Andrew Ratkiewicz earned a BS in physics from Indiana University South Bend and a PhD in physics from Michigan State University. He completed his post-graduate study at the National Superconducting Cyclotron Laboratory at Michigan State University, where he measured the evolution of collectivity in exotic isotopes of silicon and the collapse of the N=28 magic number. After graduating with his PhD, he moved to Oak Ridge National Lab, where he worked as a postdoc for Rutgers University to combine the Oak Ridge Rutgers University Barrel Array (ORRUBA) and GAMMASPHERE as a large-scale particle-gamma spectrometer.

Since joining LLNL as a postdoctoral research staff member in 2015, Ratkiewicz has been working to probe the strength of nuclear-plasma interactions using the National Ignition Facility (NIF) and to benchmark the performance of the (d,p) reaction as a surrogate for neutron capture. He has also worked on neutron imaging and neutron transport.
