I am an assistant professor at the Departments of Physics and Astronomy & Astrophysics of The Pennsylvania State University.
My research focuses on the study of extreme astrophysical events, such as compact binary mergers and core-collapse supernovae. To this aim I design, implement, and analyze large-scale high-performance computing general-relativistic simulations. My goal is to use simulations, in combination with gravitational-waves and electromagnetic observations, to address fundamental questions such as: what is the nature matter at extreme densities? What is the origin of heavy elements? What is the fate of massive stars? I am also interested in the development of new computational techniques and in the study of the fundamental physical processes operating in these events.

Penn State Astrophysicist David Radice named Knerr Early Career Professor
2024-11-18
David Radice, associate professor of physics and of astronomy and astrophysics, has been named Henry W. Knerr Early Career Professor of Physics. Geroge R. and Lisabeth Knerr Poore established the professorship in 2021 in honor of Henry Knerr to support early-career faculty in the Eberly College of Science. The professorship offers recognition for outstanding early accomplishments and provides financial support to encourage promising young faculty members to establish a commitment to teaching and explore new areas of research.

Three Penn State researchers awarded scientific grants from Kaufman Foundation
2024-11-13
The Charles E. Kaufman Foundation—a supporting organization of The Pittsburgh Foundation, which works to improve the quality of life in the Pittsburgh region—has selected three Penn State researchers to receive scientific research grants. The foundation awards grants to scientists at institutes of higher learning in Pennsylvania who are conducting innovative, fundamental scientific research in the fields of biology, chemistry and physics.

What happens when neutron stars collide?
2024-06-18
When stars collapse, they can leave behind incredibly dense but relatively small and cold remnants called neutron stars. If two stars collapse in close proximity, the leftover binary neutron stars spiral in and eventually collide, and the interface where the two stars begin merging becomes incredibly hot. New simulations of these events show hot neutrinos — tiny, essentially massless particles that rarely interact with other matter — that are created during the collision can be briefly trapped at these interfaces and remain out of equilibrium with the cold cores of the merging stars for 2 to 3 milliseconds. During this time, the simulations show that the neutrinos can weakly interact with the matter of the stars, helping to drive the particles back toward equilibrium — and lending new insight into the physics of these powerful events.

David Radice and Stephanie Wissel receive 2022 Climate and Diversity Awards
2023-02-09
The Eberly College of Science Climate and Diversity Committee has selected three individuals and one group to receive 2022 Climate and Diversity Awards in recognition of their extraordinary commitment to enhancing the environment of mutual respect and diversity in the college over the past year. The award is supported by the Santacroce Family Climate and Diversity Fund in the Eberly College of Science. The awardees and nominees were honored at an annual ceremony on Thursday, January 16, 2023, to recognize their efforts to make our college community supportive and welcoming to everyone.
The CalBridge program— initiated at Cal Poly Pomona—aims to increase the diversity of physics practitioners by identifying and assisting members of groups historically underrepresented in physics, including by connecting students with Ph.D. programs. With guidance from the Physics Department’s CalBridge program leadership committee, Penn State is one of a handful of universities outside of California to welcome CalBridge participants to its graduate program. The leadership committee includes Stephanie Wissel, Downsbrough Early Career Assistant Professor of Physics and of Astronomy and Astrophysics; Nathan Keim, associate research professor of physics; and David Radice, assistant professor of physics and of astronomy and astrophysics. The committee prepares recruiting materials for the program, tracks applicants through the admissions process, and provides feedback about all applicants at the end of the process. It also helps to support these students’ progress once they are at Penn State.
“This feedback is important to the program and future students in making sure that they understand what we are looking for in applicants, but it has also generated important discussions with the admissions committee about how to equitably evaluate applications,” said a nominator. “After just two years with the program, it has already become a major part of our efforts to diversify the Physics Department’s graduate program.”
