Richard McCourt’s research is on the biodiversity, evolution, ecology, and systematics of green algae, specifically a group known as charophyte algae. These green algae are among the closest living algal relatives of land plants and include some well-known algae such as stoneworts and Spirogyra. He is working on reconstructing the phylogeny of these algae-that is, the evolutionary tree of green algae and land plants. A comprehensive phylogeny of green algae will help explain ancient evolutionary events that allowed the descendants of green algae to emerge from their habitats in freshwater ponds and diversify into the hundreds of thousands of species that live on land today.
McCourt has also conducted research on the ecology of intertidal algae in the Gulf of California, Sonora, Mexico. He studied habitat partitioning and phenology (seasonal patterns of growth and reproduction) of sympatric species of Sargassum, large brown seaweeds that occur in huge floating masses in Atlantic gyres, as well as in subtidal and intertidal areas in the subtropics and tropics. He has also worked in historical botany, publishing a number of papers on the Lewis and Clark Herbarium at the Academy, and he co-authored with Earle E. Spamer a Special Publication CD-ROM and a short book on the Lewis and Clark Herbarium.

Rick McCourt, PhD has worked at the Academy since 1997. Before that he was an associate professor at DePaul University in Chicago, where he taught algal biology, aquatic biology, ecology, evolution and introductory biology. McCourt is Curator of Botany at the Academy of Natural Sciences of Drexel University in Philadelphia.
Rick McCourt, PhD, is Chair of the Board of Trustees of the Phycological Society of America (psaalgae.org), and also serves on the Publications and Financial Advisory Committees of the Botanical Society of America.
Previous to joining BEES, McCourt worked at the National Science Foundation as Program Director in the Division of Biological Infrastructure (Collection in Support of Biological Research, Major Research Instrumentation, Living Stocks Collections), the Division of Environmental Biology (Systematics and Biodiversity Science Cluster), and the Division of Graduate Education (NSF Graduate STEM Fellows in K-12 Education [GK-12], Graduate Research Fellowship Program). He also served on the Interagency Working Group on Scientific Collections and co-authored a report on NSF-supported collections (Skog, J., McCourt, R.M., Corman, J. 2009. The NSF Scientific Collections Survey: A Brief Overview of Findings). He was on the working group for Advancing Digitization of Biological Collections at NSF (ADBC).
