Postdoctoral Fellow

I am a postdoc in the Knight Lab at UC Berkeley. Working with Bob, my primary research focus is the neural mechanisms that facilitates successful interaction and communication between individuals, which I investigate using intracranial EEG recordings.

Before joining the Knight Lab, I completed my Ph.D. in the lab of Athina Tzovara at the University of Bern, Switzerland, where I investigated auditory processing across levels of consciousness.

Mattia F. Pagnotta

Mattia F. Pagnotta, Ph.D., is a postdoctoral scholar in the Helen Wills Neuroscience Institute at UC Berkeley. Mattia works with Bob Knight investigating the neural dynamics underlying cognitive control in the human brain. His long-term research goal is to uncover the neural architecture of distributed cognitive networks that allow us to flexibly achieve different types of cognition and behavior.

Before joining the Knight Lab, Mattia completed postdoctoral training with Mark D'Esposito (2021–2024) at UC Berkeley, with the support of the Swiss National Science Foundation (Early Postdoc.Mobility and Postdoc.Mobility fellowships). Before his time at UC Berkeley, Mattia obtained a B.Sc. in Clinical Engineering (2012) and a M.Sc. in Biomedical Engineering (2015) from Sapienza University of Rome (Italy), and a Ph.D. in Psychology (2020) from the University of Fribourg (Switzerland), completing the doctoral training of the Lemanic Neuroscience Doctoral School (Universities of Geneva and Lausanne).

Rebecca Stevenson

I use intracranial EEG to try to understand the neurophysiological basis of learning and memory. I received my PhD in 2019 from the University of California, Irvine and am currently a postdoc in the Knight lab at the University of California, Berkeley where my research will focus on prefrontal contributions to learning and memory.
