Biographical Profile
Justin DAUWELS is an Associate Professor with School of Electrical & Electronic Engineering at Nanyang Technological University (NTU). He is also the Deputy Director of ST Engineering-NTU Corporate Lab and the Director of Neuroengineering Program at the School of EEE. His research interests are in Bayesian statistics, iterative signal processing, machine learning and computational neuroscience. Prior  to  joining  NTU,  Justin  was  a  research  scientist  during  2008-2010  in  the Stochastic Systems Group (SSG) at the Massachusetts Institute of Technology, led by Prof. Alan Willsky. He received postdoctoral training during 2006-2007 under the guidance of Prof. Shun-ichi Amari and Prof. Andrzej Cichocki at the RIKEN Brain Science Institute in Wako-shi, Japan. He obtained  his  PhD  degree  in  electrical  engineering  from  the  Swiss  Polytechnical  Institute  of Technology (ETH) in Zurich in December 2005. The research of his lab has been featured by BBC Click/World News, Singapore Straits Times, national TV, and various other media. Outcomes include  real-time  algorithms  for  large-scale  urban  traffic  prediction;  real-time  algorithms  for analysing human social behaviour; real-time noise-resilient algorithms for phase imaging; novel data analytics for biomedical signals; tools for large-scale modelling of extreme events.

Research Interest in the Neuroscience of Learning and Education

Recent years have witnessed a paradigm shift in teaching methods to move beyond traditional strategies to improve learning and engagement. One such example is team based learning (TBL) that has been  shown  to work well especially in the context of  medical education.  However, instructors are often faced with the difficulty of assessing the team effectiveness and students’ engagement that is shaped through social interactions. We propose a multipronged approach to studying team based learning by combining social physics, social signal processing and social neuroscience methods.

a) Social physics: To quantify information flow between students of the entire class or even department, in order to predict outcomes of team-based learning from digital bread crumbs such as learning platforms, forums etc.

b) Social indicators: To quantify the nature of social interactions through real-time analysis of social behavior as markers to predict outcomes of team-based learning. Example: social indicators such as interest, confusion, dominance, frustration  can be automatically analyzed to provide feedback to improve learning.

c) Social neuroscience: To investigate the underlying brain process to look for neural markers to predict outcomes of team-based learning (e.g., synchrony between brain signals from students). Our preliminary results in a gaming context involving EEG recordings during social interactions show that higher scores are proportional to higher connectivity (EEG signal synchrony) among the team members.
