Sam Speaks Science




A passion is a thing you talk about, not something you keep secret.

Over the years, I have come to realise that a lot of driven scientists were struggling to share their passion and their vast knowledge, even with their close colleagues. Because enthusiastic experts are delightful to learn from, I created SamSpeaksScience to empower scientists to unleash their - too often confined - knowledge and passion. Science is a beautiful discipline, a noble endeavor that the world - not just a happy few - should benefit from. In a time where facts have become untrustworthy for some, it is important to know how to have an impactful discourse about science and scientific knowledge.

How does our brain interpret our environment? How are photons, smells, air pressure waves transformed into electric signals to create meaningful perceptions? I have studied olfaction and hearing, at the molecular level, local neuronal network and large ensemble level to try to answer those questions. I had the thrill to hear neurons fire action potentials in real-time with both in vitro and in vivo electrophysiological recordings ; I saw the brain of a mouse literally light up with each breath as it was smelling banana with fluorescence in vivo imaging. In my last couple of years in a lab, I became interested in sensory perception in the context of schizophrenia. What if the inability to concentrate was coming from a deficit in filtering out irrelevant sensory stimuli?

I started my research as a PhD student at the Pasteur Institute, did a first post-doc at the Rockefeller University in New-York and a second post-doc at the University of Geneva.

I have an H index of 8 (list of publications here).


  • Student at the École Normale Supérieure (ENS Ulm, Paris)
  • MSc in Neuropharmacology, ENS - Univ. Paris 7
  • PhD in Neuroscience, University Paris 6


  • English (fluent)
  • French (native speaker)


In a workshop, I love creating a group dynamic that allow attendees to work together, to observe and learn from each other. I am currently teaching at the Conférence Universitaire Suisse Occidentale (CUSO), the Réseau romand de Conseil, Formation et Évaluation (RCFE) and the University of Geneva for the french 3-minute thesis competition (ma thèse en 180 secondes, mt180).

I also run workshops for a number of institutions and companies (Seedstars World, BSNL, University of Lyon, Medworld...).


One-on-one sessions allow me to delve into the knowledge of an expert - a highly stimulating experience. I have been coaching TEDxLausanne speakers since 2012. I have been working with scientists (Doctoral students and professors) from the University of Geneva (UNIGE), Lausanne (UNIL) and the Ecole Polytechnique Fédérale de Lausanne (EPFL) for ERC consolidator grant interviews, job interviews and presentations to lay audiences.

Interface Art/Science

Interesting things happen at the interface... I am involved in a number of projects with The Catalyst. Past projects include a science film hackathon, an escape game in a museum, a play...
