Welcome to the Mazzucato Lab
|
Our lab is focused on elucidating the neural basis of sensory perception, decision-making, and associative learning.
To study these and other questions, we use methods from statistical physics, information theory, machine learning, and dynamical systems. We combine analysis of neurophysiological data from large populations of neurons in behaving animals with theoretical models based on neural networks. Our lab is passionate about creating an inclusive environment promoting diversity. We embrace a notion of intellectual community enhanced by diversity along a number of dimensions, including race, ethnicity and national origins, gender identity and presentation, disability, class and religion. We aim at fostering greater creativity and encouraging collaborative innovation and interactions.

Our lab will take part to the Academic strike in support of Black lives on June 10th 2020. We will abstain from academic activities and devote our lab meeting to discussing data on systemic racism in academia and concrete ways to address it in our practices.
Here is an explanation of what it means to strike, a FAQ, and an awesome list of resources on fighting racism in academia. The preprint server arxiv.org will participate in the strike as well thus amplifying the action worldwide. This is a link to the form pledging your support. |
