Dr. Cholewa studies plant structure and function. Her research interests are reflected in numerous collaborative publications, from vein arrangement and water transport in plants from Costa Rica’s rain forest to the ion and photoassimilate transport in arctic sedge. Dr Cholewa's research at Nipissing University is based on the application of a Confocal Laser Scanning Microscope in studies of signal transduction pathways in plants, allow the examinaton of responses to the environmental and chemical signals at the cellular and subcellular levels.
