Dr. McCarty has been a PAHO/WHO Scholar since 2007. Her work focuses on Community Health and Child Health. She has been co-investigator on a Sparkman Center for Global Health funded grant called “Building a Partnership for Collaboration in Nursing Research in Honduras”. She was also instrumental in securing the "Familias Fuertes" grant on which she was co-investigator.
