Dr. Gold studies protozoan parasites that reside within specialized vacuoles inside or attached to their host cells. Parasites that adopt this lifestyle include those responsible for causing such serious diseases as malaria, toxoplasmosis and cryptosporidiosis. He is interested in understanding the complex “molecular dance” of host-parasite interactions critical to developing drugs and vaccines that might cure or control these diseases.

Dr. Gold teaches Molecular Genetics, Cell Biology, Parasitology, and Immunology at St. Edward’s University. Before joining the St. Edward’s faculty, Dr. Gold studied molecular host-parasite interactions of Toxoplasma gondii during his Postdoctoral studies at MIT and subsequently as a research scientist at UC Davis. Prior to studying parasitology, his doctoral research at Caltech focused on the DNA damage and replication checkpoints. At St. Edward’s, Dr. Gold's focus is on developing molecular tools to study the highly diverse but relatively understudied class of protozoan parasites of invertebrates called Gregarines. This work involves a combination of cell biology, molecular biology, biochemistry and research in the field to collect wild isolates of these parasites.
