Research Interest: Food availability can act as dominant cue in opportunistic breeding species, and hence determines the reproductive success. Using opportunistic breeding songbird species, the zebra finches, my research focuses on deciphering the food-induced pathway involved in the regulation of affiliation behaviour and reproduction in zebra finches. Our aim is to first monitor affiliation behaviours such as the mate-choice, pair bonding, copulation and associated behaviours by audio and video recordings, and investigate the molecular candidates that possibly are involved at the mechanistic levels in controlling the reproduction.

Research Interest: Using different experimental strategies, our lab has been carrying out studies aimed to understand the photoperiodic regulation of seasonal life-history states (LHSs) in Palaeacrtic-Indian migrants. My research is going to focus on the molecular candidates that possibly mediate the photoperiod-induced effects on seasonal LHSs. Particularly, I am interested to examine changes that occur with the onset and termination of a LHS. Because, the changes may involve different DNA modifying enzymes, we are also interested to examine epigenetic modifications with alterations in the LHSs.

Research Interest: My research interest lies in characterizing at different levels the circadian rhythms in a moth (Spodoptera litura), in collaboration with the Prof. Rakesh Kumar Seth’s lab. We would like to focus on the effects of different light regimes on the expression of clock genes in the reproductive tissues of Spodoptera litura. Because this moth is a pest, we are interested in examining whether gamma radiations effects, envisaged as a potential pest control strategy, impair the reproductive clock of Spodoptera litura.

Research interest: Birds are inevitably influenced by their environment. Both the food type and its availability affect the development and physiology of birds. Our aim is to understand whether food-effects on reproduction and metabolism are mediated by its effect on the endogenous circadian clocks. For this, we are using zebra finches, an opportunistic breeder, as experimental model for these studies.

Sayantan Sur, Ph.D. Scholar, CSIR-NET JRF

Email: sayantansur008@gmail.com

Research Interest: My aim is to understand the effects of both Photic and non-photic cues on development of migration and its associated changes in metabolism, immune function, and neuroendocrinology of birds, using black headed and red headed buntings as the experimental systems. In particular, I intend to examine at gene expression levels, the changes in brain and immune functions when birds are exposed to abrupt light/ temperature conditions, in parallel with changes in physiology, behaviour and cognitive phenotypes.

Nisha Singh, PhD Scholar, CSIR-NET JRF

Research Interest: My research interest lies in studying the effects of life style on daily activities in humans. People with different lifestyle may have differences in the way their interal timing is organized for different functions during the day. The major focus of my research is going to be studying differences in sleep patterns and associated performaces between working and non-working women.

Indu Malik, PhD Scholar, UGC-NET JRF

Research Interest: Recent research shows that microbes play an important role in regulating animal’s physiology. We are interested in investigating whethere there is seasonal pattern in the gut microbiome diversity, and if yes, whether this has influence of seasonal biology of non-migratory and migratory birds.

Research Interest: Corvids have emerged as an important avian model in deciphering higher cognitive abilities and their causal brain mechanisms. The focal point of my research is to study the light environment dependent changes in mood and cognition and effects of aberrant light conditions on cognitive behaviour of Indian House Crow (Corvus splendens). My aim is to understand how dim light at night affects the neural basis of complex cognition and underlying physiological mechanisms by means of simple learning to complex problem-solving tasks and behavioural observations.
