Background

Dr. Justin Gage Lietz is a performance engineer in the Algorithms and Performance Analysis Group at the National Center for Computational Sciences at Oak Ridge National Laboratory. He is a co-developer of the Nuclear Tensor Contraction Library (NTCL) which leverages supercomputing resources like Summit and Frontier to compute properties of interacting quantum systems.

His research focuses on improving the performance of quantum many-body physics calculations. This involves developing massively parallel algorithms and data structures for GPU based computing platforms, and investigating ways in which machine learning and quantum computing can accelerate simulations.

Dr. Lietz earned his Ph.D. in Physics with a dual degree in Computational Math, Science and Engineering at Michigan State University. While at MSU he was located at the National Superconducting Cyclotron Laboratory where he studied theoretical nuclear physics and computational quantum mechanics.
