Malaria caused by Plasmodium falciparum remains one the most serious infectious diseases infecting over 200 million people and causing nearly 500,000 deaths every year, mostly in young children in Sub-saharan Africa. Clinical disease is caused by the exponentially growing parasites within the red blood cells (RBCs). We study the dynamic processes regulating successful parasite entry into and exit from host cells. Our goal is to better understand the molecular mechanisms regulating important biological processes outlined below. To address these questions we use complementary approaches encompassing conditional genome editing techniques, live cell imaging, high throughput screening, biochemistry and proteomics.

1. Understanding receptor-ligand interactions and the signaling mechanisms mediating parasite invasion: Successful parasite entry into host cells requires a sequence of receptor-ligand interactions, each responsible for a specific step in invasion. We study the signaling mechanisms that regulate the precise spatial and temporal secretion of parasite ligands and how these interactions shape the fate of the invading parasite.

2. Parasite induced modifications of the host cell: We are investigating the molecular interactions between the parasite and the host cell cytoskeleton that facilitates parasite entry without causing damage to the host cell.

3. Malaria vaccine development: We apply our understanding of how proteins function during parasite invasion to identify new vaccine targets and improve the design of existing antigens.

By studying the key factors and the mechanisms by which they regulate host cell egress and invasion, we seek to open new paths for the development of novel intervention strategies to block invasion and prevent disease.
