As Director of the Laboratory of Human Parasitology, Dr. Mejia’s research interests include molecular diagnostics of neglected tropical diseases and host defense mechanisms, specifically on gastrointestinal parasites such as Strongyloides. Locations of research and collaborations include USA, Mexico, Honduras, Ecuador, Colombia, Argentina, Mozambique, and Uganda. The Diagnostics unit is dedicated to using modern molecular methods to detecting parasitic infections in patients. We are currently investigating gastrointestinal parasites including soil transmitted helminths (STH) Ascaris lumbricoides, Ancylostoma duodenale, Necator americanus, Strongyloides stercoralis, Trichuris trichiura and protozoans Giardia lamblia, Entamoeba histolytica and Cryptosporidium hominis/parvum. Our patient populations include immigrants, travelers, and indigenous people from field studies around the world. Our goals are to further define the prevalence and parasitic burden in endemic populations with goals of eradication and improvement healthcare outcomes.
