Daniel A. Hammer and Miriam Wattenbarger to Offer Summer Course on COVID-19

Daniel A. Hammer and Miriam Wattenbarger

As researchers hunt for a solution to the coronavirus outbreak, Daniel A. Hammer, Alfred G. and Meta A. Ennis Professor in Bioengineering and in Chemical and Biomolecular Engineering (CBE), is bringing lessons from the fight for a vaccine to the classroom.

Hammer will offer a course on COVID-19 and the coronavirus pandemic during Penn’s Summer II session, which will be held online this year. The course will be co-taught with Miriam Wattenbarger, senior lecturer in CBE.

The course, “Biotechnology, Immunology, and COVID-19,” will culminate with a case study of the coronavirus pandemic including the types of drugs proposed and their mechanism of action, as well as the process of vaccine development.

“Obviously, the pandemic has been a life-altering event, causing an immense dislocation for everyone in our community, especially the students. Between me and Miriam, who has been trumpeting the importance of vaccines for some time in her graduate-level CBE courses, we have the expertise to inform students about this disease and how we might combat it,” says Hammer.

For more than ten years, Wattenbarger has run courses and labs focused on drug delivery and biotechnology, key elements of the vaccine development process.

“I invite both researchers and industry speakers to meet with my students,” Wattenbarger says, “so that they learn the crucial role engineers play in both vaccine development and manufacturing.”

Beyond studying the interactions between the immune system and viruses — including HIV, influenza, adenovirus and coronavirus — students will cover a variety of biotechnological techniques relevant to tracking and defending against them, including recombinant DNA technology, polymerase chain reaction, DNA sequencing, gene therapy, CRISPR-Cas9 editing, drug discovery, small molecule inhibitors, vaccines and the clinical trial process.

Students will also learn the mathematical principles used to quantify biomolecular interactions, as well as those found behind simple epidemiological models and methods for making and purifying drugs and vaccines.

“We all have to contribute in the ways that we can. Having taught biotechnology to freshmen for the past decade, this is something that I can do that can both inform and build community,” says Hammer. “Never has it been more important to have an informed and scientifically literate community that can fight this or any future pandemic.”

Bioengineering News Round-Up (April 2020)

How to Heal Chronic Wounds with “Smart” Bandages

Some medical conditions, like diabetes or limb amputation, have the potential to result in wounds that never heal, affecting patients for the rest of their lives. Though normal wound-healing processes are relatively understood by medical professionals, the complications that can lead to chronic non-healing wounds are often varied and complex, creating a gap in successful treatments. But biomedical engineering faculty from the University of Connecticut want to change that.

Ali Tamayol, Ph.D., an Associate Professor in UConn’s Biomedical Engineering Department, developed what he’s calling a “smart” bandage in collaboration with researchers from the University of Nebraska-Lincoln and Harvard Medical School. The bandage, paired with a smartphone platform, has the ability to deliver medications to the wound via wirelessly controlled mini needles. The minimally invasive device thus allows doctors to control medication dosages for wounds without the patient even having to come in for an appointment. Early tests of the device on mice showed success in wound-healing processes, and Tamayol hopes that soon, the technology will be able to do the same for humans.

A New Patch Could Fix Broken Hearts

Heart disease is by far one of the most common medical conditions in the world, and has a high risk of morbidity. While some efforts in tissue engineering have sought to resolve cardiac tissue damage, they often require the use of existing heart cells, which can introduce a variety of complications to its integration into the human body. So, a group of bioengineers at Trinity College in Dublin sought to eliminate the need for cells by creating a patch that mimics both the mechanical and electrical properties of cardiac tissue.

Using thermoelastic polymers, the engineers, led by Ussher Assistant Professor in Biomedical Engineering Michael Monaghan, Ph.D., created a patch that could withstand multiple rounds of stretching and exhibited elasticity: two of the biggest challenges in designing synthetic cardiac tissues. With the desired mechanical properties working, the team then coated the patches with an electroconductive polymer that would allow for the necessary electrical signaling of cardiac tissue without decreasing cell compatibility in the patch. So far, the patch has demonstrated success in both mechanical and electrical behaviors in ex vivo models, suggesting promise that it might be able to work in the human body, too.

3-D Printing a New Tissue Engineering Scaffold

While successful tissue engineering innovations often hold tremendous promise for advances in personalized medicine and regeneration, creating the right scaffold for cells to grow on either before or after implantation into the body can be tricky. One common approach is to use 3-D printers to extrude scaffolds into customizable shapes. But the problem is that not all scaffold materials that are best for the body will hold up their structure in the 3-D printing process.

A team of biomedical engineers at Rutgers University led by Chair of Biomedical Engineering David I. Schreiber, Ph.D., hopes to apply the use of hyaluronic acid — a common natural molecule throughout the human body — in conjunction with polyethylene glycol to create a gel-like scaffold. The hope is that the polyethylene glycol will improve the scaffold’s durability, as using hyaluronic acid alone creates a substance that is often too weak for tissue engineering use. Envisioning this gel-like scaffold as a sort of ink cartridge, the engineers hope that they can create a platform that’s customizable for a variety of different cells that require different mechanical properties to survive. Notably, this new approach can specifically control both the stiffness and the ligands of the scaffold, tailoring it to a number of tissue engineering applications.

A New Portable Chip Can Track Wide Ranges of Brain Activity

Understanding the workings of the human brain is no small feat, and neuroscience still has a long way to go. While recent technology in brain probes and imaging allows for better understanding of the organ than ever before, that technology often requires immense amounts of wires and stationary attachments, limiting the scope of brain activity that can be studied. The answer to this problem? Figure out a way to implant a portable probe into the brain to monitor its everyday signaling pathways.

That’s exactly what researchers from the University of Arizona, George Washington University, and Northwestern University set out to do. Together, they created a small, wireless, and battery-free device that can monitor brain activity by using light. The light-sensing works by first tinting some neurons with a dye that can change its brightness according to neuronal activity levels. Instead of using a battery, the device relies on energy from oscillating magnetic fields that it can pick up with a miniature antenna. Led in part by the University of Arizona’s Gutruf Lab, the new device holds promise for better understanding how complex brain conditions like Alzheimer’s and Parkinson’s might work, as well as what the mechanisms of some mental health conditions look like, too.

People & Places

Each year, the National Academy of Engineering (NAE) elects new members in what is considered one of the highest professional honors in engineering. This year, NAE elected 87 new members and 18 international members, including a former Penn faculty member and alumna Susan S. Margulies, Ph.D. Now a professor of Biomedical Engineering at Georgia Tech and Emory University, Margulies was recognized by the NAE for her contributions to “elaborating the traumatic injury thresholds of brain and lung in terms of structure-function mechanisms.” Congratulations, Dr. Margulies!

Nimmi Ramanujam, Ph.D., a Distinguished Professor of Bioengineering at Duke University, was recently announced as having one of the highest-scoring proposals for the MacArthur Foundation’s 100&Change competition for her proposal “Women-Inspired Strategies for Health (WISH): A Revolution Against Cervical Cancer.” Dr. Ramanujam’s proposal, which will enter the next round of competition for the grant, focuses on closing the cervical cancer inequity gap by creating a new model of women-centered healthcare.

Blood Test May Help Doctors Catch Pancreatic Cancer Early

A blood test may be able to detect the most common form of pancreatic cancer while it is still in its early stages while also helping doctors accurately stage a patient’s disease and guide them to the appropriate treatment. A multidisciplinary study found the test—known as a liquid biopsy—was more accurate at detecting disease in a blinded study than any other known biomarker alone, and was also more accurate at staging disease than imaging is capable of alone. The team, which includes researchers from the Perelman School of Medicine, the Abramson Cancer Center, and the School of Engineering and Applied Science, published their findings in Clinical Cancer Research, a journal of the American Association for Cancer Research.

Pancreatic ductal adenocarcinoma (PDAC), the most common form of pancreatic cancer, is the third leading cause of cancer deaths. The overall five-year survival rate is just 9%, and most patients live less than one year following their diagnosis. One of the biggest challenges is catching the disease before it has progressed or spread. If the disease is caught early, patients may be candidates for surgery to remove the cancer, which can be curative. For locally advanced patients—meaning patients whose cancer has not spread beyond the pancreas but who are not candidates for surgery based on the size or location of the tumor—treatment involves three months of systemic therapy like chemo or radiation, then reassessing to see if surgery is an option. For patients whose disease has spread, there are currently no curative treatment options.

“Right now, the majority of patients who are diagnosed already have metastatic disease, so there is a critical need for a test that can not only detect the disease earlier but also accurately tell us who might be at a point where we can direct them to a potentially curative treatment,” says the study’s co-senior author Erica L. Carpenter, director of the Liquid Biopsy Laboratory and a research assistant professor of medicine. The study’s other co-senior author is David Issadore, an associate professor of bioengineering and electrical and systems engineering.

Dr. Danielle Bassett and Dr. Jason Burdick Named to Highly Cited Researchers List

by Sophie Burkholder

One way to measure the success or influence of a researcher is to consider how many times they’re cited by other researchers. Every published paper requires a reference section listing relevant earlier papers, and the Web of Science Group keeps track of how many times different authors are cited over the course of a year.

Danielle Bassett, Ph.D.

In 2019, two members of the Penn Bioengineering department, Jason Burdick, Ph.D., and Danielle Bassett, Ph.D., were named Highly Cited Researchers, indicating that each of them placed within the top 1% of citations in their field based on the Web of Science’s index. For the past year, only 6,300 researchers were recognized with this honor, a number that makes up a mere 0.1% of researchers worldwide. Bassett’s lab looks at the use of knowledge, brain, and dynamic networks to understand bioengineering problems at a systems-level analysis, while Burdick’s lab focuses on advancements in tissue engineering through polymer design and development.

Robert D. Bent Chair
Jason Burdick, PhD

Burdick’s and Bassett’s naming to the list of Highly Cited Researchers demonstrates that their research had an outsized influence over current work in the field of bioengineering in the last year, and that new innovations continue to be developed from foundations these two Penn researchers created. To be included among such a small percentage of researchers worldwide indicates that Bassett and Burdick are sources of great impact and influence in bioengineering advancements today.
