(Press-News.org) Protein-based drugs are reshaping how we treat cancer and chronic illness, including diabetes, rheumatoid arthritis and multiple sclerosis. But behind each medicine is a complex manufacturing process, one that can be slowed down or derailed by microscopic contaminants. Chemical engineer Nick Vecchiarello at the University of Virginia’s School of Engineering and Applied Science wants to change that, and the National Science Foundation has taken notice.
Vecchiarello, an assistant professor in the Department of Chemical Engineering, has earned an NSF CAREER Award to support his research into building new kinds of molecularly engineered surfaces. The $600,000 grant will fund efforts to design materials that can more effectively purify these drugs during production — filtering out everything from stray DNA and proteins to viruses that can slip in during the manufacturing process.
The prestigious five-year grant recognizes early-career faculty who demonstrate the potential to serve as academic role models as they lead research advances in their field.
Our job is to separate what’s valuable from what’s potentially dangerous.
“These medicines are made inside living cells, which don’t just make the drug, they also make a lot of other material you don’t want in the final product,” Vecchiarello said. “Our job is to separate what’s valuable from what’s potentially dangerous.”
To do that, Vecchiarello and his team are developing customized surfaces coated with short chains of amino acids called peptides. These peptides can be tuned to bind or reject specific molecules, depending on what the manufacturing process requires. The coated surfaces are used in chromatography columns — tools that act like microscopic sieves, separating out molecules based on size, shape or chemistry.
What makes this work especially powerful is how the surfaces are developed: Vecchiarello uses high-throughput screening to test many peptides at once, alongside computer modeling to understand why certain combinations work. That data can then guide the design of even better surfaces in a kind of feedback loop.
The expected result? A faster, cleaner, more cost-effective way to purify protein-based drugs that could save manufacturers millions of dollars by reducing waste and failed batches, while helping patients access vital treatments more affordably.
“This isn’t just about improving a single product,” he said. “It’s about transforming the materials and processes that underlie a major part of the pharmaceutical industry.”
The award will also support student training and outreach, including a summer workshop series to help the next generation of engineers gain hands-on experience in bioseparations and materials design.
Vecchiarello’s work complements the computational research of colleague Camille Bilodeau, who also received a CAREER Award earlier this year. Together, the two labs are helping to create an innovative, multidisciplinary approach to drug purification and advanced materials research.
Before joining UVA in 2023, Vecchiarello earned his Ph.D. from Rensselaer Polytechnic Institute and worked as a purification scientist at Amgen, followed by a postdoctoral role at MIT. His lab recently published its first paper, led by Ph.D. student Janani Ram.
“Receiving the CAREER Award is a tremendous honor,” Vecchiarello said. “It allows us to pursue bold research, explore new ideas and ultimately create materials that could have a lasting impact on health care.”

Tiny parasitoid flies show how early-life competition shapes adult success
2025-07-10
In a new study published and featured in the Annals of the Entomological Society of America, researchers have discovered that the developmental struggles of young parasitoid flies can have lasting effects that echo into adulthood. Led by a team from St. Olaf College in collaboration with others from the University of Strathclyde and the University of Toronto, the study shows that when larvae of the acoustic parasitoid fly Ormia ochracea compete for resources inside a single cricket host, the consequences include reduced survival, smaller pupae, and ultimately smaller adult flies.

New coating for glass promises energy-saving windows
2025-07-10
HOUSTON – (July 10, 2025) – A new coating for glass developed by Rice University researchers and collaborators could help reduce energy bills, especially during the cold season, by preventing heat-loss from leaky windows. The material ⎯ a transparent film made by weaving carbon into the atomic lattice of boron nitride ⎯ forms a thin, tough layer that reflects heat, resists scratches and shrugs off moisture, UV light and temperature swings.
The researchers simulated how the material would behave in an actual-sized building in cities with cold winters like New York, Beijing and Calgary, showing it improved energy savings by 2.9% compared ...
Green spaces boost children’s cognitive skills and strengthen family well-being
2025-07-10
URBANA, Ill. – Access to nature promotes physical and mental health, and it is vital for children’s social and emotional development. Outdoor activities also influence family dynamics, helping to reduce stress and encourage connections. A new study from the University of Illinois Urbana-Champaign examines how green spaces and outdoor structures near the family residence interact with other factors in the household environment to influence executive functioning in early childhood.
“We looked at what people have outside their ...
Ancient trees dying faster than expected in Eastern Oregon
2025-07-10
Eastern Oregon’s Malheur National Forest boasts some of the state’s oldest trees, including pine and larch that live more than 500 years. But many of those ancient trees are dying at an alarming rate, a new analysis shows.
Between 2012 and 2023, a quarter of trees more than 300 years old in randomly located sites in roadless areas died, the study found. A triple whammy of drought, bug infestations and competition with younger trees is likely driving the decline.
“It’s sad to see so many old trees dying,” said lead researcher ...

Replacing mutated microglia with healthy microglia halts progression of genetic neurological disease in mice and humans
2025-07-10
Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) is a progressive neurological disease with an average age of onset of 43 years and an average life expectancy of only 3 to 5 years after symptoms begin. ALSP is caused by microglial mutation, the immune cells of the central nervous system (CNS). Currently, ALSP has no cure and treatments are limited.
All microglia rely on a kinase called colony-stimulating factor 1 receptor (CSF1R), which is only found in microglia and other myeloid cells. When CSF1R gene carries pathogenic ...

-With images-
In the tropical rainforests of Fiji, a genus of unusual plants has developed a remarkably simple but highly effective way to prevent violence between rival ant colonies: architecture.
In a new study published in Science, an international team led by Professor Guillaume Chomicki at Durham University has revealed how some species of the epiphytic plant Squamellaria (part of the coffee family, Rubiaceae) form peaceful and productive partnerships with multiple aggressive ant species simply by physically ...
Condo-style living helps keep the peace inside these ant plants
2025-07-10
Odd plants from a remote Pacific island reveal new insights into an important ecological question: how unrelated and antagonistic partners can form long-term mutualistic relationships with the same host.
Scientists studying ant plants in Fiji have discovered one way that a host plant can keep the peace among residents that might otherwise kill each other. By providing separate chambers inside a gradually enlarging tuber -- each chamber with an entry hole from the outside but no connection to any adjacent chamber -- the Squamellaria plant prevents conflicts between the multiple ant species that ...
