John Brennan joined ICHEC in March, 2020 as a Computational Scientist. He is working on the PRACE WP8 QuantEx project which looks at developing scalable quantum circuit simulation tools for exa-scale platforms. 

In 2013, John completed a BSc (Double Hons) in pure mathematics and mathematical physics at Maynooth University. After that, he pursued a PhD in Theoretical physics at Maynooth University which he completed in 2018. His research involved the use and development of numerical methods to study topological quantum phases and their applications in topological quantum computation. John then worked as a lecturer at Maynooth University until January 2020. He lectured undergraduate courses in vector calculus, complex analysis, fluid mechanics and computational physics.
