I am a Lecturer/ tenured-Asst. Professor (as in United States). My research expertise are in modelling and methodology statistical analysis of time series and spatial processes. I investigate natural events that evolve over space and time. Of particular interest are landslides, tropical cyclones, river flow, and human diseases. The statistical problems are wide rannging and complex.

Current Interests

My immediate interests fall into the following categories-

Statistical Methodology

1. Modelling of spatial and temporal covariance structures.
2. Computational and statistically efficient models for natural hazards.
3. Interface of maximum likelihood and interpretable machine learning algorithms for streaming data.

Applications

1. Algorithms for landslide monitoring.
2. Methods for detecting structural changes in neurological time series.
3. Statistical variation in river flow and tropical cyclones.
4. Spatial variation in tropical ecological process.
5. Spatial epidemiology for infectious diseases and mental health.

If you wish to pursue a PhD with me or want to discuss some of my current research interests please contact me at sourav.das@jcu.edu.au. I am particularly keen to hear from students with background in one or more of the following- statistical analysis of time series, applied stochastic process, multivariate statistical methods, mixed effects modelling or spatial statistics.
