Marie Galligan - PhD Student

Current Area of Interest


My bachelor’s degree is in Mathematical Sciences and Computing, with an emphasis on statistics in the final two years.

My area of interest is biostatistics, the subject for which i’m hoping to obtain a PhD. I’m currently working with Prof. Thomas Brendan Murphy to develop novel techniques for the analysis of Glycomics data, generated by Pauline Rudd’s research group, to aid in the diagnosis and prognosis of different diseases and also to identify glcan biomarkers for these diseases.

An appropriate statistical model for this data needs to take into account that the data are relative, as opposed to absolute, quantities. Such data is referred to as compositional. There have been various methods developed to overcome the difficulties in the analysis of compositional data, but the research in this area is not extensive. I’m currently attempting to fit nested Dirichlet models to the data, which might then be used for classification purposes.

My PhD funding comes from IRCSET, under the program for Structured PhDs in Bioinformatics and Computational Biomedicine.
