Priyanga Dilini Talagala

PhD in Statistics

Monash University, Australia

I am a Senior Lecturer in the Department of Computational Mathematics, University of Moratuwa. I earned my PhD in Statistics from Monash University, Australia, under the supervision of Professor Rob J. Hyndman and Professor Kate Smith-Miles. I am a fellow of OWSD, a programme unit of UNESCO (2021-2022).

I am an Associate Editor for The R Journal. Further, I am a co-founder of R-Ladies Colombo, a local chapter of the R-Ladies Global Organization.

My research focuses on statistical machine learning and data mining, and in particular the development of novel methods and tools for analyzing complex data. I am also strongly committed to developing open source software tools to facilitate reproducible research. You can find some of my projects here. Visit me on twitter, I post mostly about R, Statistics, Data Science and science in nature.

I am an Associate Investigator of the Australian Research Council (ARC) Centre of Excellence for Mathematical and Statistical Frontiers (ACEMS), Australia, 2019 - 2021.

Thiyanga Talagala, PhD in Statistics, Monash University, Australia is my sister.
