Dr. Patel is an expert in advanced endoscopic sinus and skull base surgery. She treats patients with a wide variety of rhinologic complaints, including chronic sinus infection or inflammation, sinus disease that has failed medical therapy, sinus disease that has failed prior surgical therapy, cerebrospinal fluid leaks, benign and and malignant sinus and skull base tumors, as well as olfactory disorders.
The research Dr. Yvonne Maldonado has conducted has been focused on epidemiologic aspects of viral vaccine development and prevention of perinatal HIV transmission. A major project has been to identify the molecular epidemiology of factors affecting the immunogenicity of oral polio vaccine (OPV) among children living in developing areas of the world, where OPV immunogenicity is poor. Dr. Maldonando's group has identified several factors which affect the poor immunogenicity of OPV and will conduct clinical studies to attempt to improve immunogenicity.
One of Dr. Yueh-hsiu Chien's main research focuses is to define γδ T cell function so that we can better understand host immune defense. γδ T cells, together with B cells and αβ T cells, are the only cells that use somatic V, D, J gene rearrangement to generate diverse antigen receptors. All three types of cells are present together in all but the most primitive vertebrates, suggesting that each population contributes to host immune competence uniquely and that all three are necessary for maintaining immune competence.
