Ranjana Jaiswara (2014 - 2017)
Ranjana was the first postdoc to join BEL. She is primarily a field cricket taxonomist. At BEL, Ranjana worked on delineating species boundaries in the field cricket Teleogryllus mitratus , found all over India, and other Teleo species. In the process, we discovered a new species of Teleogryllus from Kasargod Kerala. She then worked on developing a key to Indian Teleogryllus species. This part was done in collaboration with Prof. Laure Desutter-Grandcoloas, MNHN, Paris. Together, the work was published in Zootaxa in 2021.
Ranjana is currently an INSPIRE Faculty at Panjab University.

past Doctoral students
Richa Singh (2014 - 2020)
Richa was my first Ph.D. student and she was instrumental in getting my lab set-up. Her work in BEL was on the sensory ecology of a field cricket, Acanthogryllus asiaticus. She examined how natural and aftificial light and noise at night affect the mating behaviour of the species. SHe also examined the affect of increased developmental temperature on the behaviour and survival of the species. Together her Ph.D. thesis work provides important insights into how anthropogenic changes are likely to nocturnal ectotherms. Her google scholar profile is here.

For her Ph.D. Sonam examined within call complexity, compositionality and linguistic laws in the calls of Jungle Babblers, phonology in Purple Sunbirds breeding songs and also examined heterospecific eavesdropping in non-alarm vocalizations of sympatric social Babblers. Her work has resulted i nmany novel insights in avian vocalizations that further our understanding of communicative complexity in birds. Her google scholar profile can be found here.
Sonam is currently a Postdoctoral Fellow in the lab of Dr. Raghav Rajan at IISER Pune where she continues to work on bird song complexity, but now examining the neural underpinnings of this.

Soniya helped me start the long-term project on Jungle Babblers. Her Ph.D. thesis work examined temporal variation in the behaviours of Jungle babbler, context-dependent communication, alloparental care and brood parasite recognition in this cooperatively breeding passerine. Her work is foundational to all future investigations in this species, and if the future generations of BEL will look further, it would be becasue we stand on her shoulders. You can read about her work on Jungle Babbler context-dependent vocalizations here.
