My research is focused on the study of human visual system. I use a combination of human psychophysics and computational modelling techniques to uncover the functional characteristics of the neuronal mechanisms of visual functions including motion perception, spatial vision, and stereovision.

RLV is supported by the fellowship BES-2015-074077 from Ministerio de Economía y Competitividad (Spain). Having completed a Bachelor in Psychology and a Master’s degree about statistical and mathematical methods applied to behavioral research, he is now doing his PhD in the field of visual psychophysics; making advances in order to functionally characterize the inhibitory mechanisms found in motion perception. Particularly, he is studying the inhibition underlying the interaction between motion sensors tuned to coarse and fine scales. RLV is therefore mainly interested in 2D motion perception, but he has also ventured into the areas of 3D motion perception and spatial vision.

Sandra Arranz-Paraíso (2017-)
Having completed a Bachelor in Psychology (Cognitive Science Track) granted with Grade Extraordinary Prize and a Master’s degree about statistical and mathematical methods applied to behavioural research (Master thesis: Optimization of the non-parametric Robbins-Monro procedure for threshold estimation and its comparison with Bayesian adaptive procedures). She is now doing her PhD in the field of visual psychophysics; making advances in order to characterize the inhibitory mechanisms underlying motion perception. SAP is therefore mainly interested in 2D motion perception, but she is also interested in haptic perception in virtual environments. Currently she is collaborating with the Prof. Manuel Ferre Pérez at the Automation and Robotics center of CSIC and Polytechnic University of Madrid (ETSI II).
SAP is supported by the fellowship FPU16/02683 from Ministerio de Educación (Spain).
