Oier began painting later in life in an attempt to project herself outside of her traditional household roles. Her work focuses on exploring life through the process of painting; inspired by politics, culture studies, war, separation, homemaking, and social constructs. Her goal is to maintain work that is brutally honest. In this attempt, her work often communicates culturally taboo subjects, demonstrating confusion, isolation, aggression, obsessiveness, and satire. Process is a driving force in her work, creating a dirty, labored, and often overworked feeling. Her goal as an artist is to contemplate complex subject matter, bridge cultural/political gaps, and analyze society (through distorted eyes).
