  • 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)

      How much and how well we sleep greatly influence our cognitive and emotional processing on a day-to-day basis. As a graduate student at Chronobiology and Sleep Laboratory, I am interested in the role of sleep in mental health and wellbeing. Additionally, I am interested in using physiological recordings as objective measures of human emotional processing.

      MSc Chemistry
      National University of Singapore, Singapore
      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.

      Rukmini Dhara
      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.

      For something that takes up more than one-third of our lives, what we really know about sleep is arguably not a lot. Nonetheless, its effects on daily human performance or even clinical populations are salient and extremely significant. I am thus interested in furthering our understanding of sleep behavior, and how it can be integrated into interventions to improve one’s physical and mental health.

      Sleep is often neglected in pursuit of contemporary demands like work, good grades, and so on. However, having sufficient, good quality sleep is critical not just for higher productivity, but our mental wellbeing as well. I’m motivated to explore approaches to improve sleep behaviour, in hopes that our research can inform policy changes on the broader scope too.

      Sleep is increasingly being seen as the third pillar of health alongside exercise and a healthy diet. Lack of sleep presents a major health issue in modern society, detrimentally impacting both our brains and our bodies. At CSL, I'm interested in probing the effects of sleep deprivation on brain function, particularly in the processes of attention, memory and learning.

      I am interested to better understand physiological and environmental variables that can facilitate improved cognitive processing and learning. Sleep (the adequacy of it) is an important factor. It has been found a necessary condition for optimal neuropsychological functioning. In my earlier research life at the Neurolinguistics and Cognitive Science Lab (NTU), I examined the impact of music experience on language learning.

      Sleep, although usually taken for granted, is absolutely essential to ensure proper function of our brain and body, such as cognitive processing and glucose metabolism. Thus, with this opportunity I hope to leverage on my previous research experience to explore and elucidate the role of sleep in learning and memory.

      My research interests are in improving learning and policy outcomes through information processing models of memory, and higher cognitive processes. In the lab, I seek to understand how sleep impacts these processes and the mechanisms of which they do so. Prior to joining ALSET, I worked in the Synergy Lab, researching on the attitudes and behaviours towards organ donation policies.
