Léa Maitre
Assistant Research Professor at ISGlobal](https://www.isglobal.org/en/our-team/-/profiles/18762)), the Barcelona Institute for Global Health, and coordinates the Exposome Hub](https://www.isglobal.org/en/exposome-hub)) initiative, promoting innovation, collaboration and communication about exposomics.
Favorite metabolite
Neurosteroids](https://en.wikipedia.org/wiki/Neurosteroid))
Neurosteroids, also known as neuroactive steroids, are endogenous or exogenous steroids that rapidly alter neuronal excitability through interaction with ligand-gated ion channels and other cell surface receptors.
