Dr Nicos Angelopoulos
Lecturer in Computational Systems Immunity
Trosolwg
I am a computer scientist working on computational and statistical aspects of
bio data analytics. I use knowledge representation methods and tools in machine
learning as well as in building practical, well engineered scientific code.
Currently a lecturer in Computational Systems Immunity at
Cardiff University's Systems Immunity Research Institute, working in close
collaboration with the sepsis group.
Previously I worked on (a) methodological projects in Markov chain Monte Carlo simulations
for Bayesian machine learning over priors defined with probabilistic logic programs
(Bims, University of York), (b) mass spectormetry functional data analytics (Imperial College)
and (c) genomic models of cancer evolution and cancer precision medicine (Sanger Institute).
I am staunch proponent of open source software, both in the systems I use in my
research (SWI-Prolog, Linux, R, Latex) and in publishing open source code with all my
papers (github page).
Bywgraffiad
Since my PhD I worked as a researcher on a number of projects in the UK and the Netherlands.
The last few years my research has focused on the development and application of principled
formalisms that combine logic and probability along with associated stochastic algorithms in computational biology.
Previously I worked in a number of research positions, including
- senior staff scientist in applied statistics at the Sanger Institute's Cancer Genome Project (now CASM)
- research fellow at University of York where I worked with James Cussens

I have conducted my research at prestigious UK and Dutch universities and institutes.
My area of expertise lies in the intersection of machine learning,
artificial intelligence and computational biology.
I am interested in theories that can model uncertainty and
have strong foundations in probability theory along with computational systems
that can reason with and learn such complex models from large data sets.
- during 2000-2010 I worked closely with James Cussens in York
in developing an elegant Probabilistic Logic Programming language
for Bayesian machine learning Bims. We published a number of papers
on theoretical aspects of the approach in high profile computer science conferences
such as UAI and IJCAI as well as on the application to specific datasets. - since 2011 I have been working in computational biology using AI techniques.
I have pursued open source and open data research throughout my career, having published open source
analysis methods and tools with the vast majority of my papers.
My work in computational biology includes theoretical work blending knowledge and inference with logical
and probabilistic foundations. My work also encompasses applied tools such as Real, which provides a
powerful bridge to the R statistical programming environment. - while at Sanger, I worked on high quality clinical and mutational datasets including survival analysis, precision oncology and cancer evolution based on mutational patterns in diverse cancers including hematological and solid tumour cancers. I was fortunate to work on a number papers, and substantially contributed to 3 substantial papers:
- GrinfeldJ+2018 (NEJM): precision oncology in myeloproliferative neoplasm
- MitchellTJ+2018 (Cell): statistical inference of landmark events in clear cell renal cell cancer
- MauraF+2019 (Nat Coms): Bayesian networks for cancer epistasis in multiple myeloma
