Tan Ahn

Tan Ahn is an Associate Professor in the Department of Physics & Astronomy at the University of Notre Dame. His research focuses on experimental nuclear physics, particularly cluster structure in nuclei, testing ab-initio theories, and developing active-target techniques using radioactive ion beams. He leads experiments at facilities like the Institute for Structure and Nuclear Astrophysics (ISNA) at Notre Dame, ATLAS at Argonne, and NSCL at Michigan State University. His work addresses astrophysical phenomena such as X-ray bursts and nucleosynthesis processes.

Education: B.S., M.S., and Ph.D. in Physics from Stony Brook University (2002–2008). Postdoctoral and research roles included Yale University (2008–2011), Michigan State University (2011–2014), and institutions in Germany (2006–2008). Teaching includes adjunct roles at the University of New Haven and teaching assistantships at Stony Brook.

Research interests include fusion reactions with halo nuclei, gamma-ray spectroscopy, and detector development. His lab develops active-target time-projection chambers (AT-TPC) to study unstable nuclei. Collaborations involve international teams and cutting-edge facilities.

Current projects explore cluster structures in light nuclei, alpha-induced reactions for astrophysics, and fusion studies with radioactive beams. Students and postdocs in his group work on detector design, data analysis, and experimental techniques.
