Dr. Sandy Simon Halliburton '94 
has grown accustomed to succeeding in seemingly strange situations.
After 
graduating summa cum laude from Hendrix with a physics degree, Halliburton went 
immediately to Vanderbilt University, where she earned her master's degree and 
doctorate in biomedical engineering. 
"I was very nervous majoring in 
biomedical engineering at an elite university," said Halliburton, whose graduate 
classmates held engineering degrees from top-ranked schools such as Duke 
University and Johns Hopkins University.
Though the head of the biomedical 
engineering program knew of Hendrix and its reputation, Halliburton was offered 
only a 50 percent tuition remission for graduate school, which is considered 
"one step above rejection" in the field, she said.
Fortunately, she was 
awarded a fellowship from the National Science Foundation, which included a 
stipend and three years of paid tuition expenses.
"I can credit [Hendrix 
physics professor] Bob Dunn for that," said Halliburton, who worked for Dr. Dunn 
as a research assistant. "He encouraged me to apply and helped me put together a 
winning application."
"That award obviously got me a little recognition when 
I started, but I still had a bit of an inferiority complex, coupled with being a 
physics major jumping fields and types of institutions," she said. "But by the 
end of the first year, I knew it was a great fit." 
She also received a 
training grant from the National Institutes of Health during her time at 
Vanderbilt, where she was a member of Tau Beta Pi, the engineering honor 
society.
Her master's thesis and doctoral dissertation focused on aspects of 
magnetic resonance imaging (MRI). This research, coupled with the emerging 
technology of cardiac computed tomography (CT), gave shape to her post-graduate 
career.
Since 1999, Halliburton has worked as a cardiac imaging scientist at 
the Cleveland Clinic in Cleveland, Ohio, where she develops and implements novel 
and state-of-the-art CT imaging and post-processing techniques for clinical 
cardiac studies. She also holds staff appointments at Cleveland Clinic in the 
cardiovascular medicine and biomedical engineering departments and serves as an 
adjunct professor in the biomedical and chemical engineering department of 
Cleveland State University.
Just as she felt in graduate school, Halliburton 
found herself to be unique in her new environment.
"I'm a technical person in 
a sea of clinical people," she said. "It's medically trained people (e.g., 
radiologists, cardiologists, nurses) and me, a scientist."
Halliburton helps 
medical teams understand the technical aspects of the imaging equipment so that 
physicians can get more diagnostic value out of cardiac CT images.
"As 
technology has evolved with new machine hardware and software, my role is to 
help integrate that into the clinical environment," she said.
Her primary 
research areas include radiation dose optimization, contrast agent dose 
optimization, dual energy CT, iterative image reconstruction, atherosclerotic 
plaque characterization, and coronary calcium scoring. 
"Our research is very 
close to clinical application," she said, adding that her "army" of researchers 
generally includes one Ph.D. student and maybe a couple of research fellows. 
"Our interest is in some particular challenge in the clinical environment at the 
moment."
Halliburton has become the go-to person for education on new CT 
technology. She routinely gives "technical talks" to cardiologists and 
radiologists at medical conferences around the world.
"I speak all the time," 
she said. "My personal niche is the ability to communicate. It's what's given me 
a career ... As a liaison between the CT industry and physicians, I take 
complicated physics and engineering concepts and distill that down to language 
that clinicians with different training can understand. That's what I do."
Halliburton credits Hendrix with honing her communication skills.
"The thing 
I value most from Hendrix is my ability to write," she said. "I didn't think 
about it at the time, but I was writing mini-papers in Calculus I. Lab reports 
were writing assignments." 
"I advise students writing dissertations. They're 
great engineering students, but their writing is often disappointing," she said. 
"There's an idea that engineers can't write, and that's supposed to be 
acceptable in some way? Not to me."
"If I zone in on one thing that has 
helped me in my career, it's the ability to communicate and take complicated 
things and make them understandable," she said. "If you can't communicate what 
you learn, what you discover, you might as well not even do the work."
Dr. 
Halliburton and her husband, Michael Halliburton '94, live in Shaker Heights, 
Ohio, with their two children.
