Tiny particles, big discoveries

“Millions of people in the world breathe dangerously polluted air. What excites me most about my research is that I’m doing something that makes a real impact on society.”

Will Vizuete is an associate professor in the Department of Environmental Sciences and Engineering at the UNC Gillings School of Global Public Health. 

Much of his research focuses on aerosol emissions, tiny particles floating in the atmosphere that, yes, can come out of a can of hairspray. But they can also come from nature — from plankton in the ocean, palm trees in the Amazon or pine trees in North Carolina. These natural aerosols, and man-made aerosols such as diesel engine exhaust, can have hazardous effects on the climate and public health all around the world.

Vizuete captures aerosols from around the world and brings them back for testing in his lab at the Gillings School. He uses high-performance computers and 3D simulations that model the atmosphere to re-create atmospheric exposures to better predict the chemical responses of aerosols.

The archive of one of the country’s most important and prolific photographers of Black life in the twentieth century has a new home at UNC-Chapel Hill’s University Libraries.

The Roland L. Freeman Collection is now part of the Southern Folklife Collection at the Wilson Special Collections Library. The collection is a gift from the Kohler Foundation, a family foundation that supports the arts and education.

Carolina now gains access to a massive compilation of work by Freeman from a career that spans more than fifty years of documenting Black communities, public figures and folk art and artisans. It consists of nearly 24,000 slides, 10,000 photographic prints, 400,000 negatives and 9,000 contact sheets. Also included are publications and an archive of Freeman’s papers.

Freeman devoted much of his career to documenting Black communities across the South, with a particular emphasis on art, cultural events and folk culture in all its manifestations. He co-directed the Mississippi Folklife Project for the Smithsonian Institution’s Center for Folklife and Cultural Heritage in 1970 and was later a research associate there.

“Roland provides a portrait of Black style and Black aesthetics that is unparalleled in the history of American photography. He understood the possibility of capturing deep narratives of tradition, especially in the Black South and the journey of those traditions in the Great Migration, that no one else has done” said Glenn Hinson, associate professor in UNC-Chapel Hill’s department of anthropology and a longtime collaborator with Freeman.

“The Southern Folklife Collection is deeply honored and excited to preserve and provide access to Roland Freeman’s photographic archive,” said Steve Weiss, curator of the Southern Folklife Collection. “Freeman’s research and documentation of African American Folklife is innovative in its collaborative methodology and a landmark in the study of African American quilters. His collection will be an invaluable resource for students, historians, folklorists, documentary filmmakers and many more groups.”

    string(2664) "Portrait of Brad HendricksBrad Hendricks – assistant professor of accounting at UNC Kenan-Flagler Business School – is an expert on corporate disclosure, initial public offerings (IPOs) as well as entrepreneurship. So it’s only fitting he’s teaching a new course, Profits, People, Planets and Purpose, designed to inspire undergraduates to pursue business education and opportunities.

The course also presents undergrads with a unique experiential learning opportunity to apply theory to practice. Students manage “companies” while competing against their classmates in a simulation.

Hendricks likes to see their competitive natures show: “This generation is so adept at self-learning, experiential learning, that putting them in a gaming scenario that mimics the workplace is a fun, intuitive and risk-free way for them to learn how to make smart business decisions.”

Profits, People, Planets and Purpose is just one example of Hendricks’ impactful teaching at UNC Kenan-Flagler.

“Brad is a top-tier researcher and an amazing teacher,” said Jana Raedy, associate professor and EY Scholar in accounting and senior associate dean of business and operations. “He has not only made a major impact on the academic community with his research, but also has had a significant impact on the business community more broadly. He teaches extremely difficult material in a way that, while challenging the students to think critically, is accessible to them.”

He won the Business School’s 2021-22 Bullard Faculty Research Impact Award, which recognizes a professor each year whose research has had a significant effect on the practice of business. He is the first assistant professor to win it. Additionally, Hendricks received the Glenn McLaughlin Prize for Research in Accounting and Ethics and the Morgan Stanley Prize for Best Paper in 2021.

UNC Kenan-Flagler students also recognized his work in the classroom: He won the prestigious Weatherspoon Teaching Excellence Award in the Master of Accounting (MAC) Program in 2016 and again in 2022.

“Teaching really matters here at UNC Kenan-Flagler. There’s a high value placed on it, and I do the best I can. I am glad that students find such value in my class, despite its reputation for also being the most difficult class in the MAC Program,” said Hendricks.

    string(2448) "Portrait of Vincent BrownVincent Brown is on a mission to open minds to a much broader view of American history, one that incorporates Black history and Black perspectives into the canon.

“We need to have a much broader sense of what American history is, who counts within American history and how it develops over time,” said Brown, the Charles Warren Professor of American History and professor of African and African American studies at Harvard University. He teaches courses on the history of slavery in the Americas.

Although Brown grew up in Southern California, his visit to Carolina “is going to be a bit of a homecoming for me,” he said, pointing out that he did research in Wilson Library and completed his dissertation at neighboring Duke University.

Brown returned to North Carolina to give the first Dr. Genna Rae McNeil Endowed Black History Month Lecture, named for the first Black tenure-track faculty member in the history department. McNeil retired in 2021 after 36 years at Carolina, where she helped establish what was then known as the African American History Month Lecture.

The University’s establishment of an endowed lecture series on Black history and Brown’s talk come at a critical time.

“It has always been a struggle to establish the very idea that Black history is something worthy of study. It is something that people have had to fight for, from when Carter G. Woodson established Negro History Week way back in 1926. Even today, it’s something that is contentious,” Brown said.

Brown believes both Black history and Black perspectives are worthy of study, for understanding racism and much more. “Certainly the history of race and racism is fundamental to the way we have to understand the Black experience in the Americas and in the United States. But then the Black experience and Black struggles exceed the history of racism as well. And I think if we collapse the two too neatly, we can miss all of those things that Black people have done, all the consequences of their history that are not easily reducible to the study of racism.”
