From 1886 she worked as a teacher there in a wide range of subjects including English, History, Logic, Ethics, Latin and Botany.

In 1882 she was involved in the founding of the Central Association of Irish School Mistresses to support education for girls and to ensure access to university, hence her resolve in the fight for admission to Trinity College Dublin.

Conservative legal advice was issued to the college, which effectively blocked the admission of women and the campaign lost impetus by 1895.

In 1902, she became the first president of the newly formed Irish Association of Women Graduates who worked to achieve coeducation in higher education in Ireland.

An effective advocate of the claims of women in all walks of life, she will be deservedly remembered for the splendid work which she rendered to the higher education of women.Posthumously, in 1909, a book of her lectures entitled An Introduction to the study of Philosophy was published.
