Charlotte Song has been interested in living things her whole life. She took a life science class in seventh grade that inspired her to become a scientist. She received bachelor of science degrees in biology and geography from the University of Maryland Baltimore County. Throughout her undergraduate career, she worked as an intern at the USDA Agricultural Research Service doing research with plants, including work improving farming and developing disease resistant crops. She went to graduate school at the University of Texas at Austin, receiving her PhD under the supervision of Dr. Stanley Roux. She worked on the role of extracellular ATP as a novel signal in plants. She did her research with the model species, Arabidopsis thaliana. Dr. Song continued her work in signal transduction by studying MAP kinase cascades in guard cell movements at the University of Maryland as a postdoctoral fellow. She did a second postdoctoral fellowship at DuPont working with small RNAs. She studied the role of micro RNAs in translational regulation in plants. She teaches Botany and Introduction to Biology for nonmajors at Charleston Southern University.
Dr. Song is currently studying the factors that switch a micro RNA target from being regulated by cleavage to being translationally regulated. Micro RNAs are small RNAs that have been studied extensively but were only discovered recently. They have been found to have profound effects in development and regulation in plants and animals. Dr. Song made a mutant population of Arabidopsis thaliana and screened individual plants for loss of translational regulation. She works with undergraduates in her laboratory characterizing and mapping the mutants.
