Joseph LeSueur’s interest in biomedical engineering began in high school, during an
internship with the BioRobotics research team at the Cleveland Clinic.
“I was introduced to mechanical testing of cadaveric tissues,” the 2020 Trine University
graduate said. “This sparked an interest in how understanding the mechanics of the
human body can be translated to patient care by influencing surgical decisions and
prescribing rehabilitation.”
He is still interested in injury biomechanics and the failure thresholds of biological tissue. His thesis for his Ph.D., which he is earning through a joint program from Marquette University
and the Medical College of Wisconsin, focuses on understanding the mechanical behavior of skin during puncture and ballistic impact.
“Our work focuses on understanding the fundamental mechanics of skin during high rate
impact of small fragments,” he said. “This experimental work is the foundation for
development of finite element models which may be used to simulate multivariate impacts
for advancement of improved protective clothing.”
Joseph jumped at the opportunity.
“In studying ballistic impact, we found that the velocity required to penetrate skin
was a function of the projectile's sectional density. For puncture of isolated skin,
we quantified differences in failure thresholds based on impactor size, loading rate,
and thickness of the skin,” he said. “I also used digital image correlation and histology
to determine directional dependency in strain and damage to collagen fibers in the
dermis, respectively.”
Golf and BME
Joseph’s internship at the Cleveland Clinic gave him an idea of what he wanted to
do in life, and it helped him narrow down the deciding factors in his college choice.
“My college decision had two primary criteria,” he said. “The opportunities to play
golf and study biomedical engineering.”
After visiting several schools, Trine University became his obvious choice.
“Seeing (and playing) the Zollner Golf Course on campus surrounded by the amazing
student apartments [was great], but the decision was undoubtedly clear after touring
the labs and meeting Dr. Gerschutz and other fantastic BME (biomedical engineering)
faculty,” he said.
Joseph’s experience at Trine did a great job preparing him for Ph.D. research.
“Within the BME curriculum, engineering faculty at Trine provided high-quality education
and laboratory experiences (from welding to tissue culture to 3D kinematics of human
movement), which enabled a straightforward transition to graduate-level courses,”
he said. “However, the greatest advantage of my Trine education was developing confidence
and excellence in scientific writing and presenting, which was possible with small
class sizes and faculty that emphasized personal development.”
Joseph didn’t care that Trine was a small school. He actually enjoyed it.
“Even at a small school, I was still able to gain research experience in human biomechanics,
which highly motivated my decision to pursue graduate school,” he said.
Joseph’s future plans are similar to his current ones.
“As my career progresses, I plan to continue studying biomechanics to prevent and
rehabilitate injury, whether that is in industry, academia or entrepreneurship,” he
said. “I am newly married to Jenna (Gales), who graduated with her Doctorate in Physical
Therapy from Trine's 3+3 DPT program, and I look forward to a wonderful life of marriage,
family and maybe even research collaboration!”
