Juniper Simonis was a research scientist at Lincoln Park Zoo’s Alexander Center for Applied Population Biology from 2013–2015 before moving into their current role.
As an undergraduate student, they conducted research on enzyme production by aquatic fungi and parasite-host dynamics in Daphnia (water flea). Following a year off from school, which they spent as a technician in a plant-insect lab at Florida State University, Juniper began their Ph.D. studies at Cornell University in 2007.
Working with Nelson Hairston Jr., Ph.D., in the Department of Ecology and Evolutionary Biology, Juniper studied how dispersal and trophic interactions combine to determine the dynamics of populations in spatially fragmented landscapes. Their thesis consisted of observational, experimental, and theoretical studies and was focused on a system of freshwater rock pools on Appledore Island, Maine. The rock pools provided a fantastic field system to study how populations and food webs persist in naturally fragmented habitats. While in grad school, Juniper also developed and taught a graduate-level course and multiple workshops on statistical programming. Juniper completed their dissertation (titled “Food Webs in Space!”) in January 2013 and promptly moved back to Illinois. In 2015, Juniper moved to Portland for new opportunities, but they continue to collaborate with Lincoln Park Zoo scientists on key initiatives.
