Hendrik Schatz University Distinguished Professor of Physics, JINA-CEE Department Head Keywords: Nuclear Astrophysics, Recoil Separator, Gas Target Neutron Detectors, Neutron Stars, r-process Experimental Nuclear Astrophysics About • MS, Physics, University of Karlsruhe, 1993 • PhD, Physics, University of Heidelberg, 1997 • Joined the laboratory in December 1999 • schatz@frib.msu.edu Research The goal of our experimental and theoretical research program is to understand the nuclear processes that shape the cosmos by creating elements and generating energy. The focus is on the most extreme environments thought to exist in nature: thermonuclear explosions on neutron stars; neutron star collisions; core collapse supernovae; and the strange insides of neutron stars, where rare isotopes are stable and cold fusion is actually happening. Most student projects in our group cut across experiment and theory, and across nuclear physics and astrophysics. Experiments restage at FRIB the same reactions that happen in astrophysical environments and include opportunities to use, design, and build new equipment. Theory focuses on a broad range of astrophysical computer models that can be used to identify interesting nuclear processes, explore the impact of new measurements, and compare with observations. Ultimately we seek to answer the question of how the incredible variety of elements our world is made of came about. Biography I grew up in Lörrach in Germany, located right where Germany, Switzerland, and France meet. I got interested in nuclear astrophysics when studying in Karlsruhe, Germany and went to Notre Dame to do my PhD in that field. In addition to Notre Dame I performed experiments at Argonne, IUCF, and TRIUMF. I did a short three-month postdoc at UC Berkeley in the astronomy department, before working on storage rings at GSI in Germany, and then coming to MSU in 1999 to build an experimental nuclear astrophysics program. I co-founded with colleagues at Notre Dame and Chicago the Joint Institute for Nuclear Astrophysics, now JINA-CEE and IReNA. The goal of these was to create a research environment where discipline boundaries disappear, and we combine interdisciplinary expertise across institutions. When FRIB offered the opportunity for low-energy beams I got interested in building the SECAR recoil separator, which is just now being completed and will enable direct measurements of astrophysical reactions. How Students can Contribute as Part of my Research Team Our group uses a very broad range of detectors, separators, and spectrometers to answer a variety of open questions. It is embedded in the JINA-CEE and IReNA collaborative networks providing national and international networking opportunities, including opportunities for research stays and exchanges (for example to work on a particular interpretation of experimental results), visits, and many leadership and professional development opportunities. The goal in our group is to create an environment where all students can be successful and can follow their interests across fields as well as across experiment and theory, while getting prepared for a broad range of careers in industry, national laboratories, academia, or nuclear astrophysics. We fully support and follow the FRIB and Physics Department code of conduct, as well as the newly developed JINA-CEE code of conduct.

Gregory Severin Assistant Professor of Chemistry Keywords: Isotope Production, Radiochemistry, Applied Nuclear Physics Radiochemistry About • MS, Chemistry, University of Wisconsin-Madison, 2006 • PhD, Nuclear Physics, University of Wisconsin- Madison, 2010 • Joined the laboratory in August 2016 • severin@frib.msu.edu Research Our group is developing a method for collecting and purifying byproduct radionuclides from FRIB called “isotope harvesting.” Harvested isotopes will be used as research tools in other areas like nuclear medicine, biosystems radiotracing, and nuclear data for security applications.

Phys Med Biol 2017;63:015026. doi:10.1088/1361-6560/aa9b44. Biography I grew up in Okemos, Michigan, and have been fascinated with nuclear science since visiting the National Superconducting Cyclotron Laboratory at MSU as a teenager. I worked on high-precision beta spectroscopy as a graduate student, and then went on to isotope production for medical applications as a postdoc. I was fortunate to spend several years at the Technical University of Denmark as a scientist in applied nuclear physics and radiochemistry before returning to the Lansing area for a faculty appointment in 2016. How students can contribute as part of my research team Students in my group have an opportunity to bridge the cutting-edge nuclear physics technology at FRIB to other fields. This allows broad definition of a PhD project and lets the students decide how deep into any subject they want to dive. The expectation for students in my group is that they will acquire a working knowledge of nuclear physics and at least one other topic, like medical imaging, detector physics, inorganic chemistry, or analytical chemistry. All viewpoints are welcome, and creativity is encouraged. Illustration of isotope harvesting and medical applications. 73 2022_FRIB_Graduate_Brochurev4.indd 73 10/29/2021 3:33:57 PM
