Kaiya (she/her) grew up in the Adirondack mountains of upstate New York and spent her childhood exploring the woods and lakes of the northeast. She moved to Saint Petersburg, Florida, to attend Eckerd College where she graduated with a BA in Psychology and minors in Environmental Studies and Human Development. She then worked as an environmental educator before becoming a wildlife rescue and rehabilitation specialist. After seeing so many animals harmed by preventable human causes, she decided to attend graduate school to work towards changing detrimental patterns of human behavior.
Her master’s thesis with Dr. Rebecca Niemiec in the Human Dimensions of Natural Resources Department at CSU focused on the social psychological drivers of native plant gardening behavior, working to understand how to encourage residents to use native plants to conserve biodiversity, support pollinators, and reduce water use, among other benefits. Kaiya has come to believe that the root of sustainable behavior change lies in our connection to the natural world. As a Ph.D. student with Dr. Sarah Walker she will explore how higher levels of nature connectedness can improve both human and environmental well-being. Her goals are to use applied methodologies and a lens of environmental justice to connect people to the outdoors and increase equity for people and the planet.
