Research Interests:

My research interests include phylogeny, evolution of parasitic plants and host selection, taxonomy of mistletoes (Loranthaceae, Viscaceae, Santalaceae), island biogeography and biodiversity, pollination biology, conservation biology, and taxonomy of Neotropical plants, especially in the Caribbean region. My dissertation research investigates the phylogenetic relationships of an endemic group of mistletoes from the Caribbean (Dendropemon in Loranthaceae), including a taxonomic revision of the genus and examining possible factors influencing host selection and speciation. I am using multiple transcriptomic datasets to build high resolution phylogenies at species level for Dendropemon and other related genera within the subtribe Psittacanthinae.

Other Interests:

My other interests include reading, hiking, traveling, learning new languages, sports, cooking, and doing volunteer work at the Penn State PAC Herbarium.
