Lucknow Lab

In the Department of Zoology at University Lucknow, we have the teaching and research program on biological clocks providing expertise on physiological and behavioural analyses of clock in birds. The research in this relatively new area of Biology started with the joining of Prof. Vinod Kumar (now in University of Delhi) followed by Dr. Sangeeta Rani (2001) and Dr. Shalie Malik (2005). Dr. Sudhi Singh, presently working as faculty at Department of Zoology, NSN PG College is also the core member of this group. Our research area “Chronobiology of birds” has also been identified as the thrust area in UGC Special Assistance Program in both Phase I and II.

Arjita, Ph.D. Scholar, UGC-BSR Fellow


Research Interest: From the school days, I was very keen to study why every individual has different work preference or is active at different time of the day. My interest continued and I joined Ph.D. to work on the effects of different lifestyle on the behaviour and physiology of individuals.  The study parameters include daily profiling of physiological and behavioural aspects particularly chronotype, sleep wake pattern, blood pressure and temperature alongwith melatonin and cortisol (the two hormones that are involved in the regulation of sleep).


Ruchi, Ph.D. Scholar, UGC-BSR Fellow


Research Interest: The dramatic behavioural shift in a migrantory song bird species from predominantly day active to intensely night active has fascinated me. The environmental conditions prevailing at two times (spring and autumn) are different and therefore seem to influence the spring and autumn migrations. I am interested in studying the effect of photic and non-photic cues in regulating the spring and autumn migration.


Raj kumar, Ph.D. scholar, (RGNF)


Research Interest: My research interest is to study the light and food dependent effects on daily rhythms in Spotted Munia. Specifically I shall be studying the change in the phase relation between different markers of circadian rhythm such as activity, temperature and melatonin rhythm in response to differing duration of photoperiod and food availability.


Preeti Gupta, UGC-BSR Fellow


Research Interest: The external environmental cues interact with the internal circadian clock and help the birds to adapt their behavior and physiology to seasonal changes. I propose to work on the behavioral adaptations and brain functions in response to daily light environment, temperature cycle and food availability. I am interested in studying the seasonal changes in stress response under differing environmental conditions and its impact on physiology of migration/ molt and reproduction.


Pragya Verma, Ph.D scholar


Research Interest: My research work is based on studying the daily rhythms in school going young students. My studies include the chronotype analysis, sleep wake cycle, blood pressure and temperature patterns and measurement of melatonin and cortisol that are involved in the regulation of sleep.


Anupama Yadav, Ph.D scholar, UGC-BSR Fellow


Research Interest: My research focuses on the metabolic adaptations during different life history stages in migratory and non-migratory birds. To address my questions I would be studying the locomotor rhythm under different light, temperature and food conditions and will measure the oxygen demand and serum triglycerides levels, cholesterol, glucose etc. in blood.


Asma Naseem, Ph.D scholar, CSIR NET JRF


Research Interest: Photoreceptor cells that transmit light information to an avian brain are localized in retina, pineal gland and hypothalamus. These hypothalamic photoreceptors (deep brain photoreceptors, DBPs) are opsin based and have been implicated in the regulation of seasonal physiology. Focus of my research is identification and localization of different opsins in brain and retina of small passerine birds.


Anshu Dwivedi, DBT-Project Fellow


Research Interest: I am interested in studying the effect of light, food and temperature on daily and seasonal responses in migratory redheaded bunting (E. bruniceps). Also, my focus would be to find out, how these factors affect sleep pattern in migratory birds during different life history stages.


Khushboo, DBT Project fellow


Research Interest: Migratory birds on exposure to long days exhibit hyperphagia, gain in body mass and body fattening, appearance of migratory activity, and increase in gonadal size. My research question is to identify the physiological switch that triggers migratory activity in buntings (Emberiza sp.).

Vaibhav Vaish, JRF DBT Research Project


Research Interest: Climate change has a significant impact on bird populations around the world and is likely to add to the many existing pressures. Variation in climatic factors such as temperature, food availability, rainfall, humidity etc. may alter bird physiology including its reproductive strategies. Using different experimental strategies, I am interested to examine the effect of the changing environmental conditions on breeding strategy of songbirds.

Abhishek Kumar, CSIR-NET


Research Interest: The immune system is an integral part of physiology because it enhances the survival of the organism by decreasing the disease related mortality. The investment of an organism in immune system often differs during the seasons but how the changes in environmental conditions directly affect the immunity has not been explored much. Therefore, I am interested in studying the seasonal modulation in immune response in songbirds.
