Lee J. O'Riordan joined ICHEC in January, 2019 as a Computational Scientist, and is currently exploring the use of near-term quantum computing technologies for problems in the computational domain.

Lee completed the BSc (Hons) in Physics with Computing degree programme at Waterford Institute of Technology in 2010. During this time he interned at Analog Devices, Limerick, working on semiconductor device failure analysis. After the completion of his degree, he worked as a Software Developer with IBM Dublin, developing solutions for Websphere Portal. In 2011, Lee joined the Ultracold Quantum Gases group in University College Cork, and in 2012 the Quantum Systems Unit at the Okinawa Institute of Science and Technology Graduate University, Japan. Here, Lee completed his PhD, researching the control and manipulation of quantum states via analytical and numerical methods. He is an author of the 
GPUE simulation suite for Bose-Einstein condensate dynamics (C/C++, CUDA, Python, MATLAB, Mathematica).

Following this, in 2017 Lee joined the Molecular Biophysics and Integrated Bioimaging Division at Lawrence Berkeley Lab as a postdoctoral researcher. Here he investigated the use of many-core computing technologies for the X-ray free-electron laser (XFEL) crystallographic analysis of bio-molecular systems. During this time Lee contributed to the DIALS ,CCTBX, and ExaFEL projects (Python/C++/MPI), targeting scalability on the NERSC Cori supercomputer.
