I'm a second year Palau Community College student majoring in Environmental/Marine Science program. I'm doing my internship and field study at the Belau National Museum under Entomologist Alan R. Olsen. I'm doing a project on aquatic insects as environmental indicators. I want to be a aquatic entomologist someday!
