My research interests include:

• Development of general and logically consistent dissimilarity based approaches and metrics for measuring and decomposing genetic, functional, and phylogenetic variability to address a wide range of topics in Population Genetics, Ecology, and Conservation.
• Analyzing structural relationships of operational units at different hierarchical levels of biological organization and at various spatiotemporal scales.
• Measuring dissimilarity between individual profiles for different types of organisms and markers, and dissimilarity based distances between operational units at higher hierarchical levels.
• Population Genetics of Plant Pathogens with an asexual or mixed mode of reproduction.
• Development of Computational Tools for Diversity Analysis.
• Modeling Plant Pathogen Epidemics and systems of Plant Protection.
