Shields's work is heavily shaped by her childhood spent growing up in a northern Texas suburb and biannual trips to visit her maternal grandmother in Ponca City, Oklahoma. Along with her mother and sister, Shields female-centric nuclear family influenced her use of photography as a way to explore themes of family, mortality and gender politics through a female-specific lens.
Shields earned an MFA from San Jose State University in California and a BA in Photojournalism from Loyola University in New Orleans, Louisiana. In 2018, her photographs received 2nd place Editor's Choice Award through CENTER Santa Fe and were selected for the PDN Photo Annual. Shields is the recipient of a 2017 New Orleans Photo Alliance grant. She works at the University of Texas in Austin, Texas.
