Research Associate

Research Associate in Experimental Nuclear Science – Lifetime measurement and spectroscopy, fixed term

Position Summary

The National Superconducting Cyclotron Laboratory (NSCL) invites applications from outstanding candidates for a fixed-term research associate (Postdoctoral Researcher) position in the area of experimental nuclear science, who will work in the research group of Prof. Hiro Iwasaki.

The successful candidate will work primarily on the lifetime measurement and spectroscopy program with fast and reaccelerated rare-isotope beams available at NSCL. The focus of the group is the experimental investigation of nuclear shell and shape evolution far from stability and electromagnetic responses of weakly-bound nuclei.  Experiments will be performed utilizing large gamma-ray arrays such as GRETINA and SeGA in combination with ancillary detectors and spectrograph. Experience in experimental nuclear research including analysis of nuclear structure or reaction data and related simulation works is desirable.

NSCL is one of the world’s flagship nuclear science research facilities. The Laboratory’s research program is broad: fast, stopped, and reaccelerated beams of rare-isotopes are available to address key scientific questions concerning the creation of the elements in the cosmos, the limits of nuclear stability, the properties of nuclei with extreme neutron-to-proton ratios, and the equation of state of neutron-rich nuclear matter as it may exist inside neutron stars. Postdoctoral researchers play an important role in expanding, improving and utilizing the world-class experimental capabilities at the Laboratory. Experimentalists often work closely with theorists in the Laboratory and beyond and projects can involve high-performance computing.

NSCL is part of the Facility for Rare Isotope Beam (FRIB) Laboratory, which aspires to become the world’s leading laboratory for education and research in rare isotope science, in accelerator science, and in applications of rare isotopes to meet societal needs. To realize this vison, the FRIB Laboratory builds on the expertise and the achievements of NSCL as it establishes FRIB, which will extend the frontier of nuclear science through unprecedented discovery potential.

Research Associate positions are typically for two years, depending on the availability of funds. Renewal for the second year is based on a performance evaluation. A third year is possible, subject to funding and satisfactory performance evaluations.

Besides the excellent research environment, the FRIB Laboratory offers a strong program for mentoring postdoctoral researchers in preparation for the next steps in their careers. You can read more in the postdoc mentoring plan. Postdoctoral researchers play a role in running the Laboratory, from leading forefront research to serving on important committees. They help supervise students and, for those interested, there are opportunities to engage with teaching and outreach.

NSCL is funded by the National Science Foundation through the Nuclear Physics program of the NSF Physics Division to be a national user facility with a mission to provide beams of rare isotopes for researchers from around the world. Hundreds of users come to Michigan State University each year to take advantage of our facilities and explore the inner workings of atoms and their role in the universe.

The FRIB Laboratory is a major administrative unit within Michigan State University, comprised of NSCL and the FRIB Project. MSU is establishing FRIB as a scientific user facility with financial assistance from the Office of Nuclear Physics in the U.S. Department of Energy Office of Science (DOE-SC).

MSU is one of the largest university campuses in the United States with a beautiful campus of 5,000 tree-filled acres. It has 17 degree-granting colleges and is a center for academic and research activities as well as the arts and athletics.

The campus sits between Lansing (Michigan’s capital city) and East Lansing. The Lansing area has a population of 460,000 and offers lovely suburban areas, loft condos and other urban living opportunities as well as easy-to-get-to rural areas. A symphony orchestra, excellent health care, many community and professional theatres, rivers, lakes, outdoor festivals, close access to large cities and Lake Michigan make for a near-perfect living environment.

MSU is an affirmative action, equal opportunity employer and is committed to achieving excellence through cultural diversity. The University actively encourages applications and/or nominations of women, persons of color, veterans and persons with disabilities. Job applicants are considered for employment opportunities and employees are treated without regard to their race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or veteran status. The University actively encourages applications of women, persons of color, veterans, and persons with disabilities.
