Art and science exhibit “Culture as Medium” grew and evolved through its stay in Baltimore. “Culture as Medium” colonized Baltimore during April and May, 2106. An art/science exhibit curated by Margaret MacDonald, Culture as Medium brought art work done with or inspired by microbes to Baltimore. Curator MacDonald, partnered with the Baltimore Under Ground Science Space (BUGSS), Project Bridge, and Mostly Microbes to provide the perfect bacterial incubator of art and science. I stumbled onto the exhibit through my now favorite social media outlet – Twitter. Dr. Francois Lapointe, a professor of Biology at University of Montreal, Canada posted an article about his “microbiome selfies”. Reading that he’d be performing next in Baltimore, I contacted him. He quickly put me in touch with the curator of the exhibit, Margaret McDonald. “Culture as Medium” was Margaret’s brain child and thesis project for her Master’s of Fine Arts in Curatorial Practice at the Maryland Institute College of Art. Formally a chemist, Margaret became interested in the intersection of art and science.  She knew that Baltimore with its strong artistic and scientific communities was an ideal setting for an art-science exhibit.
