Dr Tsvetomira Dumbalska
BA Brown, MSc Oxf, DPhil Oxf
Stipendiary Lecturer
I completed my DPhil in Experimental Psychology just around the corner in Pembroke College. My background is an interdisciplinary blend of the cognitive sciences, with an undergraduate degree in Economics from Brown University and research bridging psychology and computer science. My teaching and research focuses on human learning, decision making and motivation.
At Brasenose, I teach undergraduate students across the Experimental Psychology and Psychology, Philosophy and Linguistics courses. I have led tutorials across Introduction to Psychology, Statistics, Social, Cognitive, Developmental, and Individual Differences and Clinicial Psychology, as well as programming classes and advance options in Economics and Psychology.
My research investigates how the structure and order of information affects how humans and artificial neural networks learn about the world and make decisions. My work combines big data from experiments in gamified environments and computational modelling to shed light on the information processing mechanisms in humans and artificial neural networks. I have published research articles on how contextual information affects our perceptual and value-based choices, and how humans and artificial agents learn about the structure of the world and what is valuable. I am actively involved in the open science movement and initiatives to increase the transparency and reproducibility of research results.
