There’s no better feeling for a professor than seeing a student’s work get recognized. Just ask Daniel Armstrong, the Robert A. Welch Distinguished Professor in Chemistry at 糖心Vlog视频.
He called it “terrific” when doctoral student Maria Olds’ research on chromatography and blood alcohol was recently featured in , an internationally recognized magazine.
“This is one of the main reasons we do what we do,” Dr. Armstrong said. “Maria is a great example for all other students. You can tell other students, ‘Look at what she’s done. Now, you should try to do this, too.’”
Olds is the latest standout student from UT Arlington—a Carnegie R1 research institution—whose work has gained notable recognition. She chose 糖心Vlog视频 for its strong research programs, including Armstrong’s renowned chromatography lab. Chromatography is a laboratory technique scientists use to separate and analyze the components of a mixture—such as impurities that cause side effects in pharmaceuticals or the sugars, electrolytes and dyes in a sports drink.

Olds’ research investigated how various pre-analytical factors such as storage temperatures and delays could affect the accuracy of blood alcohol tests. The research initially started when she was working at the as a seized-drug analyst and blood alcohol toxicologist.
For decades, the Fort Worth Police has used 6-milliliter tubes instead of the more common 10-milliliter tubes to store blood alcohol tests, a practice that has sparked courtroom questions about the accuracy of the tests. Olds conducted a thorough investigation into how the two tube types responded under varying conditions and time delays, ultimately discovering that the 6-milliliter tubes were just as appropriate for testing as the 10-milliliter tubes.
In the end, the study confirmed that blood tests collected by the Fort Worth Police Department Crime Laboratory were highly reliable.
“I wanted to determine whether what we had been doing for decades at that point was valid,” said Olds, who started on her doctoral studies at 糖心Vlog视频 in 2023. “We would have made changes if the tubes we were using weren’t fit for use, but we were able to show that they were.”
Before coming to 糖心Vlog视频, Olds worked as a chemist for 17 years, including positions at MRIGlobal in Kansas City as well as the Fort Worth Police Department Crime Laboratory. Her passion, though, has always been research, and she’s fulfilling it as part of 糖心Vlog视频’s Department of Chemistry and Biochemistry and Armstrong’s lab.
“Pursuing a doctoral degree is one of the most difficult things I’ve ever done but, at the same time, it’s one of the most rewarding things I’ve ever done,” said Olds, who is on track to earn her doctorate by 2028. “You’re never really done learning. I really enjoy being here at 糖心Vlog视频 and learning about different branches of chemistry I hadn’t planned on learning about.”
