Christian has been working with the conservation of plants since 2005 when he was an undergraduate student of horticulture at the University of Puerto Rico (UPR) at Mayagüez and a Biological Science Technician at the U.S. Fish and Wildlife Service. His work consisted of leading reforestation efforts and assisting with the monitoring, mapping, and propagation of endangered plants in Puerto Rico and the U.S. Virgin Islands. In 2010, Christian earned a Master’s degree in Botany from the University of Hawai’i at, and simultaneously, was a botanist student trainee for the USFWS and completed a 3-month plant conservation internship with the National Tropical Botanical Garden. Among his most remarkable accomplishment during his tenure in Hawai’i was securing funding to expand the Hawai’i Plant Extinction Prevention Program to the island of Kaua’i, where hundreds of endangered plant species occur. Working hand-by-hand with Hawaiian botanists, Christian was trained in field botany, plant systematics, genetics, ecology, pollination biology, and ex situ and in situ conservation.
Since 2014, Christian has been the Director of Arboretum Doña Inés Park of the Fundación Luis Muñoz Marín, a native plant arboretum in San Juan focusing on conservation education, research, and ex situ management of the flora of Puerto Rican and the Caribbean. Since his appointment, the arboretum has dramatically increased in partnerships and has been involved on plant conservation and botanical garden conservation and education programs. Christian is a firm believer in teamwork and has collaborated with multiple agencies and institutions to promote and implement conservation programs for endangered plants. His easiness to communicate with others and charismatic personality has attracted the attention of general public, resulting in an increase on visits to the arboretum from 3,000 to over 15,000 persons per year.
