Statistical Learning and Bayesian Inference
BiographyI am a computer science Ph.D. student at EPFL working under the supervision of Wulfram Gerstner. I work on computational models of learning and decision-making in the brain with a focus on (i) mathematical definitions of surprise and novelty, (ii) their contributions to human exploratory and adaptive behavior, and (iii) their manifestation in physiological measurements. I use Bayesian inference, reinforcement learning, and information theory to develop computational models which I test against behavioral and physiological data (EEG, MEG, fMRI, and single neuron recordings).
Prior to joining EPFL, I received my B.Sc. in Electrical Engineering from the Sharif University of Technology, Tehran. During the last two years of my study, I worked on several research projects and completed my B.Sc. thesis under the supervision of Hamid Aghajan. My projects were mainly on (i) EEG-based decoding of surprise and (ii) fMRI-based classification of visual and auditory stimuli. My thesis won the 2nd best thesis award in the annual departmental distinguished thesis competition.
