Within the recent past he has had solo exhibitions at the Evanston Art Center, Quincy University, Expressions Graphics and the Ellwood House Museum, all in Illinois. Recent group exhibitions include the Birds in Art show in Wausau, Wisconsin, American print surveys in Kansas and Indiana and a show at Chicago's Union League. His woodcuts were featured in a three-person exhibition entitled Nature As Metaphor with venues in Ohio and Illinois.

Other professional activities include giving numerous lectures and printmaking demonstrations as well as contributions to national portfolios and journals. He is the recent recipient of a grant from the Illinois Arts Council, a state agency.

A growing interest in birds has lead Peter around the country to observe and draw new species. In January 2000 he began The DeKalb Migratory Bird Project, an ongoing exploration of his combined interests in art and science. His illustrations of birds have been used in several ornithological journals, and for the cover of a book, Stuffed Animals and Pickled Heads: the Culture and Evolution of Natural History Museums, published by Oxford University Press in 2001.
