Biography

--------
I hold a PhD from University of Cambridge in cognitive neuroscience of human decision making. My background is in psychology (B.Sc.) and economic psychology (M.Sc). During my studies at Cambridge we identified various brain responses characterizing decision making under risk. Specifically, a signal at an area called right DLPFC changed according to differences in individual’s risk aversion (Journal of Neuroscience, 2009). Using brain signals we were able to predict individual choices on a trial-by-trial basis. In other studies (PNAS, 2009; JofN, 2010) we identified how the brain distorts value and probabilities. Following Cambridge I moved to Baylor College of Medicine and then to Virginia Tech to work with Brooks King-Casas at the Laboratory for Interpersonal Decision Making, where I explored neural correlates of social decision making in normal populations, the effects of pharmacology on social learning and learning parameters as influenced by psychopathology and addiction.
Research Interests
*********Update*: Please go tohttps://deonlabblog.wordpress.com/ for my lab webpage

--------

Broadly, I am interested in exploring the mechanisms that describe and/or affect behavioral and neuronal responses while humans make decisions, especially in social settings. This is of course a very general question that encompasses very diverse topics such as:

- Individual decision making (deciding on the absence of social information. Risk is one of my main interests)

- Social decision making and strategic interactions (deciding while other agents are socially visible and present: allocation of resources; competition and cooperation, learning)

- Organizational Neuroscience (organizations are the ecology of the modern human; I am interested in how the structure of organizations influences biology and vice versa)

Coming to Singapore and NBS I found an environment with outstanding expertise in Cultural Psychology; my aim is to integrate this expertise with my interests.


Methods

Special emphasis should be given to the methods. I try to integrate different approaches aiming in exploring mechanisms while moving away from simple descriptive approaches, which while interesting are not anymore adequate to help us understand and predict behavior. To that aim I use:

- Behavioral experiments and game-theoretic inspired approaches modeling social interactions and decision making.
- Psychophysics
- Computational Modeling
- Biological and genetic measures (eye-tracking, skin conductance etc)
- Functional Magnetic Resonance Imaging to encode brain responses
