Gretchen's research interests include the effects of cultural variation on non-parental caregiving of children and other vulnerable adults, and fosterage and adoption. She has conducted field work in rural Bangladesh using qualitative and quantitative methods from epidemiology and ethnography, as well as structured interviews.
Gretchen's research has focused on the "matrilateral bias" (the persistent pattern of mother's extended family investing more in children, on average, than father's extended family) found around the world. She has more recently been involved in research related to conflict in the family and spousal and familial homicide in New Zealand.
