Principal Investigator

Gooley, Joshua J
Gooley, Joshua J Associate Professor joshua.gooley@duke-nus.edu.sg PhD 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)

Of all the organs in the human body, the brain is by far the least understood; yet it is the black box that is responsible for human consciousness. Given that humans spend a substantial amount of time sleeping, the study of sleep is vital to the unravelling of the mystery that is the brain. I want to better understand the biological necessity of sleep (in particular its effect on cognitive processing), the manifestation of individual differences in sleep (e.g. sleep patterns, sleep deprivation thresholds, sleep disorders), and how to leverage the full therapeutic properties of sleep to enhance individual performance and well-being.

A good night's sleep isn't a luxury, it's a necessity. Yet many of us (myself included) often put sleep on the back burner in the struggle to balance work and family demands. What intrigues me is why we continue to deprive ourselves of sleep when we are fully aware of the consequences. As a student in CSL, I want to understand what pushes us to sleep at the timings we do, how that decision affects us, and how we can help others to recognize the importance of adequate sleep.

I am interested in analysing large datasets to gleam for useful information. Here, I am using information collected by the Institute for Applied Learning Sciences and Educational Technology (ALSET) to study how university students' activity patterns relate to their sleep and cognitive outcomes. Oh and I play games in my free time.

The brain is a fascinating organ and there is so much unknown about it. Sleep is such an important behavior for wellness yet there are many obstacles to achieving adequate quality and quantity. Combining my interest in neuroscience and health, I would like to investigate how sleep and wellness are closely related and how sleep could be a prophylactic and/or therapeutic medicine, hopefully contributing to the sleep health awareness.

Kastoori D/O Kalaivanan Research Fellow kastoori@duke-nus.edu.sg PhD., Linguistics
Nanyang Technological University, Singapore

Kastoori graduated with a PhD in Linguistics from Nanyang Technological University in 2020. She is currently working at the Chronobiology and Sleep Lab as a postdoctoral research fellow. Kastoori's research previously investigated how cognitive and demographic factors affect speech processing across the lifespan. Her current research looks at how sleep deprivation affects learning and she is also exploring new methods of research and statistical analyses at the CSL lab. Her hobbies include cooking, traveling (pre-COVID days) and spending time with family.

Sleep is a precious commodity for the living yet there is so much that we have yet to understand about it. Given that I have written my previous thesis in Sleep Science (specifically on a novel clinical treatment for Obstructive Sleep Apnea), seeing actual patients opened up my eyes and I decided to pivot away from neuroscience to sleep science, making this my main area of interest. Hence, I want to investigate how sleep impacts our daily lives from mood to mental health to learning through research under CSL and Joshua Gooley.

Who amongst us hasn’t forgone some minutes (or hours) of sleep to spend more time with our favourite people or activities, only to inevitably face the sleep-debt consequences? Sleep is a key physiological need that has an inexplicable link to our behaviours, thoughts and feelings. I am curious about the relationship between sleep and cognitive functions like attention and memory, as well as sleep’s impact on mental health in both the short- and long-term. I hope to learn more so I can improve my own sleep cycle along the way.
Tan Yi Hong
Tan Yi Hong Research Assistant tyh02@nus.edu.sg B. Soc. Sci. (Hons) Psychology
Nanyang Technological University, Singapore

I am a Research Assistant at the SIA-NUS Corp Lab, and am currently working on improving sleep quality and passenger comfort within the aviation industry. My responsibilities include data collection, processing and analysis. Prior to joining the lab, I delved into gaming psychology and examined the motivation of gacha gamers for my undergraduate degree.

Outside of research, I enjoy travelling, gaming, and watching films and shows. Occasionally, I would create fan-contents related to those games or shows.
Cindy Leow
Cindy Leow Research Assistant cindyl@nus.edu.sg B. Soc. Sci. (Hons) Psychology
National University of Singapore, Singapore

As a Research Assistant at the SIA-NUS Corp Lab, my responsibilities include running experimental procedures, data processing and analysis. I graduated with a degree in Psychology from NUS. Prior to joining the lab, I had a brief stint in the Special Education sector where I worked with children with autism. I am interested in finding out how to improve sleep among educators and children with autism in the Special Education sector.

Outside of work, I enjoy spending time with loved ones, listening to music and occasionally gaming. If I am not gaming, I will be found sleeping or enjoying a good read somewhere.

Nanyang Technological University, Singapore

I am a Research Assistant at the SIA-NUS Corp Lab. I graduated with a degree in Biological Sciences from NTU. My experiences include researching on dreaming states in sleep disorders, which has piqued my keen interest in sleep research. Since then, it has become the focal point of my academic journey and I am dedicated to understanding its intricate mechanisms and exploring its implications for human health and performance. Outside of research, I am an ardent traveler who finds inspiration and enrichment in exploring diverse cultures, landscapes, and experiences. Traveling not only allows me to unwind and recharge but also provides a unique perspective on the importance of sleep across different cultures and time zones.
