Much of her research looks at aging and retirement, with a focus on women and LGBTQ populations. In particular Dr. Gambold has looked at that growing trend of single retired women, more than single men, choosing to settle in a foreign country. Economic concerns are often the driving force behind their decision. The cost of living in Canada, the United States or England can be quite high, pensions can be threatened, and women outlive men. So an international retirement becomes a viable strategy for those women concerned about living off their pensions at home.
