advantage of every opportunity that presents itself. When it comes to research, there will be many opportunities that require you to step up and take charge of your path. It’s always better to try new things than look back and regret that you didn’t attempt anything new. Coming in as a freshman, I wanted to just do work for my lab at OU and stay there all the time. Then opportunities presented themselves and next thing I knew I was researching at the University of Arizona then a year later, abroad at Cambridge University in England. When it comes to these opportunities in research, they often always yield good results and provide you a great life experience. Undergraduate research provides you the flexibility to find what you’re passionate about and what you want to pursue in graduate school or in industry. Thus, this is the perfect time to try new things and learn more about yourself. Always believe that you can achieve your goals and trust the process.
