His Tehran University dissertation dealt with Persian poetry under the Timurid Shahrukh (15th century). His University of London dissertation, elaborated and published later as A Grammar of Southern Tati Dialects (Mouton, 1969), describes a series of Tati dialects spoken in the southwest of Qazvin. He had published a number of articles on modern western Iranian dialects, notably Tati and Taleshi, and the Jewish dialects of Persian (including Lotara'i), and on Persian mythology. His parents were Iranian Jews who had converted to the Baháʼí Faith, but he had no affiliation with the Baháʼí Faith as an adult.
