Her work and volunteer experiences have taken her to different parts of the world where she has worked in a variety of settings, including laboratories, industrial facilities, offices, classrooms, farms/gardens, and the wilderness including the rain forests in Costa Rica.

Ashley has a  Bachelor of Science in the College of Engineering from the University of Virginia and a Master of Science in Tropical Conservation Biology and Environmental Science from the University of Hawaii at Hilo. Her Master's program focused on stormwater management, geographic information systems (GIS), wastewater treatment science/local issues, Hawaii ecosystems and bioremediation.  

She loves troubleshooting, working with plants and collaborating with a variety of stakeholders. She hopes her work in ecological design will help to protect and enhance the beauty and natural resources of Hawaii and beyond.
