As a global community, we are experiencing unprecedented change on what seems like a daily basis. Here in the College of Engineering, we are committed to our educational and research mission. At the same time, many of us also have, as they say, dropped everything and devoted our expertise to help our state, country and world combat the COVID-19 pandemic. Here are some examples of this work.
Grad student helping organize PPE production, COVID response in developing countries
Rebecca Alcock, a recent master’s degree recipient in biomedical engineering and an incoming PhD student in industrial and systems engineering at UW-Madison, is leading a large-scale, United Nations-backed effort to mobilize production of personal protective equipment (PPE) and more in Guatemala and other developing countries around the world amid the COVID-19 pandemic. The project is a collaboration among engineers and other experts at UW-Madison, Marquette University, the University of Colorado Anschutz Medical Campus, Colorado Mesa University, Engineers Without Borders (EWB) and the United Nations Development Programme (UNDP).

New shield couples COVID-19 protection with a clear view of the face
University of Wisconsin-Madison engineers worked with partners from UW Health, Midwest Prototyping and others to create the Badger Shield+, a face shield that provides a full, clear view of the face while still filtering virus particles through surgical fabric that cinches around the wearer’s chin and jawline. Just days after its public “launch” in mid-July, the Badger Shield+ has generated requests from more than 300 organizations from 44 states. Midwest Prototyping is fulfilling orders for the Badger Shield+; however, as is the case for its predecessor, Rodgers says the team plans to make the new version available to manufacturers as open-source design drawings, also.
At the onset of the COVID-19 pandemic in the United States, the team’s focus was on ensuring healthcare professionals in particular had enough personal protective equipment. This time, with the Badger Shield+, engineer Lennon Rodgers, director of the Grainger Engineering Design Innovation Laboratory, or engineering makerspace, at UW-Madison, and colleague Karl Williamson developed a design that not only met the UW Health requirements, but they also sought to broaden its reach.
“Karl and I started working on this two months ago when we saw this wave of public openings,” says Rodgers. “We were starting to think outside the box for PPE that didn’t exist. Most PPE is designed for hospitals; we wanted PPE that members of the public could use as they went about their lives. It’s well suited for schools, and for people who need others to see their mouth or need an alternative PPE solution for various reasons.”

Coughing visualization illustrates the benefits of wearing a good mask
UW–Madison Mechanical Engineering Professor Scott Sanders’ team made a video that demonstrates how droplets from a single cough escape from or remain inside of varying mask styles and materials. While the visualization doesn’t directly track the spread of virus particles, Sanders believes it will help people see a risk that is otherwise invisible.
In his tests, Sanders found that in general, the homemade mask shape most effective at containing droplets is a neck-gaiter-style mask that combines a nose piece with an elastic cord that wearers can toggle to snug the mask to their face. He also has created a video that shows a simple way to sew the neck-gaiter mask using a rectangle of tightly woven fabric, a toggle, cord and metal nose piece.

Model response: Alum helps launch COVID data hub
James Tamplin (BSIE ’06, MSIE ’07) worked with a handful of fellow veterans of the Silicon Valley tech scene to develop CovidActNow.org, a website that tracks, among other data points, each state’s infection rate. The site, which bills itself as “America’s COVID warning system,” drew roughly 8 million visitors in the first week after its March 20 launch.
Early on, the Covid Act Now team created projections for disease spread under several policy approaches, ranging from no restrictions to a full lockdown. States such as Michigan and Kentucky cited the group’s model in announcing their respective stay-at-home orders. “We showed people pretty clearly—which wasn’t being done in late March—what each of these scenarios would mean to the hospital capacity in the local area, and I think it really hit home,” Tamplin says.

Wisconsin’s COVID-19 stay at home order drove changes in state’s traffic volume
Traffic along Wisconsin’s highways had an unprecedented drop and remained well below normal in the weeks since Gov. Tony Evers’ Safer at Home order took effect March 25, 2020. The findings are the result of an ongoing traffic study at the University of Wisconsin-Madison’s Traffic Operations and Safety (TOPS) Laboratory in partnership with the Wisconsin Department of Transportation. Interstate traffic volumes began to decline in the week leading up to the World Health Organization declaration of COVID-19 as a global pandemic on March 12, 2020, and a U.S. federal emergency declaration the next day.
The pandemic’s unprecedented circumstances afforded David Noyce, a professor of civil and environmental engineering and director of the TOPS Lab, and researcher Jon Riehl an opportunity to study real-world traffic pattern shifts that are typically only theoretical. Observing real-world performance with reduced volumes on traditionally busy highways can allow engineers to better understand traffic flow compared to predictive computer models, and then pinpoint jam points on highways. “With the reduced traffic volumes, we can now more precisely understand different highway segments’ performance characteristics and compare this to the theoretical values used during highway planning and construction,” Riehl says. “Traffic data like this provides the opportunity to tune the empirical equations we use in highway design and to improve our performance models—which ultimately leads to improvement in highway design and traffic engineering.”

Badger Talks video: A look at reopening after lockdown
Risk analyst Vicki Bier, a professor of industrial and systems engineering, shares insight about the decision-making process that goes into how to reopen a community after quarantine. There may be an inclination to hurry, with so many people eager for their lives to return to normal, but there are good reasons for moving slowly, Bier says.
Schauer leads COVID-19 testing efforts at WSLH
As Wisconsin faces unique challenges prompted by the COVID-19 pandemic, a University of Wisconsin-Madison environmental engineering professor has helped a critical testing lab rise to the challenge. James Schauer, a professor of civil and environmental engineering at UW-Madison, also is director of the Wisconsin State Laboratory of Hygiene (WSLH), which has played a leading role in the state’s testing efforts during the pandemic.
Schauer holds a unique position as both an air pollution expert and as a leader in the state’s response to the pandemic. COVID-19, as a primarily respiratory disease, crosses boundaries from infectious disease research to some of the challenges facing air pollution researchers, such as air filter efficacy for keeping out contaminants. In part, that relates to the relatively new U.S. concept of wearing masks—something Schauer predicts will become more common long-term as COVID-19 ebbs and surges in the population.

UW-Madison faculty, students help create COVID-19 app for Wisconsinites
COVID-19 Wisconsin Connect, a free desktop and mobile app that provides accurate information, social support and helpful resources to Wisconsinites, launched on May 4, 2020. The Center for Health Enhancement Systems Studies (CHESS), based in the University of Wisconsin–Madison Department of Industrial and Systems Engineering, developed the app in partnership with government, academic, medical, business and community organizations statewide. The desktop app can be accessed at www.covid19wisconsinconnect.org; the mobile app is under review by the Apple App and Google Play stores, and is expected to be available in early May. The CWC app is designed for all Wisconsin residents, including those sheltering-in-place, under quarantine, working in essential jobs or soon returning to work as Wisconsin opens.
Healing from home: UW-Madison engineers support telehealth providers
Before mental health or addiction treatment providers launch telehealth services, researchers in the Center for Health Enhancement Systems Studies (CHESS) at the University of Wisconsin-Madison can offer training and preparation guided by detailed, proven healthcare systems engineering models. The COVID-19 pandemic has afforded little time for such gradual, deliberate planning. Outside of residential treatment centers, the vast majority of providers have quickly shifted to telehealth.
Nonetheless, as the home of U.S. Substance Abuse and Mental Health Services Administration-funded technology transfer centers for mental health, addiction and prevention services across the Great Lakes region, CHESS is helping providers navigate this abrupt transition. The center, based in the Department of Industrial and Systems Engineering at UW-Madison, is sharing best practices and resources, hosting webinars featuring clinicians with previous telehealth experience, and bringing together state leaders in the fields to share approaches and discuss policy changes.

Researchers aim to develop alternative COVID-19 testing method
The availability of COVID-19 tests in recent weeks has been limited, and demand is only expected to increase going forward. David Beebe, a professor of pathology and laboratory medicine and biomedical engineering at UW-Madison, is among the researchers working on developing a viable alternative. Beebe is an expert in microfluidics, with experience developing low-cost assays for infectious disease. He is collaborating with David O’Connor, a professor at the UW School of Medicine and Public Health, and Thomas Friedrich, a professor in the UW School of Veterinary Medicine, to develop an alternative COVID-19 testing method. The team aims to create a high-throughput, low-cost test that can be quickly and broadly implemented, using instruments that are available in nearly all clinical labs. Beebe estimates that about 100 samples could be tested in an hour using this method.

Going online on the fly: Faculty adjust to teaching, supporting from afar
When UW-Madison announced plans on March 11 to shift to alternate delivery of courses—initially temporarily, then through the end of the spring 2020 semester due to the global coronavirus pandemic—College of Engineering faculty had their own homework: converting all their in-person classes to an online format without substantially sacrificing the quality of education. And they had less than two weeks to do it. In the run-up to the return of classes on March 23, faculty and staff across the college worked feverishly to shift more than 1,000 courses, lab sections, independent studies and seminars to online formats.

UW–Madison engineer works with local health leaders to develop COVID-19 prediction models
A University of Wisconsin–Madison industrial engineer has led the development of models that are among the tools aiding health officials in Dane County and south-central Wisconsin as they prepare for and respond to COVID-19. Oguzhan Alagoz, a professor of industrial and systems engineering at UW-Madison and an expert in infectious disease modeling, has worked closely with colleagues in the School of Medicine and Public Health and at UW Health to develop and refine them. He has also shared his efforts with the Wisconsin Department of Health Services. The models use a swath of relevant, research-based parameters to predict the number of cases of COVID-19 in the region.

Educational engineering games take stay-at-home kids to the next level
The best-laid plans of many parents are falling apart after weeks of keeping their kids home during the COVID-19 pandemic—and for many families, Netflix binges and video games are replacing any attempts at home schooling. But University of Wisconsin-Madison engineers have developed a few more options for productive screen time. In recent years, they have collaborated with UW-Madison’s Field Day Lab to create educational—but most importantly, fun—games aimed at middle and high schoolers. Over the last four years, the Materials Research Science and Engineering Center (MRSEC) at UW-Madison, a National Science Foundation-funded center that supports materials science research and promotes education and public engagement, has created three games focused on materials science.

It could be possible to face a pandemic with reusable PPE
As COVID-19 cases surge across the United States, medical workers have scrambled to find ways to fill critical gaps in the nation’s personal protective equipment supply—in part because single-use PPE such as gowns and N95 masks are being discarded by the millions. Andrea Hicks, an assistant professor of civil and environmental engineering, is studying how reusable PPE might help fill critical shortages. The National Science Foundation is funding her research with a one-year, $78,394 Rapid Response Research (RAPID) grant.

How a UW-Madison engineer could help beat a virus at its own game
As the COVID-19 pandemic continues to spread across the United States and the world, many are putting their hope in science to bring an end to the virus, or at least make it manageable. But it’s not just virologists and epidemiologists who will find the way forward. Researchers from all sorts of disciplines are pivoting their research to help out with the pandemic. One is John Yin, Vilas Distinguished Achievement Professor in the Department of Chemical and Biological Engineering at UW-Madison, who uses experimental and computational methods to understand how viruses spread. Yin is working on several projects that could have a direct bearing on COVID-19, and says he’s ramping up work on them to help combat the virus.

Online platform helps healthcare facilities in need of face shields meet their match
Hospitals around the world are scrambling to secure enough personal protective equipment to safeguard their workers while treating the approaching wave of coronavirus patients. Manufacturers large and small are retooling their production lines to try to fill the gap. But that still leaves a huge logistical challenge: matching up the right suppliers with the right buyers. UW-Madison engineers have created an automated online platform to optimize and then facilitate those connections. The project is an outgrowth of the university-industry collaboration that created the Badger Shield, the open-source design for medical face shields that’s now being used by manufacturers around the country, including Ford. Organizations ranging from healthcare facilities to the U.S. Postal Service, fire departments, homeless shelters, nursing homes and more have requested millions of face shields using the online form. Justin Boutilier, an assistant professor of industrial and systems engineering at UW-Madison, has secured a National Science Foundation (NSF) grant to support his team’s work on the automated online platform. The one-year, $100,000 grant is through NSF’s Rapid Response Research (RAPID) program, which the agency is using to fund timely projects related to the global COVID-19 pandemic.
IE alum races from Utah to Wisconsin to contribute ventilator expertise to GE Healthcare
For Tyler Vermey, a crazy cross-country trip that included the aftermath of an earthquake and a raging blizzard was just the beginning of his role in fighting the COVID-19 pandemic. Until March 15, he and his wife had been keeping an eye on the pandemic from their home in Utah. “Like anyone else, we were just monitoring the outbreak and taking precautions,” Vermey says. “Then I got a call asking me to come back to Madison to help with making flow control valves for ventilators.”
Read more about Vermey’s journey from Utah to Madison and how he still draws on his engineering education today.
Engine emission researchers retool to identify effective N95 mask alternatives
As our world faces massive shortages of N95 masks, there is growing concern for the safety of healthcare workers who rely on these specialized masks and other personal protective equipment (PPE) to treat COVID-19 patients. Now, new research in an unusual area—internal combustion engines—at the University of Wisconsin-Madison is aiding in the development of alternative N95 masks in response to this urgent need. Dave Rothamer, a mechanical engineering professor and a leading expert in internal combustion engines, is leveraging the tools he uses to measure the particulate matter emitted from combustion engines for a new purpose: He has converted the instruments so that he can measure the filtration efficiency of different candidate materials for face masks.
