Xiaotian Zheng

I am Research Fellow (postdoc) at the Centre for Environmental Informatics (CEI) in the National Institute for Applied Statistics Research Australia (NIASRA) at the University of Wollongong. My research at CEI, with Noel Cressie and Andrew Zammit Mangion, involves developing new statistical methods for understanding and predicting Antarctic biodiversity, as well as data fusion and statistical downscaling for regional climate variables with uncertainty quantification. The research is part of the Securing Antarctica’s Environmental Future (SAEF), an Australian Research Council (ARC) Special Research Initiative that aims to understand, manage, and forecast the environmental changes taking place across the Antarctic region.

My research interests broadly lie in parametric and nonparametric methods for complex and dependent data. Currently my research focuses on spatial and spatio-temporal statistics, statistical downscaling and data fusion, point process modeling, mixture models, uncertainty quantification, and transfer learning, with applications in ecology, climate change, and the environmental sciences. I am also interested in methods for high-dimensional data and scalable algorithms for large data sets.

I received my Ph.D. in Statistical Science in 2022 from the Department of Statistics at the University of California, Santa Cruz, where I worked on mixture modeling for non-Gaussian spatial and temporal processes, advised by Athanasios Kottas and Bruno Sansó.
