I work on the mathematical practices testified by Sanskrit treatises and commentaries of the 5-12 centuries.
I am currently working on a critical edition of Caturveda Pṛthūdakṣvamin (fl. 860 )’s commentary on the mathematical chapter of the Brāhmasphuṭasiddhānta.

I also explore 19 and 20th century histories of mathematics in India written outside and within the Indian subcontinent, underlying notably their political context. I am also interested in the way critical editions and translations of mathematical texts were elaborated and then circulated and read and the influence this has had on present day historiographies.
