Irena Kaczmarska

Irena Kaczmarska is a Research Professor in the Department of Biology at Mount Allison University. Her work focuses on diatom biology, particularly sexual reproduction, auxospore development, and evolutionary adaptations. She investigates siliceous microfossils and modern diatom species, contributing to taxonomy and biogeography.

Research interests span reproductive mechanisms, biomineralization, and phylogenetic relationships in diatoms. Her studies often combine microscopy, molecular tools, and fieldwork to address evolutionary and ecological questions.

Publications highlight auxospore structure, sexual dimorphism, and diatom responses to environmental pressures. She has described novel species and contributed to understanding diatom diversification strategies.
