Biography

Janice Scealy is a research Statistician specialising in the analysis of complex structured datasets. Janice's research interests include: compositional data analysis; directional statistics; shape analysis and statistics for manifold-valued data; robust statistics; statistics in the Earth Sciences; applications in palaeomagnetism, seismology and geochemistry; geostatistics and the analysis of spatial data; and model selection in linear mixed models. Janice’s research appears in leading academic journals including Journal of the American Statistical Association, Journal of the Royal Statistical Society Series B, Statistical Science, Statistics and Computing, International Statistical Review, Australian and New Zealand Journal of Statistics, TEST, Journal of Geophysical Research: Solid Earth and Geophysical Journal International. Janice was awarded the Moran Medal in 2021 by the Australian Academy of Science. Janice has also achieved previous major grant success which includes two Discovery Projects (one in the Mathematical Sciences and one in the Earth Sciences), and a Discovery Early Career Researcher Award. Janice is listed as one of 60 historical and prominent Australian Statisticians (Significance Magazine).
