Lidia Wojtczak is interested in the Sanskrit language and its teaching — both in its South Asian contexts over time, and in the West. She works on Sanskrit poetry (kāvya), and theoretical texts on poetics and aesthetic practices in pre-modern South Asia.

Her main focus is Sanskrit messenger poetry (dūtakāvya), and she is currently editing and translating a set of Sanskrit messenger poems from Kerala in South India. These poems form a coherent and distinct corpus, significant for both local and translocal practices of Sanskrit composition.
