Research

My research integrates the cognitive processes of learning and decision making mechanisms in humans. Projects that are currently ongoing include behavioral and neural correlates of statistical learning, perceptual and value-based decision making. A wide range of experimental and analytic techniques such as psychophysics, eye tracking, brain imaging methodologies (EEG, fMRI) and computational modelling (Reinforcement learning, Bayesian approaches) are used. With machine learning approaches applied to structural MRI images, I am working on early detection of Alzeimhers’ disease.

** NEW ** Postdoctoral openings under Cognitive Science Research Initiative ***

The PI is interested in supporting applications for postdoctoral fellowships for the year 2017-18 at the interface of cognitive science and computational modelling in the following projects

1) Early detection of Alzheimers disease using machine learning approaches: The candidate should have prior experience of Functional or structural MRI analysis and good computational and programming skills, willingness to learn and apply machine learning methods

2) Computational modelling of emotion and decision making: The candidate should have prior experience in psychology and neuroscience of decision making and be comfortable with drift diffusion models, Bayesian models, and machine learning approaches in modelling emotion recognition through empirical cognitive psychological methods

3) Behavioural analysis of road safety behaviour: The candidate should have very good skills of Big data analytics together with solid background in experimental psychology.

Broad Research Topics

  • Computational approaches in Brain Imaging

This topic covers Cognitive Neuroscience investigations through functional brain imaging (EEG & fMRI) focussed on attention, perception, mental imagery, action, discrete and continuous movements, learning and decision making. Modalities include visual, auditory and motor. Particular focus will be on model based fMRI e.g. reinforcement learning, meta analysis approaches e.g. activation likelihood estimation, functional connectivity approaches, Resting state and default mode networks, Bayesian modelling, multivariate pattern analysis using machine learning algorithms.

  • Integrated approaches in Learning

This broad topic covers multifaceted investigation of learning phenomenon such as visuomotor sequence learning, associative learning, habit formation, reinforcement learning, category learning, statistical learning, information theory, language & artificial grammar learning, rote learning, observational learning, and learning dynamics in games. Interfaces with other related areas such as effect of learning on attention, memory, decision making, and music and emotional modulation are studied.

  • Reward, Decision making, Game theory & Neuroeconomics

This topic focuses on classical and instrumental conditioning approaches for reinforcement learning. Particular emphasis is on computational modelling of reinforcement learning integrated with decision making. Empirical work will focus on Game theory and interactive learning in Gaming situations and social decision making.

  • Consumer behaviour & Neuromarketing

This topic focuses on comparative studies of consumers in different economic markets and cultural backgrounds in terms of brand loyalty, distributor owned brands, economic modelling of purchase behaviour, prediction of consumer decisions, dynamics underlying consumer decision making particularly in single vs multi attribute/conjoint decisions. Techniques employed include eye tracking, emotion prediction through facial recognition, data mining text analysis for keywords, mouse tracking, approach and avoidance behaviour, change of mind in decision making. A second focus of this topic is on brain imaging studies for neuromarketing focussed.
