Research Interests: Our lab studies orchid fungal associates, pollination biology, and seed germination with an overall goal of successfully re-introducing plants into native populations to support orchid conservation. Our recent work has focused on fungal collection and identification. We have collected fungi from orchid roots across the Midwest. Fungi from these plants can be established into new areas, potentially providing new habitats for terrestrial orchid species. We have also been working on understanding native orchid pollination biology. The lab has attempted hand pollinations of flowers to determine if pollen limitation is present and leading to decreased seed set.

Research Opportunities: Students who wish to learn more about research opportunities are encouraged to contact me.
