I am interested broadly in the evolution of communication and cognition. In my research, I examine how acoustic structure in speech is shaped by communicative goals. I have done work on infant-directed speech across cultures, vocal changes across the ovulatory cycle in women, how people use vocal signals to communicate pragmatically relevant information, and the acoustic features of other vocal phenomena.
