Aleu completed her studies in 1879, but she didn't receive permission to take the licensing exam until nearly three years later, in the spring of 1882.

[9] On 8 October 1882 Aleu became just the second Spanish woman to earn a doctorate in medicine (she received her MD a few days after Martina Castells Ballespí).

[6] Her thesis, presented on October 6, was titled On the need to set the hygienic and moral education of women on a new course, and supervised by Professor Joan Giné i Partagàs, dean of the Faculty of Medicine and rector of the UB.

[10] Aleu was also the author of informative texts aimed at improving the quality of life for women, especially mothers.

These included Advice to a Mother on Management, Cleaning, Clothing, Sleep, Exercise, and Entertaining the Children.

[2] In addition to her own practice, Aleu worked as a general practitioner free of charge at Barcelona’s poor house, the Casa de la Caritat.
