Before entering research he was Founder and Technical Director of 6 Internet Limited, a server hosting and application development specialist and holds a first-class BA (Hons) in Mathematics and a PhD in Mathematical Statistics from Trinity College Dublin.
Louis's current primary research interest is at the interface between cryptography and statistics, with the focus on privacy preserving statistical analyses. His personal interest is on the statistics side of this fusion, developing novel statistical methodology which is amenable to use in the constrained environment of encrypted computation made possible by recent developments in homomorphic encryption.
His other main strand of research is in reliability theory, where interest is in the structural reliability of engineered systems, usually taken from a Bayesian perspective. He also has research interests in computational acceleration of Hidden Markov Models (HMMs) as used in medical genomics which result in intractable inference when dependency is introduced between different genome sequences. Threaded through all these research interests is a particular interest in modern massively parallel computing architectures such as GPUs and the development of statistical methodology which is amenable to implementation in such environments.
