Constructing space from moving gaze

I am a postdoctoral fellow in the lab of Christian Doeller at the Kavli Institute for Systems Neuroscience in Trondheim (Norway) and the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig (Germany). I study the links between human vision, viewing behavior and memory.

I am especially interested in how we perceive and memorize space, and how our knowledge about the world shapes the way we see and interact with it. I address these questions using neuroimaging and eye tracking combined with psychophysical and virtual reality experiments. My work is complemented by machine learning to characterize brain activity in sensory and memory regions and how they interact. I also enjoy methods development to push the boundaries of how we study these processes altogether. Read more about my research here.

I look forward to soon be starting as a postdoctoral fellow in the lab of Christopher Baker at the National Institute of Mental Health in Bethesda (USA).

Functional imaging of the human medial temporal lobe.
A neuroscientist's guide to fMRI pulse sequence optimization

The medial temporal lobe (MTL) is difficult to image with fMRI due to magnetic field inhomogeneities and low signal-to-noise ratios. Here, I compiled some information about fMRI pulse sequences and how they affect your data, along with a few tips on how to get a good signal in the MTL. Find it here on Open Science Framework!

Behavioral encoding modeling

This code creates, fits & tests an encoding model of virtual head direction using simulated fMRI voxel time courses.

It can be easily adapted for other behavioral domains & imaging techniques (MEG, 2p-imaging...) to study the neural underpinnings of behavior across species.
