After almost two weeks of rain, the sun shone bright above W.E. Anderson Stadium as the Langston University Class of 2025 processed onto the football field for the 125th Commencement Ceremony, adding to the air of joy and levity that could be felt all over campus.

Cheering, dancing, noisemakers and more could be heard from all over campus as the hundreds of friends and families packed the stand to celebrate their graduates, nearly 70% of whom are the first in their families to earn a college degree. J’Taelii Heath was one of these first-generation students.

But if it weren’t for the encouragement of her family, and the Langston University McCabe Honors Program, she might not have been able to attend university at all.

Heath grew up in Oklahoma City in a family of entrepreneurs. From working with kids to styling hair, her family was involved in a variety of industries, but the business path never interested Heath. She was more interested in STEM, and the idea of entering the medical field had always intrigued her. When she took a health class in high school with a vegan teacher who taught them about different types of healthy lifestyles, she decided she wanted to go to school to study osteopathic medicine.

“It was just something that stuck with me,” Heath said. “I just wanted to continue to do that research and find a different outlet besides (the plant-based diet).”

Once she knew she wanted to study medicine, Heath knew she needed to get her bachelor’s degree first. As the oldest of five kids, it was also important to her to show her siblings that college was a viable option they could also choose.

As she began looking into schools, she knew wherever she enrolled needed to be affordable, have a good biology program and be close enough to home that she could still be a part of her younger siblings’ lives.

Langston University fit the bill.

Heath earned a McCabe Scholarship, which paid for her tuition, room and board, and entered the Lion Pride as a biology major.J'Taelii Heath holds certificate

“It just offered the opportunity for me to stay close to family and be able to afford it, of course, with a full ride scholarship,” Heath said. “That was the first step, being in the honors program, having my school paid for, especially coming from a low-income household where I’m the oldest and a first-generation college student.”

When she got to campus, Heath sought out Dr. Byron Quinn. A biology professor and accomplished researcher, Dr. Quinn is a mentor to many LU students, and Heath knew she wanted to join his lab. Dr. Quinn was happy to have her.

In Dr. Quinn’s lab, Heath learned how to properly conduct research. She learned how to handle different types of equipment and run simple experiments. She was eager to learn and a quick study, and she impressed Dr. Quinn. He helped her apply for an internship with the Oklahoma Medical Research Foundation (OMRF) as one of the first OMRF-LU Scholars.

During her OMRF internship, Heath helped design and conduct an experiment using black pepper, more specifically a compound called piperin, as a treatment for multiple sclerosis. Her goal was to find a more natural alternative treatment for the disease that didn’t rely solely on drugs. To her delight, the experiment was a success.

Heath continued working with OMRF as an LU Scholar after the internship was over, and she also began to help out more in Dr. Quinn’s lab. Heath found she really enjoyed research, so she decided to apply to OK-LSAMP, a statewide program that provides financial assistance to student researchers so they can present their research at professional conferences and conventions.

Over the course of her time at Langston University, with the assistance of her professors and the OK-LSAMP program, Heath has presented her research 15 times at local and national conferences.

“It has helped me see the world differently,” Heath said. “Traveling from state to state, people do things differently… It also helped me learn public speaking skills. I’ve always been very shy and not prone to want to go talk to people.”

Heath has also had the opportunity to assist with NASA research at Langston University, specifically with a project focused on studying how to keep astronauts’ immune cells active while in space conditions. Currently, the LU research team is preparing samples to be sent to the International Space Station. Heath will be a part of the team that will analyze the samples upon their return to Earth.

OK-LSAMP manager and associate professor of chemistry at Langston University, Dr. Lindsay Davis, immediately recognized Heath’s potential as an excellent student from the moment she met her in 2021.

Since then, Dr. Davis has seen Heath grow into the inquisitive student she is today. A student who always seeks to improve herself. A student who seeks new opportunities wherever she can find them.

“(Heath) is always wondering how to improve,” Dr. Davis said. “I don’t know if she really realizes her power. (Her power) is evident by all of her accolades. It’s evident. I wish she would seek that part of herself more. But that’s part of being a young Black scientist; you just kind of do it, and she’s doing it.”

As Heath stood to be recognized as a winner of the Outstanding Senior Leader Award during the commencement ceremony, she beamed with power. The award is earned by graduating seniors who go above and beyond throughout their college career in their commitment to leadership, academics, campus involvement, community service and exemplary character, all of which embodied her journey at Langston University.

Eventually her name was called to receive her diploma, and she strolled up the ramp and onto the commencement stage, taking a photo with President Ruth Ray Jackson and shaking hands with the members of the dais.

She walked off the opposite side ramp the first member of her family to graduate college.

“I just want to be the outlet for my siblings, to be that extra guidance to a different path for our family and for generations to follow,” Heath said. “There is a different path that is an option for us.” 

From Theory to Practice: Langston University Celebrates 25th Annual Research Day

By Jet Turner, Assistant Director of Communications

Langston University held its 25th Annual Research Day on April 18, 2025. Research Day includes various disciplines, majors and students. Whether you are a biology or chemistry student, psychology student or even a computer science student, you are welcome to participate in Research Day.

Research Day aims to help students understand the practical applications of their learning. It shows students how their knowledge can serve society and provides an opportunity to demonstrate their problem solving and articulation skills. It also allows students to build their resumes, prepare for internships and graduate school applications, among many other skills.

“It’s the value added,” said Dr. John K. Coleman, Interim Dean of the College of Arts and Sciences. “Once you get a culture where students (are presenting their research), you look at the student and you just see the product. Now they are starting to learn why they’re learning these theories and why they learn these concepts, and then what you can actually do with it and how you can help society. You’re here to learn, but you leave to serve. So how do you use what you’re learning? This is the part that teaches you how you use what you’re learning to serve society.”

Dr. Lindsay Davis, associate professor of chemistry, participated in the 13th Research Day when she was a student at LU.

Despite her fear and hesitation to present her research, she was well prepared and supported.

“Ultimately, Research Day gave me the confidence that I needed to pursue graduate school and to make these presentations a norm for me,” Dr. Davis said. “I was so scared of public speaking, and now it’s easy.

“So, Research Day definitely helps with their communication skills. But most importantly, I think it allows them to be a scientist, to communicate through research and to really achieve their goals.”

This year over 20 students participated in Research Day. 

 

Josiah Grayson – Selection of Undergraduate Degree Major Among College Students

Senior, Computer Science Major

Josiah Grayson’s research explored the psychological and social factors influencing how college students, especially those at Historically Black Colleges and Universities (HBCUs), choose their academic majors.

Grayson’s studies revealed personal interest is the most important factor when a prospective student selects a major, which contradicts his hypothesis that financial considerations would be at the forefront of their decision-making process.

Grayson highlights that student interests are often “shaped by what they have been exposed to,” meaning individuals are more likely to pursue careers and majors they have seen modeled in their communities. For Black students specifically, this means decisions are “shaped by survival, legacy and representation.”

“Institutional culture and climate impacts persistence,” Grayson said. “What goes on at the university and then specifically in the department, how they teach the information, how they work with the students. Is there tutoring? These things highly impact whether or not somebody is actually going to finish their degree.”

Financial status, according to Grayson, still plays a significant role in a student’s decision in what major they select, even if it isn’t the primary driving force. Grayson notes that students from a lower socioeconomic status tend to be more risk-averse, often choosing a “more stable” career path, while students from higher socioeconomic backgrounds have more flexibility to pursue less conventional majors, if they so choose.

 

Kimbree Layton – Studying the Relationship Between Mental Health, Emotional Well-Being and Academic Well-Being Among College Athletes

Senior, Psychology Major

Kimbree Layton conducted a comprehensive study examining the relationship between mental health, emotional well-being and academic well-being among collegiate athletes at Langston University. Her research focused specifically on anxiety, depression and stress levels among student athletes.

The study employed a multi-scale survey approach, utilizing four different psychological assessment tools. Layton was able to collect data from 15 of Langston University’s student athletes, all of whom were female.

Findings revealed that Langston University student athletes generally demonstrated positive mental health indicators, showing no significant signs of depression, anxiety or stress.

“(The student athletes) think highly of professional help and seeking it when it is necessary,” Layton said.

Layton’s research highlighted several critical factors influencing student athlete mental health, including “the importance of their relationships” with coaches, professors and family. Modern student athletes must overcome a tough emotional landscape, and many challenge the stigma that they should always be “very mentally tough” and not show emotions.

While the study provides valuable insights, Layton recognized limitations in her research, including the small sample size and the use of somewhat dated psychological assessment scales. She recommended future research should “examine what relationships between scales and demographics” exist and potentially explore the impact of teammates on mental health, a dimension not fully explored in this current study.

 

Reginald M. Archibald II – Artificial Intelligence Biases in Healthcare

Senior, Computer Science Major

Reginald Archibald II explored the critical issue of artificial intelligence (AI) bias in healthcare, highlighting how AI models can perpetuate systemic inequalities.

Archibald’s research uncovered six types of bias in healthcare AI models: implicit, selection, measurement, confounding, temporal and algorithm bias.

An example pointed to in this research is the dermatology AI tool developed by Stanford University, which was trained predominantly on images of lighter-skinned individuals. This could have a significant negative impact on patients who have a darker skin complexation.

“When you go in and they’re trying to detect for skin cancer, oftentimes they’re not able to find it, and they might (misdiagnose) you,” Archibald said.

Several other real-world scenarios demonstrate the potential harm of biased AI. During the COVID-19 pandemic, pulse oximeters were found to miss conditions in Black patients three times more often than in other races. Another study revealed an AI algorithm that based healthcare decisions on costs that systematically undervalued Black patients’ health needs.

To address these critical issues, Archibald proposes multiple solutions. These include conducting bias audits before AI deployment, training healthcare professionals on AI decision-making processes and incorporating synthetic data to improve representation.

He emphasizes the importance of diversity in AI development, stating that diverse team members can provide “ethical background knowledge about their race, their gender, their age group and their economic status.”
