Hanna Schneeweiss is a Professor at the Department of Botany and Biodiversity Research , University of Vienna. Her work focuses on plant evolutionary biology, cytogenetics, and systematics, with particular emphasis on chromosomal evolution, hybridization, and biogeography. Current Teaching: Courses include Plant Chromosome Structure, Genome Evolution, and Systematic Botany Research Themes: Chromosomal speciation, polyploidy, and ecological-genomic interactions Her recent research explores the interplay between chromosomal changes and species diversification across multiple plant lineages. A recurring theme in her publications involves analyzing repetitive DNA elements, karyotype dynamics, and phylogenetic relationships in polyploid complexes. Key trends in her work include: Investigating chromosomal evolution in genera like Melampodium , Dactylorhiza , and Prospero Developing molecular cytogenetic techniques such as formamide-free genomic in situ hybridization Integrating biogeography with genomic data to understand long-distance dispersal patterns
