Ashwini Deo received Masters degrees in Sanskrit Grammar and Linguistics from Pune, India followed by a PhD in Linguistics from Stanford University in 2006. She is now an Associate Professor at Yale University, where she has been since 2006. Her main research interest is in systematic semantic change phenomena — particularly in the ways in which functional morphemes like tense-aspect, negation, possession markers change over time. Within semantics-pragmatics she also works on phenomena in the domains of aspect, temporal reference, lexical semantics of verbs, and genericity. Her empirical focus is on the Indo-Aryan languages, which are spoken in much of South Asia, and which provide us with a diachronic linguistic record of over 3000 years.
