Imagine we’re in an elevator and you have until we reach our floor to pitch your project/idea.

What’s your elevator pitch?

How do we perceive the world, and why does our brain need to inhibit most of the signals in order for this to work? In tight collaboration with our colleagues in IN-Code, this project aims to provide answers to these questions using two complementary types of inhibitory interneurons as a model.

What fascinates you about your project?

Internally-generated top-down information is a family of essential and ubiquitous signals that we know next to nothing about.

How did you come to work in the field of Neuroscience?

Since childhood I was keenly aware that the entire world as well as our complete self and personality all exist exclusively in our brain. Hence, I was drawn to Neuroscience from an early age.

What does your family think you do for a living?

My partner thinks I have the best job in the world, and – most of the time – I agree.
