Biography

Wray is a Professor in the Faculty of Information Technology at Monash University in Melbourne, Australia.

He enjoys playing with web/text data and writing code, and supports some of his work on Github (wbuntine). His research interests include theoretical and applied work in document and text analysis, machine learning, and probabilistic methods including:

  • discrete non-parametric Bayesian statistics
  • latent variables in semi-structured and text analysis
  • topic models for semi-structured data
  • probabilistic interpretations for deep neural networks
  • applications in medical and health infomatics. 

He teaches Data analysis for semi-structured data (FIT5212) and formerly taught Introduction to Data Science (FIT5145) and Modelling for data analysis (FIT5197).  He was founding director of the Master of Data Science, see the introduction to new students at Youtube.
