Rohini Balakrishnan is an Indian bioacoustics expert. She is a senior Professor and Chair of the Centre for Ecological Sciences at the Indian Institute of Science (IISc), Bengaluru. Her research focuses on animal behavior through the lens of animal communication and bioacoustics.[1] [2]

Education and career

Rohini Balakrishnan has a bachelor's degree in Biology and a Master's in Zoology. She received her PhD in behavior genetics in 1991 from the Tata Institute of Fundamental Research (TIFR) in Mumbai, India. She was the first Ph.D. student of Veronica Rodrigues, an Indian geneticist.[3] [4] She then moved into the field of behavioral ecology, studying acoustic communication in animals and carried out postdoctoral research at McGill University, Canada, from 1993 to 1996, followed by a second postdoc at the University of Erlangen, Germany (1996-1998). She joined IISc, Bangalore in 1998 where she is currently Professor and Chair of the Centre for Ecological Sciences.

Research

Balakrishnan's current research is aimed at understanding the causes and consequences of animal behavior using acoustic communication. Her lab studies behavior and the ecological pressures that shape behavior in several field sites located in the tropical forests of southern India.[5] This work is primarily focused on crickets and bats in the Kudremukh National Park, elephants in Mudumalai Wildlife Sanctuary[6] and songbirds at the Biligiri Rangaswamy Temple Sanctuary.[7] Her lab was the first to study vocal communication in the greater racket-tailed drongo.[8] Using acoustic communication and behavior, her research explores several themes: signal mechanics and physiology of the sound-producing cricket and the auditory behavior of the receiving insect. Her work also looks at the foraging strategies and predator-prey interactions as well as reproductive choices and mate selection.[9] In addition to research, she is also interested in developing and validating databases of acoustic signals of various species to facilitate identification. This enables periodic biodiversity monitoring using an automated recorder installed in an environment allowing for non-invasive sampling. Her team has built libraries of over 200 elephant calls and recording over 90 species of birds.

Legacy

Two species of cricket discovered in Mexico and in Kerala, India have been named Oecanthus rohiniae and Teleogryllus rohini in her honor.[10] [11]  Balakrishnan has also discovered several new species of crickets including Prozvenella bangalorensis at the IISc campus in Bangalore.
