She received her MFA from the University of New Orleans and currently lives there. Stewart has gained national recognition for her paintings and has been awarded several artist fellowships and grants, such as the Louisiana Division of the Arts in 1988, Louisiana Endowment for the Humanities in 1997, and the Mary Freeman Wisdom Foundation Grant in 1995. In 2005 she was awarded an Artist in Residence position at Anderson Ranch Arts Center in Colorado.
Stewart is inspired by increasingly fragile environments and the interconnectedness of all living things. She uses layers of color, light, form and texture to address issues of beauty and loss, time and transformation. Residing somewhere between realism and abstraction, the paintings become visual diaries upon which Stewart records her responses to the threatened landscape.
