Matthieu studied Applied Maths/Stats at the ENS Lyon (France) before doing his PhD in Grenoble (2007, INRIA Rhone-Alpes, France). He then joined BioSS in Dundee and Aberdeen (Scotland) from 2006 to 2009 as a Statistician. He then became a Research Fellow in the Maths and Comput. Sc. dpt of the INRA in Toulouse (France) in 2009 (present: detached position).
Matthieu is now a Senior Lecturer in Statistical Genetics at Massey University (New Zealand).
Matthieu's work focuses on deciphering relationships between entities in a complex (e.g. biological) system; please have a look at his research interests.
My research is motivated by the understanding of the structure(s) which govern(s) the behaviour of complex systems. Mostly, I have been working with high-throughput data generated by biological organims, regarded layers of components of different natures which interact with each other possibly fulfilling different goals.
To this end, I am interested in probabilistic graphical modelling as a convenient way of representing the system under study and how its constituting elements interact. I am often faced with high-dimensional data posing both statistical and computational challenges. Missingness in the data sets at hand can also be a hindrance. Data sets are heterogeneous (e.g. mixing discrete and continuous data), sampling is certainly not independent and identically distributed and off-equilibrium and measurements noisy.
Recently, I am moving towards a causal interpretation of learnt relationships, hopefully revealing realistic mechanisms which explain the inner functioning of the system.
