George Christopoulos (Principal Investigator)

I hold a Ph.D. in Decision Neuroscience from the University of Cambridge (with Wolfram Schultz) and did my postdoctoral research at Virginia Tech and Baylor College of Medicine (Brooks King-Casas). I am Associate Professor at Nanyang Business School, NTU, Singapore), co-Director of the Culture Science Innovations,  Executive Committee director for the Methods/ Education section for the Academy of Management Org. Neuroscience Group (NEU), member of the Advisory Council for the Academy of Neuroscience for Architecture and collaborator for the UPenn Center for NeuroAesthetics.

In my lab we use advanced neurobehavioral methods to examine the following questions:

  • Environmental (Urban) Neuroscience: we focus on the effect of indoor and outdoor spaces, and their architectural characteristics on human performance, health and happiness. A recent grant examines the effect of soundscaping and sounds on human cognition
  • Human learning and decision making (risk and trust), with a focus on cognitive flexibility and computerised training of working adults
  • Beauty and aesthetics: deeper beliefs about beauty and how they affect consumption of cosmetics; and how culture and cultural symbols (statues, images, buildings) affect emotions as well aesthetic and other judgments;
  • Methods: besides traditional methods,  we employ behavioural methods derived from psychology; computational methods stemming from game theory, learning theory and microeconomics; and biological measurements such as human neuroimaging using functional Magnetic Resonance Imaging (fMRI) and EEG; and we are also interested in Virtual Reality and Wearables.

Besides typical grants (over $2m) we have also collaborated and supported by various private companies and multinationals (such as cosmetics companies) to understand how consumers choose and use cosmetics and other products, using implicit and explicit methods .

Our research has been published in leading multidisciplinary and specialized journals (Journal of Neuroscience, PNAS, Building and Environment, Energy Research & Social Science, Journal of Experimental Social psychology, Journal of Environmental Psychology, Journal of Business Ethics etc.). 

Research (PostDoctoral) Fellows

Adam Roberts (Ph.D. Sheffield; Previous PostDoc Oxford): Psychological and neurobiological aspects associated with the built environment

Alvin Lee (Ph.D. University of Western Australia)

I am a cognitive neuroscientist with a PhD from the School of Psychological Science, University of Western Australia, under the joint supervision of Allison Fox (Neurocognitive Development Unit) and Lies Notebaert (Centre for the Advancement of Research on Emotion). My PhD research aimed at examining the neurobiological underpinnings of obsessive-compulsive symptoms, as well as other internalising symptoms, in children and adults. Currently, I am a research fellow at Nanyang Technological University working on a project regarding the psychological effects of soundscape. My research interests include biological psychology, cognitive psychology, developmental psychology, and human factors.

Shengchuang Feng (Ph.D. Virginia Tech)

I am currently a postdoctoral research fellow at the Centre for Lifelong Learning and Individualised Cognition (CLIC) of Nanyang Technological University. I received my doctoral degree in psychology at Virginia Tech, and was a postdoctoral associate at the Fralin Biomedical Research Institute of Virginia Tech. My research interests include social cognition, reward-guided learning/decision making and related disruptions in mental disorders such as depression, addiction, and anxiety. I use computational models, self-report measures, and functional magnetic resonance imaging to understand both behavioural and neural mechanisms of social/nonsocial cognition in healthy people as well as in mental illnesses.

Nadhilla Velda Melia (Ph.D. Singapore Management University)

I am a postdoctoral research fellow at the Centre for Lifelong Learning and Individualised Cognition (CLIC) at NTU. I received my PhD in Psychology from Singapore Management University. My research interests lie in social decision making, emotions and group cooperation. Specifically, I am interested in how others’ emotion expressions affect an individual’s decision making and cooperative behaviours. At CLIC, I will be investigating the relationships between sociocognitive variables, such as tolerance of uncertainty and perceived social support, and cognitive flexibility.

PhD Students

Kim Loong (Environmental Decisions)

Please see here for my work. I am exploring the process and factors involved in decision-making with regards to energy-usage, efficiency and environmentally responsible behaviour. Prior to joining the DEON Lab, I completed a bachelor’s in Psychology and a Masters in Neuroscience at the University of Queensland.

SAM Yoke Loo, Emma (Science of Learning)

My research interests include organisational behaviours, career development, neuromarketing, behavioural & experimental designs, quantitative multivariate analysis, and psychometrics. For my thesis, I will be developing a nomological network of Cognitive Flexibility (CF) to explain the role and impact of CF on career decision making and outcomes.

Irene Melani (Culture and Cognition)

I am a visiting Ph.D. Candidate from the University of Michigan, USA. My research interests lie broadly at the intersections of culture, cognition, and intra/intergroup processes. Specifically, I am interested in the cognitive mechanisms underlying cultural variations and the ways individuals organize themselves within groups. My research seeks the use of interdisciplinary methods, with a focus on neuroscience and behavioral economic games approaches.

Research Assistants

Lee Li Ling

After graduation (in psychology) from James Cook University, Singapore, I joined a lab and researched on topics focusing on the effect of socio-cultural factors on appetite and eating behaviour for a few years. My research interest is in social and cultural psychology, specifically in understand how socio-cultural factors affects different aspect of human mental and psychology behaviours.

Yap Hui Shan

After my graduation from UB-SIM (in Psychology), I worked with a multi-disciplinary research group from NTU examining how different psychological and social factors can affect an individual’s functioning in (and their perception of) different spaces. My current research interest includes exploring topics related to social psychology, neuropsychology as well as learn more about different analysis methods.

Elliot Chan

Having graduated from the University of Buffalo undergraduate program in Psychology, I have been involved in various projects for the Lab, such as the creation of the Asian Face database. I am also an independent filmmaker, magician, martial artist, techno-wizard, and soon-to-be cyborg ninja on wheels. My special abilities include drinking copious amounts of caffeine with no ill effects, and cooking “3-minute instant noodles” in 2 minutes and 47 seconds.

Tan Yan Fen

I graduated with a Bachelor of Science from Nanyang Technological University. My research interest is in Psychology, Neuroscience and Earth Science. 
Chan Yuan Ni

After graduating with a Bachelor of Science from Monash University, Australia, I completed my fourth year studies in Psychology at Deakin University, Australia. My research interests are in the field of social psychology as well as neuropsychology.

Pei Jia Ying

I am a graduate of National University of Singapore with a Bachelor of Social Sciences in Psychology. My research interests lie primarily in examining the environmental and social factors that affect the cognitive and behavioural development of children and adolescents.
