Stella Y. Sun’s research is focused on addressing important scientific and biomedical problems, particularly in pathogen-host interaction from structural and molecular cell biology perspectives. My lab is dedicated to the experimental and computational application of cryo-ET for structural determination of biological macromolecules or biological machinery in single-celled parasites that cause important human diseases. I am particularly interested in understanding the molecules transportation, organelle biogenesis and their regulations in the invasion process of the malaria parasites (or related apicomplexan parasites) and the migration of Trypanosoma brucei that causes African sleeping sickness in humans and Nagano in cattle. Our research is to visualize the organization of cellular structures and their coordination in 3D spatial organization through a multi-scale imaging platform ranging from microns to sub-nanometers, to elucidate the molecular and structure functions that drive cell migration or invasion. Crucially, the novel cryo-ET analysis developed will also broadly enable the study of molecular machines in other complex biological contexts.
