Rohini Balakrishnan is a senior professor and ecologist at the Centre for Ecological Sciences,[1] Indian Institute of Science, Bangalore. She is an expert in the field of animal communication and bioacoustics. Her research, published in renowned peer-reviewed international journals, has also received attention in Indian newspapers.[2]
Education
Rohini obtained her Ph.D. at the Tata Institute of Fundamental Research, Mumbai, India.[3] She was the first Ph.D. student of Veronica Rodrigues, an Indian geneticist.[4]
Career
She is currently a Professor at the Centre for Ecological Sciences in the Indian Institute of Science (IISc), Bangalore. Here she works on animal behaviour and acoustic communication.[5]
Listen to Rohini talk about her work on crickets (Making sense of the cacophany) here [6] at the Young Investigators' Meeting 2015 (YIM 2015) in Gulmarg, India.
