Thomas Spriggs
About
As a postdoc in the Quantum Matter and Artificial Intelligence (QMAI) group at TU Delft I am interested in high energy physics, quantum information, and machine learning. Currently I am working on encorporating bespoke machine learning models for understanding the dynamics of quantum many-body systems.I am based at both QuTech and the Kavli Institute of Nanoscience, having been awarded my PhD in theoretical physics from Swansea University (after a visiting position at Trinity College Dublin) and my MPhys in theoretical physics from Durham University. My PhD was funded by the Artifcial Intelligence, Machine Learning, and Advanced Computing (AIMLAC) award for interdisciplinary research; during this period I was also a machine learning engineer at Amplyfi (a UK-based AI-powered market intelligence compary).
Outside of this, I am, unfortunately, a fan of Everton F.C., a keen runner and powerlifter, and a bad website-maker (and bad-website maker, I guess).
If you are interested in any element of my work, please reach out at t.e.spriggs@tudelft.nl.
