Dr Marie Juanchich

Director of the DART Research Group


Kingston Business School
Kingston Hill campus
Kingston Upon Thames

+44 (0)20 8417 5252 Ext: 65252


Director of the Decision, Attitude, Risk and Thinking Research Group which gathered 25+ experts from different disciplines (e.g., psychology, sociology, geography).

Information about the DART Research group and our activities.

I have a MSc and a PhD in Experimental Psychology from the University of Toulouse (France).


Expert in how people communicate and perceive risk and uncertainty. I am for example working on how people perceive risks of drug side effects. I have also a good command related to individual differences that explain variations in reasoning and decision-making performances (e.g., thinking style, personality, cognitive reflection).

Research Interest(s)

Broadly, my research aims to gain a better understanding of the the factors affecting risk perception and decision making (e.g., how people understand probabilistic forecasts; how HR managers make personnel selection decisions). Additionally, I am interested in how individual differences account for variations in risk perception and decision making quality (e.g., investigating whether decision making styles predict decision making quality).

Topics I am interested in supervising:

  • Individual differences and decision-making quality (e.g., how personality predicts decision-making quality);
  • Discriminations at work and how to prevent them;
  • How to attract and retain volunteers in charitable organisations;
  • Behavioural change via email communication;
  • The role of acculturation for expats;
  • Strategies to solve inter-groups conflict;
  • Decision-making in social work and healt care professionals;
  • Engagement, job satisfaction, retention, and co.


It can also be useful to know that I have a preference for quantitative methods.



I am leading the module "Investigating a business issue" at PG level.

I am also the Course Director of the Undergraduate Diploma in Professional Practice for Business and Law UG students.
