Dr Lee J. O'Riordan is Quantum Activity Lead at ICHEC and works at the intersection of quantum technologies and HPC. His research involves using hybrid classical-quantum methods to solve problems for academic and industry partners, such as the QNLP project with Intel, the QPFAS project, and the recently funded NEASQC project. 

Prior to joining ICHEC in 2018, he was postdoctoral researcher at the Molecular Biophysics and Integrated Bioimaging Division at Lawrence Berkeley Lab where 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 he contributed to the DIALS ,CCTBX, and ExaFEL projects (Python/C++/MPI), targeting scalability on the NERSC Cori supercomputer.

Dr O'Riordan's previous experience includes the Quantum Systems Unit at the Okinawa Institute of Science and Technology Graduate University, Japan where he 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). Additional experience includes, Software Developer, IBM Dublin, developing solutions for Websphere Portal (2012) and at Ultracold Quantum Gases group in University College Cork (2011). While undertaking his undergraduate studies (BSc (Hons) in Physics with Computing at Waterford Institute of Technology) he interned at Analog Devices, Limerick, where he worked on semiconductor device failure analysis.

Qualifications include B.Sc. (Hons) in Physics with Computing, Waterford Institute of Technology, Ireland, PhD in Physics, Quantum Systems, Okinawa Institute of Science and Technology Graduate University, Japan.
