[10] With his former students Lennart Bes and Gijs Kruijtzer he produced the archival inventory Dutch Sources on South Asia c. 1600-1825.
[11][12] In the early 2020s he cooperated closely with Said Reza Huseini in writing various research articles on the global intellectual history of Islamic Neoplatonism and the Mongol legacy in particular pertaining to the Mughal emperor Akbar.
[14] Building on the initiative of his Leiden predecessor Leonard Blussé, Gommans spearheaded several programmes that trained over 150 students from Asia and South Africa at the BA, MA, and PhD levels.
Between 2000 and 2025 these programmes (TANAP, Encompass, Cosmopolis and Cosmos Malabaricus) aimed to equip students with the skills to work with Dutch colonial archives, fostering a deeper integration of these sources into the regional histories of Asia and Africa.
[15][16][17] In 2019 Gommans acted as the Rijksmuseum guest curator of the 2019 exhibition “India and the Netherlands in the Age of Rembrandt” at the Chhatrapati Shivaji Marahaj Vastu Sangrahalaya in Mumbai.
