Students present posters at the annual Biomechanics Research Symposium.

Biomechanical engineering research

Research on gait, osteoarthritis, orthopedics, other topics in biomechanics highlighted


10:10 a.m., May 14, 2015--Close to 100 participants turned out for the 12th annual Biomechanics Research Symposium at the University of Delaware on Friday, May 8.

Held at UD’s Science, Technology and Advanced Research (STAR) Campus, the event was hosted by UD’s Center for Biomechanical Engineering Research

Research Stories

Chronic wounds

UD's Millicent Sullivan and Kristi Kiick have received a $1.4 million grant from the National Institutes of Health for research that could provide a new approach to the treatment of chronic wounds.

Prof. Heck's legacy

The American Chemical Society is highlighting the legacy of the late Nobel laureate Richard Heck, the Willis F. Harrington Professor Emeritus of Chemistry at the University of Delaware with a digital tribute on its publications website.

The program included 10 podium presentations and 29 posters on topics including human motion after injury and stroke, the mechanics of musculoskeletal tissues, the development of devices and technologies for measuring and correcting human motion, and the transport and effects of drug therapies on cartilage and bone.

Dawn Elliott, chair of biomedical engineering at UD, delivered the keynote address. Borrowing heavily from a quote by British humorist Douglas Adams, Elliott titled her talk “Studying Tissue Biomechanics is Like Taking Apart a Cat to See How it Works: You Get a Non-working Cat.”

Elliott’s research focuses on the changes that occur in load-bearing fibrous tissues such as the intervertebral disc in the spine and the meniscus in the knee during development, growth and aging, as well as after injury and therapeutic interventions. 

“It’s challenging to measure the stresses and strains on tissues without disrupting the tissues and thereby altering the measurements,” she said. 

She shared with the audience highlights of her multi-scale approach, which spans from the entire joint level to the tissue scale and the micro scale. Her work integrates mechanical testing, mathematical modeling, and multi-scale imaging.

Using MRI-based biomechanics and finite element modeling, Elliott and her team are getting closer to seeing “how the cat works” without disabling it.

Student awards

Four awards, sponsored by the Delaware Rehabilitation Institute, were awarded to student researchers, two each for podium presentations and posters.

Podium presentations

  • First place: Ashutosh Parajuli, “A Cross-Sectional Age-Wise Assessment of Morphology and Bone Formation in Perlecan-Deficient Mice”
  • Second place: Michael David, “Detailed Quantification of Early Structural Joint Changes in the Murine Destabilized Medial Meniscus Model of Post-Traumatic Osteoarthritis”

Poster presentations

  • First place: Yilu Zhou, “Bisphosphonate Rescued Articular Cartilage From Trauma Damage
  • Second place: Duanyi Wei, “Human-Exoskeleton Hybrid Model To Produce Stable Gait Through Inter-Limb Coordination”

About the symposium

The event was organized by CBER director Michael Santare and Elaine Nelson. Student committee members included Andrea DiTrani, Paula-Marie Ferrara, Danielle Gerstman, Chris Henderson, Kathleen Madara, Jackie Palmer, Alex Razzook, and Aaron Struminger.

About the Center for Biomechanical Engineering Research

CBER is an interdisciplinary center whose mission is to provide engineering science and clinical technology to reduce the impact of disease on the everyday life of individuals. For over 20 years CBER has encouraged cross-disciplinary research across various academic departments at the University of Delaware including Mechanical Engineering, Physical Therapy, Biomedical Engineering, Biological Sciences and Kinesiology and Applied Physiology.

Over the past year, CBER has focused effort on helping to bridge the gap between academia and industry by working closely with the Interdisciplinary Senior Design Capstone Course in the College of Engineering where real life problems are being studied and solved.
