My research uses mathematical, statistical and computational methods to answer fundamental and applied conservation questions in biodiversity science, evolutionary biology, ecology, genomics and bioinformatics, as they relate to molecular species identification and discovery through DNA barcoding and other DNA-based approaches.
- Agent-based, compartmental, and individual-based modelling
- Bayesian computing and statistics in R and Stan
- Biodiversity informatics (e.g., DNA barcoding, environmental DNA (eDNA) DNA sequences analysis)
- Data science
- Machine learning (e.g., association rule generation, clustering, classification, and dimensionality reduction of (e)DNA sequence data and related metadata)
- Nonparametric statistics (e.g., bootstrap resampling, local regression, kernel methods)
- Spatiotemporal modelling (e.g., conditionally autoregressive models (CARs)
- Gaussian processes (GPs)/Kriging, generalized additive models (GAMs), time series)
- Stochastic optimization (e.g., random search algorithms, genetic algorithms (GAs), simulated annealing)
