Dr Adhil Bhagwandin
Dr. Bhagwandin joined the Division of Clinical Anatomy and Biological Anthropology in November 2018. He obtained his PhD in Neuroscience from the University of the Witwatersrand, Johannesburg in 2011. He then completed a postdoctoral fellowship at the University of California, Los Angeles (UCLA) and Moscow State University. In 2014, Adhil was an awardee of a Research Career Award from the National Research Foundation (NRF) of South Africa and served the duration of this 5-year award as Senior researcher in the lab of Prof. Paul Manger at the University of the Witwatersrand, Johannesburg. Over the past couple of years, Adhil has taught neuroanatomy to medical students, health and rehabilitation students, and undergraduate science students. He has also co-supervised numerous postgraduate student training at the level of Hounors, Masters and PhD.
His research interests are vested in the understanding of comparative neuroanatomy, specifically the neuroanatomy of the sleep-wake system. Adhil typically employs the techniques of electrophysiology, immunohistochemistry, and stereology in his line of research. Sleep is a behaviour common to all organisms, yet its function remains a mystery. By understanding how sleep behaviour and the neuroanatomy controlling this behaviour varies across different vertebrates, we can then start to understand the evolution of this common behaviour and possibly begin to infer its function.
During his post graduate training, and apart from his own research, Adhil worked on understanding the neuroanatomy of the brains of various mammals (porcupine, mole rats, cane rats, megabats, microbats, hyraxes, giraffe, etc.). During his postdoctoral fellowships, Adhil had the fortune of working with the semi-aquatic Northern fur seal, whose sleep phenomenology is quite unique in the sense that it shows both bilateral brain activity as well as unihemispheric brain activity during sleep. Adhil also had the pleasure of working with wild free-roaming elephants in Botswana, and wild free-roaming oryx in Saudi Arabia. His involvement with the elephant and oryx research has yielded novel ideas regarding environmental parameters that influence the onset and offset of sleep in mammals.
Adhil wishes to continue his work in comparative sleep research by investigating and understanding the glymphatic system of the vertebrate brain and its relationship to sleep.
