Isha Bopardikar I am a visiting researcher and a volunteer at the K. Lisa Yang Center for Conservation Bioacoustics. I have been studying marine mammals in India since 2012 and my research has primarily focused on the acoustic communication of coastal cetacean species. I first visited the Yang Center in the fall of 2015 to attend the Sound Analysis Workshop. Following the workshop, I spent a month at the Yang Center to analyze humpback dolphin recordings from the northwestern coast of India.
My current study aims to describe the vocal repertoire of Indian Ocean humpback dolphins and explore behavioral context of acoustic communication. Subsequently, I will use passive acoustic monitoring to study habitat use and spatiotemporal occurrence patterns of this species in areas with a high degree of anthropogenic pressure. Apart from this, I am also interested in outreach and science education. Additionally, I volunteer with the Teach for India program.
