Az (Ashley A.) Klymiuk

Collections Manager, Paleobotany

Gantz Family Collections Center

Dr. Az Klymiuk is a Métis Canadian botanist, mycologist, and paleontologist. Their research comprises comparative plant anatomy of gymnosperms and morphological systematics of fossilized microfungi.  In the course of their doctoral work at the University of Kansas, they became interested in plant-microbe interactions in dynamic redox systems that characterize wetland soils, and has worked to understand how the ecology of living root-associated fungi is impacted by these harsh biogeochemical conditions.  At the Field Museum, they are the collections manager for Paleobotany.
