PhD and Postdoc Alumni

Former Postdocs
anindita-dasAnindita Das did a short postdoc in our lab from August 2017 to Jan 2018. She is integrated  interest ined the mechanistic underpinnings of behaviour. She did her PhD on the neurophysiological basis of learning and memory as part of my thesis (advised by Prof Rishikesh Narayanan, MBU, IISC) using a combination of computational modelling and electrophysiology. After submitting her thesis, she worked in her lab as a Research Associate delving into the ecological basis of behaviour, learning methods of ecological modelling to understand heterospecific sociality. She then moved to her postdoctoral position with Prof Jesse Goldberg at Cornell University.

Karpagam Chellaiah did her PhD in ecology at the Centre for Ecological Sciences working on Asian elephants with Prof R Sukumar. She did a joint postdoc with Dr Maria Thaker (CES) and Dr Srikanth Iyer (Math department), working on analyzing elephant movement data from Africa. Duration: Jan 2014 to July 2016.

Former PhD Students


Sabiha Majumder submitted her PhD thesis in July 2017 and defended her PhD thesis in Feb 2018. She was a student of the Integrated PhD program  of Department of Physics, IISc. She worked jointly with myself and Prof. Sriram Ramaswamy (Department of Physics, IISc) to investigate “Multiple stable states and abrupt transitions in ecosystems”. After her PhD, Sabiha joined as a postdoctoral fellow at Crowther Lab at ETH-Zurich.

Jaideep Joshi got his PhD from Centre for Ecological Sciences in 2017-18, working on “Spatial and coevolutionary dynamics of cooperation”. Before joining our lab, he graduated from IIT Bombay with a B.Tech in Electrical Engineering but his true interest lied in ecology, and field work. After his PhD, he joined as a postdoctoral researcher at Divecha Centre for Climate Change, IISc with prof Sukumar of CES.
