Dr. Ellen Lake is a Research Entomologist at the USDA ARS Invasive Plant Research Laboratory in Fort Lauderdale, Florida. Her first experience with invasive plants involved battling thickets of multiflora rose in southeastern Pennsylvania. Ellen graduated from Bryn Mawr College where she majored in Biology and Anthropology and worked as a field assistant researching biological control of purple loosestrife. She then taught environmental education at the Brandywine and Red Clay Valley Associations and served as their Education Director. Ellen completed her graduate studies at the University of Delaware researching biological control of mile-a-minute weed (Persicaria perfoliata) and methods to integrate biological control, herbicide applications, and plantings of competitive native species to restore invaded sites. She began working in Florida in 2012 as a post-doctoral researcher at the Invasive Plant Research Laboratory. Here, she works primarily with air potato and Old World climbing fern, including conducting host range tests, investigating establishment and impact, assessing indirect effects of weed biological control, integrating weed management techniques, and using drones to release biological control agents.
