Abhilash Lakshman, Ph.D.

  • Postdoctoral Research Associate, Shafer Lab, Neuroscience Initiative

Abhilash graduated from the University of Calcutta with a B.Sc. (Hons.) in Zoology and minors in Chemistry and Botany.  During his undergraduate studies he worked on the evolution of adult emergence chronotypes in Drosophila melanogaster populations in Vijay Kumar Sharma’s (VKS) chronobiology lab at the Jawaharlal Nehru Center for Advanced Scientific Research (JNCASR), Bangalore.  Subsequently, he joined JNCASR for an Integrated Ph.D. program in the fall of 2012.  During his MS course at JNCASR, he studied and carried out research in a wide variety of organismal biology disciplines ranging from population genetics, animal behavior, population dynamics and behavioural neurogenetics to chronobiology.  He completed his MS thesis in 2015 with VKS, where he examined the circadian clock properties of morning and evening chronotypes in Drosophila.  He continued in the same lab for his Ph.D. and studied the inter-relationship between circadian organisation, mechanisms of entrainment and timing of behavior, and submitted his thesis in January 2020.

In order to pursue his interests in classical chronobiology and understand the physiological underpinnings of circadian entrainment, he joined Orie Shafer’s lab at the ASRC in March 2020 as a Research Associate.

Research Interests

Understanding the evolution and functional significance of circadian clocks; genetic, neuronal and physiological regulation of timing of behavior; and the role of circadian clocks in shaping inter-species relationships.
