  • Principal Investigator
      Gooley, Joshua J
      Associate Professor

      Harvard University, USA
      Dr. Gooley joined Duke-NUS Medical School in 2008 as an Assistant Professor in the Neuroscience and Behavioral Disorders Program. He is Principal Investigator of the Chronobiology and Sleep Laboratory, located in the SingHealth Investigational Medicine Unit at Singapore General Hospital. In 2005, he received his Ph.D. in Neurobiology from Harvard Medical School (HMS), where he studied neural pathways that mediate entrainment of circadian rhythms. During his postdoctoral fellowship at Brigham and Women’s Hospital (Boston, USA) and HMS, his research focused on effects of light on circadian rhythms and melatonin secretion. His current research program at Duke-NUS focuses on understanding the role of sleep and circadian rhythms in regulating human performance and physiology. (link to Dr. Gooley’s publications)

      The brain not only allows us to process sensory information and execute motor commands, but also allows us to think, analyze, and learn. The memories and experiences stored in the brain guide our actions in the future and facilitate problem-solving. I am interested in studying the neural mechanisms that underlie learning, memory, and creative thinking.

      Research Fellow

      PhD., Integrated Biology and Medicine
      Duke-NUS Medical School, Singapore
      The Chronobiology and Sleep Laboratory (CL) is also interested in the pupillary light responses, which are mediated by the same intrinsially photosensitive retinal ganglion cells (ipRGC) which mediate other non-visual responses to light like circadian rhythms and sleep/wake regulation. Rukmini worked on the development of a light exposure protocol for chromatic pupillometry useful for sreening of eye diseases, based on the differential light responses of rods, cones and ipRGC during her PhD at the CL. Prior to joining the CL as a Research fellow, she was with the Visual Neurosience laboratory at the Singapore Eye Research Institute and helped in the further development of chromatic pupillometry as a sreening tool for ocular diseases like glaucoma, diabetic retinopathy and others.

      My interests lie in the role of sleep in memory consolidation, both long and short term, alongside how the effects of alcohol and age can mediate these consolidation processes. I am also fascinated by the psychopharmacological effects of substances such as alcohol. At CSL I am looking to develop my research skills through experience with physiological and cognitive-behavioural methodology.

      Sleep is an intricate part of everyday life, and yet, despite its immense importance as a basic necessity to survival, we as human beings tend to forgo sleep in pursuit of more desirable exploits. As such, I have embarked upon this journey of joining CSL to better elucidate the underlying intricacies of sleep and circadian rhythms. I hope that my analytical and critical thinking skills would greatly benefit CSL.

      I have always been attracted to areas of science that can be applied to anyone's daily life, and the study of sleep is no exception. Through my stint at CSL, I wish to refine my research abilities, implement my existing knowledge and contribute to our understanding of sleep.

      I've been fascinated with sleep since my first lab attachment as an undergrad, where I studied the role of sleep and circadian rhythms in major depressive disorders. Since then, I developed a particular interest in the relationship between sleep and mood. As part of CSL, I look forward to investigating the effects of sleep on mood and how that interaction can affect day-to-day behavior such as cognition and learning.

      I have been fascinated with the fact that different people need different amounts of sleep while there is a standard amount of sleep hours for people at certain ages. Also, with my strong interest in social and interpersonal relationships, I am also passionate to learn more about sleep deprivation relating to social skills in school and work environments.

      Sleep is one of the few things we indulge in, that is considered a necessity, a pleasure and a vice all at once. At CSL, I want to explore this fascinating phenomenon and learn all I can about it.

      My interest lies in the deterioration of human performance after sleep deprivation, and the possibilities to mitigating such decrements. The thought that such knowledge could be applied to military personnel, or cabin crews, is quite exciting for me. I am also very drawn to the idea that sleep and metabolism are closely related; it is another avenue to channel effort into as Singapore moves towards a healthier society.

      In sleep, we dream, we recover, and we rise stronger tomorrow. I have an interest in examining how sleep affects daily living, learning, sociability, decision-making and food consumption. Returning as a full-time staff, I hope to carry on the laboratory's excellence in research.

      At CSL I’m interested in understanding more about the role of sleep and sleep deprivation on cognition and human performance. I hope to broaden my knowledge in designing and conducting neuro-cognitive experiments, collection and management of data, writing manuscripts and help with recruitment. By doing rigorous experiments, I hope that one fine day we will stumble upon great ideas to help people get better sleep and lead a healthy life.

      No one truly understands how the brain and mind works and mysteries are what keeps me going. In this vicious cycle of contemplating the workings of the human mind, the mind itself is attempting to figure itself out and that is pretty amazing. I aspire to one day make the most out of my time in a manner that benefits society.
