Sobre

Adjunct Professor at UFRJ’s Physics Institute. Bachelor’s and master’s from UFMG and PhD from UFRJ, with a sandwich PhD period in Italy (2009). She completed postdoctoral fellowships at UFRJ, at IIP/UFRN, and at IQOQI (Austria) in Anton Zeilinger’s group. She was a Scientist in Residence at the School of the Art Institute of Chicago and a visiting professor at UMass Boston. She works in Quantum Optics and Quantum Information, focusing on foundations, entanglement, and imaging. She is an Affiliated Member of the Brazilian Academy of Sciences, serves on the editorial board of Quantum Science and Technology, and is a CNPq research productivity fellow. She was a JCNE (FAPERJ) fellow and a founding member of the Commission for Justice, Equity, Diversity, and Inclusion of the Brazilian Physical Society (SBF). She is interested in the relationship between art and science and in physics education, with an emphasis on promoting equity and diversity in physics.

About the research:

The Neurophysics project aims to investigate, with unprecedented precision, the mechanisms of spatial and temporal integration of the human visual system in the few-photon regime. The research lies at the interface between psychophysics, sensory neuroscience, and quantum optics, seeking to understand how the visual system processes light stimuli under extreme conditions close to the absolute threshold of vision. Since the 19th century, the classical laws of psychophysics have described the temporal and spatial summation of light perceived by an observer. However, it remains an open question how the visual system integrates individual photons over time and space. Recent advances in directional light sources and high-precision spatial and temporal modulation systems now allow these laws to be revisited under tight control of luminance, spectrum, and the temporal and spatial distribution of the light stimulus.
