Carl Stenoien began pursuing a PhD in Ecology, Evolution, and Behavior with the Monarch Lab in 2012. He is studying the ecology of plant defenses across multiple trophic levels and the behavior of parasitoid wasps. Monarchs are a particularly great model system for questions in these fields because they sequester toxins from their larval host plants and are attacked by both generalist and specialist natural enemies. Carl is a graduate of Gustavus Adolphus College (2011), where he majored in Biology, minored in Neuroscience, and competed in track and field. Carl is passionate about many things, including teaching and mentoring undergraduates, advocating for long-term environmental sustainability, and the intrinsic value of physical activities.
