Biography

I am a Chartered Statistician and Associate Professor with over 10 years experience. I enjoy working with big, messy data sets which have hidden relationships that only statistical methods can uncover. My main expertise is in:

  • Feature/variable selection
  • Multivariate analysis
  • Stochastic processes and time series analysis
  • Bayesian inference
  • Spatial and spatio-temporal modelling
  • Computational statistics

I have applied such methods in a diverse range of fields including:
  • Climate change (estimating past changes in climate from pollen, estimating changes in extreme for Ireland's future, estimating worldwide rates of sea level change)
  • Bioinformatics (biomarker discovering and validation for prostate cancer, visualising gene ontology signatures, predicting elite animal performance from single nucleotide polymorphisms)
  • Archaeology (radiocarbon dating, age-depth model building, astrochronology for the Devonian)
  • Quantitative ecology (stable isotope mixing models to estimate animal diets, monitoring fisheries discard rates in the Irish Sea)
  • Text mining (Maximum entropy models for hierarchical data classification)
  • Manufacturing analytics (Tool wear prediction for computerised numerical control machines, real time anomaly detection for multivariate time series)

Research

Research Interests

Text mining
As PI of the Enterprise Ireland Innovation Partnership Automatic Dynamic Product Classification I work on Bayesian methods for classification of textual data. We are currently applying these approaches to very large data sets provided by Clavis Insight Ltd concerning product classifications for online shopping websites

Extremes
As PI of the Environmental Protection Agency funded project Extreme Events in Calibrated Climate Models: Impacts for Ireland I work on adapting extreme value distributions to spatio-temporal, multivariate scenarios. I was also the chair of the 2010 European Science Foundation high-level conference on Extreme Environmental Events

Palaeoclimate modelling
My main field of research for the last 10 years has been the statistical reconstruction of palaeoclimate from proxy data. This has produced numerous PhD projects, concerning Multivariate misaligned time series for ice core and pollen records, Estimating worldwide rates of relative sea level change, and Identifying frequency behaviour of palaeoclimate records using Bayesian variable selection methods. This research involves a substantial computing element, and combines ideas in stochastic processes, state-space modelling, and long-tailed probability distributions. I have recently been appointed the leader of the ¿Data¿ working group of the Past Earth Network

Quantitative ecology
My interest in statistical ecology concerns Bayesian compositional modelling of data from stable isotope experiments on ecosystems. Through this research we have developed the widely-used R computer package SIAR (>700 citations since 2010)

Proteomics
As part of the SFI/SBI/IRCSET-funded Bioinformatics PhD scheme, I am involved in a project developing model-based machine learning methods for biomarker discovery. The methods enable better prediction of the occurrence and severity of prostate cancers. We have recently filed an invention disclosure for this work and will shortly be submitting a patent
 
Manufacturing analytics
As co-PI of the recently funded Enterprise Ireland Innovation Partnership 'Real-time tool analytics wear analytics for medical device manufacturing' I have recently started a collaboration with DePuy Synthes (part of the Johnson & Johnson group) applying machine learning techniques to data sources from machines which manufacture medical implants. This project (in collaboration with the UCD School of Engineering) will appoint two post-docs and a PhD student.

Teaching Philosophy

 

Enhancement of Teaching

I am co-leading a project using statistics and machine learning to analyse data from the UCD Blackboard system which should allow us to identify students learning types earlier in the semester and so focus the teaching material on their specific needs. I would like to see this rolled out across UCD.

Review and Enhancement of Curriculum

I have participated fully in the recent curriculum review for all of the Data Analytics programmes and their exit strategies.

Developing as a Teacher

I have pioneered the use of blended and online teaching in the School of Mathematical Sciences since setting up the UCD Online Professional Diploma (and now MSc) in Data Analytics in 2012. These new degrees revolve around new teaching technologies through which we can provide professional quality pre-recorded material to students through Blackboard. This material is created via collaboration with UCD Audio Visual Services, UCD Teaching and Learning, and UCD online. The technologies allow us to combine live-action views of the lecturer, presentation materials, and handwritten content, essential for teaching mathematical techniques. These new ideas have been extended to our undergraduate modules to create blended teaching materials where student can access lecture material in their own time, allowing more contact time to work on problems in class.
