Making with attention
… through the guise of utilitarian objects. By using materials that have been classified as waste to create sculptural works I bring value to something that had little. I use low-tech and old-world methods to create, allowing myself to experience the true labor inherent in the making of things, …

conceptual packaging
… charming because of the delicate selection of materials, images, and interaction. Different kinds of material provide different emotions and appeal to our sense of touch, which can be interpreted in many ways. Packaging lets us directly interact with an object and this experience becomes …

Living reading: The mutual construction of spirituality and reading
"Using materials gathered from a one and one-half year ethnographic study of several local affiliates of the Illinois Reading Council, the author explores the multiple meanings of reading that emerged from the group's practice, to develop the notion of ""living reading."" The dissertation provides …
