The organization is honoring Grzywacz for his contribution to the field including his work to help discover a new element on the periodic table. Grzywacz, director of the UT-ORNL Joint Institute for Nuclear Physics and Applications, helped develop a process that measures the decay of nuclear materials down to one millionth of a second, which was vital in proving the existence of new element 117.
Grzywacz is now among 11 current physics and astronomy faculty members who are fellows of the society. The others are Cristian Batista, Elbio Dagotto, Mike Fitzsimmons, Geoff Greene, Tony Mezzacappa, Adriana Moreo, Thomas Papenbrock, Lee Riedinger, Soren Sorensen, and Hanno Weitering.
