[1] After receiving an exchange fellowship from the American Swiss Foundation the following year, Narbel studied zoology at Columbia University in the United States.

[1] Narbel's research focused on cytogenetics, and her study of the process of meiosis in parthenogenic animals was described as being "a modern classic".

[6] In 1970, Narbel was elected to the Grand Council of Vaud, representing Lausanne as a member of the Liberal Party of Switzerland.

[1] At some point, Narbel was married to Jean-René Hofstetter, who was the director of the Lausanne University Hospital, though they had no children and eventually divorced.
