Dr. Gyorkos has been a researcher in parasite disease and infectious disease epidemiology for over 20 years and has conducted population-based primary epidemiological field research both in Canada and abroad. Her Canadian-based research focuses primarily on infections in child and educator populations in the daycare setting and imported and endemic parasite infections in at-risk populations (eg. immigrants, travelers). Her international health research activities centre mainly on:
1. Helminth control programs in high risk population subgroups (eg. school-aged children and pregnant women);
2. Multidisciplinary approaches to the prevention and control of endemic infectious and parasitic diseases; and
3. Reducing health inequalities in communities of extreme poverty.

She spent her sabbatical year from 1998-99 at WHO with the Schistosomiasis and Intestinal Parasite Unit (SIP), where she participated with this group in developing a WHO policy on helminth control programs targeted to school-age children which was ratified at the 2001 World Health Assembly. Together with her WHO colleagues she has since co-authored a manual on Monitoring Helminth Control Programmes (1999) and a book on Helminth Control in school-age children which is a guide for managers of control programmes (2002). She is a member on WHO’s Expert Advisory Panel on Parasitology. Her current sabbatical year (2006-2007) is based primarily in Peru and Mexico.
