Karl Gegenfurtner studied Psychology at Regensburg University. Subsequently he obtained a Ph.D. degree from New York University, where he also spent his first PostDoc. In 1993 he moved to the Max-Planck-Institute for biological cybernetics in Tübingen, where he obtained his Habilitation in 1998 and a Heisenberg-Fellowship in the same year. In 2000 he moved to the University of Magdeburg and in 2001 to Giessen University, where he since then holds a full professorship for Psychology. The emphasis of Karl Gegenfurtner’s research is on information processing in the visual system. Specifically, he is concerned with the relationship between low level sensory processes, higher level visual cognition, and sensorimotor integration. Karl Gegenfurtner is the head of the DFG Collaborative Research Center TRR 135 on the “Cardinal mechanisms of perception”. He was elected into the National Academy of Science Leopoldina in 2015, received the Wilhelm-Wundt medal of the German Psychological Association (DGPS) in 2016 and an ERC Advanced Grant on color vision in 2020.

My research focuses on (i) the control of voluntary eye movements such as saccades and smooth pursuit eye movements and (ii) their interactions, and (iii) the effect of eye movements on our visual perception. In this context I try to find out what and when visual information triggers eye movements and what kind of visuo-motor strategy we use to find the information we need or when unexpected events occur. I am also interested in the perception of complex stimuli such as abstract paintings.

My research interests include virtual reality, colour constancy, CNNs, computational colour and HDR applications. I am working to understand the way we perceive the world, especially colour. I believe virtual reality is the perfect tool for studying that. We cannot change the physics of our environment, but we can do that using game engines.

I obtained my PhD in cognitive/experimental psychology at the University of Queensland, Australia. Currently I am working on the mechanisms underpinning categorical color perception using a variety of different techniques such as behavioural, EEG, fMRI, and virtual reality.

I am interested in human vision, in particular color vision. We use psychophysics, computational modeling, and natural scene statistics to understand the principles that govern the representation and the processing of color and form.

My research centers on eye movements and visual perception. I focus on the interactions of saccadic and pursuit eye movements, and how our eye movements are controlled across different stimulus complexities ranging from white disks on gray backgrounds to naturalistic videos. I am also interested in how we are able to have a constant and vivid visual percept despite our constant eye movements.

As a postdoctoral researcher in the Gegenfurtner lab, Avi's research is focused on understanding perception and eye movements in virtual reality (VR). Her work investigates color categorization in VR and the kind of eye movements we make in VR during perceptual tasks. To learn more about Avi's work, please visit her website here.

I'm interested in understanding the role of melanopsin activation and rods intrusion in color vision, brightness perception, and the pupillary light reflex.

My primary research interests lie in the field of color vision. In particular, I am focused on understanding what principles guide our perception of such color dimensions as saturation and hue in objects and realistic scenes. Additionally, I am interested in how this perception relates to more fundamental color mechanisms.

I attained my bachelor's degree in psychology, and my master's in cognitive neuroscience at the university of Groningen. My main research interest is the cognitive neuroscience of visual perception. Specifically, I use EEG, virtual reality and psychophysical methods to better understand size perception in the early visual areas of the brain.

I am interested in errors in human perception and performance, for instance, in the context of visual illusions and biases. My work is focused on spatial and temporal processing, eye-hand coordination, and face perception.

My research interests focus on visual perception and its neural mechanism. Currently, I am working on color vision, which includes heterochromatic brightness perception, pupillary light responses, color illusion, and color constancy.

I work at this multidisciplinary domain of brains, minds and machines aiming to answer how complex behaviour arises from neuronal activity. I compare neural networks of two organisations: biological versus artificial. My focus is visual information processing: oscillating in-between psychophysics of visual perception and computational modelling of vision.

My undergraduate and graduate degrees are both in computer science. My master's thesis was entitled "Computational Model for Object Recognition in Visual Cortex Based on Spiking Neural Networks". I started my Ph.D. in 2020. The topic of my dissertation is color vision and color constancy. In the first part, we are developing a deep neural network (DNN) model for color appearance. In the second part, we will identify how color vision works in a complex situated environment by using cutting-edge VR technology.

My research interests include: Color perception - adaptation, hyperspectral imaging, transparency, scene statistics. Material perception - perception of the kinematic properties of different materials. VR & online experimentation - adapting standard laboratory techniques for online experimentation and VR for better understanding color/material perception in 3D, naturalistic environments.

I attained my PhD in 2013 at SUNY College of Optometry with Dr. Qasim Zaidi and Dr. Barry Lee
