Dragan Rangelov

Dr Dragan Rangelov serves as an Honorary Senior Research Fellow at the Queensland Brain Institute, University of Queensland. He earned a degree in Psychology, equivalent to BSc Honours, from the University of Belgrade, Serbia, followed by an MSc in Neuro-Cognitive Psychology and a PhD in Systemic Neurosciences from Ludwig-Maximilians-Universität München, Germany. His academic career includes postdoctoral research at LMU Munich's Department of Psychology. In 2016, he joined the Mattingley Lab at the Queensland Brain Institute as a postdoctoral researcher. From April 2023 to October 2024, he held the position of Research Fellow in Neuroeconomics at the same institute. His work at UQ has involved collaborations on projects examining perceptual decision-making and neural processes, contributing datasets to UQ eSpace, including those on audiovisual prediction error (2024), BayEst-01 (2024), white matter microstructure and visual working memory (2024), posterior beliefs in visual information foraging (2025), and reproducibility demonstrations (2025).

Rangelov's research focuses on the neural and psychological mechanisms of human sensory perception, decision-making, and memory. He investigates how the brain integrates sensory information for perceptual decisions, with emphasis on visual attention, working memory precision, evidence accumulation, metacognition, sensory adaptation, and attentional dynamics. Employing psychophysics, EEG, and fMRI, his studies reveal patterns of neural activity linked to sensory stimuli and decision processes. Key publications include 'Integrated Perceptual Decisions Rely on Parallel Evidence Accumulation' (The Journal of Neuroscience, 2024, with Julia Fellrath and Jason B. Mattingley); 'Intrinsic Functional Networks for Distinct Sources of Error in Visual Working Memory' (Cerebral Cortex, 2024, with Xuqian Li et al.); 'Distinct Early and Late Neural Mechanisms Regulate Feature-Specific Sensory Adaptation in the Human Visual System' (Proceedings of the National Academy of Sciences, 2023, with Reuben Rideaux et al.); 'On Second Thoughts: Changes of Mind in Decision-Making' (Trends in Cognitive Sciences, 2022, with Caleb Stone and Jason B. Mattingley); 'Stimulus Reliability Automatically Biases Temporal Integration of Discrete Perceptual Targets in the Human Brain' (The Journal of Neuroscience, 2021); and 'Evidence Accumulation During Perceptual Decision-Making is Sensitive to the Dynamics of Attentional Selection' (NeuroImage, 2020). These contributions have advanced insights into adaptive behaviour, cognitive control, and neural plasticity in perceptual and economic decision contexts.
