Current Research:
Most plants form obligate relationships with symbiotic fungi termed mycorrhiza. Orchids are the largest group of flowering plants and require fungi for germination in nature. As adults, they form a specific type of mycorrhiza and rely on the fungus to acquire additional nutrients. My research focuses on fungal ecology, in particular, the interactions between mycorrhizal fungi and orchids. My current research includes the investigation of leafless epiphytic orchids of south Florida. I am doing research at the Florida Panther National Wildlife Refuge that focuses on the rare and endangered epiphytic orchid Dendrophylax lindenii (the ghost orchid).
My previous research investigated the mycorrhizal fungi associated with Vanilla planifolia, an economically valuable crop with pods responsible for the flavor vanilla. Vanilla planifolia is hemiepiphytic with both epiphytic and terrestrial roots. My field sites are at V. planifolia plantations in Mexico. The objectives of my research are to: 1) elucidate the microbiome of V. planifolia epiphytic and terrestrial roots; and 2) characterize how various farming practices (wild natural, traditional and highly managed) influence mycorrhizal communities found in the roots of V. planifolia.
