About me

My research focuses on understanding how the brain regulates behaviours and physiological states via neuropeptidergic signalling. Currently, my main focus is the role of central arginine vasopressin (AVP) circuits in pain, fear and stress. Additionally, I am interested in the neural plasticity induced by lactation during motherhood, which is an extreme physiological challenge that leads to complex cellular and circuit-level reorganisations in the brain. To study these phenomena, I use novel transgenic rat models, viral vectors, chemogenetics, optogenetics, advanced light microscopy and quantitative 3D image analysis techniques. I am also collaborating on various other projects related to oxytocinergic and vasopressinergic brain circuits.

Quirin holds a PhD in Comparative Neuroscience (summa cum laude), as well as an MSc and a BSc in Biology. He is a senior staff scientist on our team and heads the Microscopy Core Unit at the Preclinical Research Core Facility.
