Decision Making Research

"It is our choices, Harry, that show what we truely are, far more than our abilities." - J.K.Rowling, "Harry Poer and the Chamber of Secrets" 

The goal of our group is to develop a mechanistic understanding of the neural computations underpinning the decision making process across a broad range of domains such as perceptual, economic and social choice.  We approach this question by combining computational modelling with experimental economics, psychophysics and brain imaging methods.

I studied physics at the University of Milano-Bicocca, where I obtained a MSc with a thesis on estimating the plasma density in thermonuclear fusion reactors. Then, as a PhD student with Dominik Bach at the University of Zurich, I applied computational methods to study the behavioural and neural bases of fear and anxiety. In Benedetto De Martino’s lab, I am investigating how uncertainty drives learning and concept generalisation, and whether this knowledge could help building more flexible machines.

My background is in engineering, brain imaging and neuroscience. I am a Biotech Engineer and MSc in Engineering from the Pontificia Universidad Católica de Chile. I also have a MSc in Neuroscience from King’s College London. I am currently doing my PhD in the BdM lab and am interested in the role that uncertainty has in decision and learning processes. Particularly in how action and values are integrated into the construction of confidence

I am a Biotech Engineer from the Pontificia Universidad Católica de Chile, where I also got my MSc in Engineering. My thesis focused on developing machine learning classifiers based on Brain MRI to better understand multiple sclerosis. I'm currently investigating the difference between perceptual and value-based decisions.

I have studied Psychology at Newcastle University and am now a masters student on the Cognitive Neuroscience MSc programme at UCL. I am interested in how our memories contribute to the decisions that we make and will work with eye tracking. I am particularly interested in the link between value judgements and memory, and the level of confidence that we have in our decisions.

I am a Genetics graduate from University of York, where I focused on the overlap between molecular biology and neuroscience. I put great emphasis on both multidisciplinarity and research in itself, and I was eager to extrapolate my biological understanding of the brain to a cognitive perspective. This led to my academic journey on a MRes in Brain Sciences at UCL. I currently investigate the phenomena of confidence-leak in humans where I employ diverse psychophysical and neurobiological methods to better understand the roots of overconfidence, and how overconfidence may bias our everyday decisions.

My work aims to understand what the benefits (and costs) are of being aware of one's confidence in a given decision.

I study how people gather information that is used to guide decisions and how this shapes our sense of confidence
