, assistant professor of physics in the (A&S), has been awarded a five-year (CAREER) grant from the National Science Foundation.

The project, titled “Ultrathin sheets on curved liquid surfaces: Stress focusing and interfacial assembly,” looks to investigate so-called “geometric frustration” in a class of extremely bendable materials. The effects of mismatched geometries are familiar: flat bandages don’t stick so well to curved knuckles or elbows, and automotive metal must be laboriously stamped or forged to make a fender. Paulsen’s team aims to get something useful out of all this frustration. They will study how ultrathin polymer films (a thousand times thinner than a human hair) can be guided along curved liquid surfaces in predictable ways. The hope is that these studies will uncover new ways for controlling liquids, whether it is containing toxic or corrosive substances or a new way of delivering medicine to where it is most needed in the body.
In addition to funding the research, the grant allows for several outreach components beyond the ϲ campus. The grant will support two . Lab members will be trained to work with local high school students interested in learning more about soft matter research. High school teachers will also be invited to conduct research internships, and a laboratory YouTube channel will be created with the potential of reaching a worldwide audience.
Young scientists from all over Upstate New York will also be able to get hands-on experience with the physical science with an installation on wrinkling currently being developed for the (The MOST) in downtown ϲ.

“Having the resources to share and expand this research into the greater community and beyond is really wonderful,” says Paulsen. “The field of soft matter physics is strong at ϲ, and this award will allow us to perhaps reach the next generation of physicists.”
Paulsen joined the ϲ physics department in 2015 after spending two years at the University of Massachusetts Amherst as a postdoctoral research associate. He received his Ph.D. in physics from the University of Chicago, and is a member of the American Association of Physics Teachers and the American Physical Society.
The Faculty Early Career Development Program is one of the National Science Foundation’s most prestigious awards in support of the early career-development activities of teacher-scholars who most effectively integrate research and education within the context of the mission of their organization.
