By Scott Gordon When Arjun Seshadri decided to study engineering, he wasn’t necessarily thinking about medical applications. That changed when he discovered the UW-Madison Lab for Molecular Scale Engineering. Before his freshman year was over, he became a research assistant in the lab under former Electrical and Computer Engineering Professor Robert Blick and his graduate [...]

With approximately 22,000 diagnoses annually in the United States, ovarian cancer isn’t among the most commonly occurring cancers. Yet, the mortality rate for women who have ovarian cancer hovers above 60 percent. For Pamela Kreeger (pictured), an assistant professor of biomedical engineering, that number is needlessly high. Kreeger is among a group of exceptionally forward-thinking [...]

Mechanical Engineering Professor Lih-Sheng (Tom) Turng has a simple office demonstration of how shape-memory polymers work. He takes the material, which is formed into a compact flower bud, drops the bud in a cup of warm water, and voila: A daisy slowly blooms. A significant materials research advance by Turng and colleagues may help translate [...]

It’s 1 a.m. and heavy fog cover has caused a terrible accident on the Interstate. A highly trained medical team climbs aboard the medevac chopper and a highly trained pilot flies the team to the scene. The problem, heading into a potentially life-threatening situation, is that these teams train in isolation and often have competing [...]

Biomedical Engineering Professor Ray Vanderby always thought there was more information in an ultrasound signal than people were using. Vanderby and his students specialize in tissue healing and regeneration in musculo-skeletal tissues—and they can use all the information about damaged tissue they can get. That’s where ultrasound can be an added benefit. “If we’re only [...]

Like many good lab discoveries, this one came about by accident. While trying to engineer healthy heart valves, Biomedical Engineering Associate Professor Kristyn Masters was discouraged that cells her student was culturing were forming nasty-looking nodules. These nodules can be present in disease and made the sample cells impossible to use for their intended purpose. [...]

With $3.27 million from the National Institutes of Health, Pediatrics and Biomedical Engineering Associate Professor Marlowe W. Eldridge and Biomedical Engineering Associate Professor Naomi Chesler will research how bronchopulmonary dysplasia, a common condition in low-birth-weight infants, acts as a predictor of right heart failure in adulthood. Finding such a correlation could greatly inform treatment strategies [...]

Video of workers performing tasks such as assembling a manufactured part or packing boxes could help assess the likelihood that those people will develop common repetitive-motion injuries. Repeatedly performing the same motions and exertions can lead to injuries in which the body suffers strain from even tiny actions—for example, handling small parts, operating a machine [...]

People who tear their anterior cruciate ligament, a ligament in the knee that provides stability to the connection between the tibia and femur, usually must opt for a complete ACL reconstruction with a portion of another ligament. However, about 90 percent of people who undergo reconstructive ACL surgery develop osteoarthritis—knee pain, swelling and stiffness—within 20 [...]

Everything in physics is governed by equations, which can be solved to predict, for example, how grains of sand collide, how a tablecloth falls across a flat surface, or how water flows around obstacles. And as computing power becomes cheaper and more accessible to universities, the potential for research applications with large computers is skyrocketing. [...]

At just 28 percent, the five-year survival rate for women diagnosed with ovarian cancer is much lower than in other cancer cases. And, the disease can easily go unnoticed, making it difficult to find effective treatments. “There are very few symptoms associated with ovarian cancer,” says Biomedical Engineering Associate Professor Paul Campagnola. “When it gets [...]

Stem cells are biological building blocks, the starting point of human life. But without proper direction, they’re not very useful when it comes to treating disease. “If we just take stem cells and inject them into you, they will simply become a cancerous tumor,” says Biomedical Engineering Assistant Professor Randy Ashton.

Understanding how a cell makes a decision in response to a drug or stimuli—to grow, to move, or to die—could give doctors richer insight into why, in many cases, different therapies work for different patients. The key to understanding how cells make these decisions may lie within the network of proteins inside those cells. Using [...]
