Giorgio Gratta
Ray Lyman Wilbur Professor
BioGiorgio Gratta is a Professor of Physics at Stanford university and the current Physics department chair. Gratta is an experimentalist, with research interests in the broad area of the physics of fundamental particles and their interactions. While his career started with experiments at particle colliders, since at Stanford Gratta has tackled the study of neutrinos and gravity at the shortest distances.
With two landmark experiments using neutrinos produced by nuclear reactors, Gratta and collaborators investigated the phenomenon of neutrino flavor mixing, in one case reporting the first evidence for neutrino oscillations using artificial neutrinos. This established the finite nature of neutrino masses. The same experiment was also first to detect neutrinos from the interior of our planet, providing a new tool for the Earth sciences.
As a natural evolution from the discovery of neutrino oscillations, Gratta has led the development of liquid Xenon detectors in the search for the neutrinoless double beta decay, an exotic nuclear decay that, if observed, would change our understanding of the quantum nature of neutrinos and help explaining the asymmetry between matter and antimatter in the universe. Gratta is currently the scientific leader of one of the three very large experiments on the subject, world-wide.
In a rather different area of research, Gratta’s group is studying new long range interactions (or an anomalous behavior of gravity) at distances below 50 micrometers. This is achieved with an array of different techniques, from optical levitation of microscopic particles in vacuum, to the use of Mössbauer spectroscopy and, most recently, neutron scattering on nanostructured materials. -

Postdoctoral Scholar, Biology
BioI am an ecologist primarily interested in patterns and processes of biodiversity and community assembly. I am curious about the functional, historical, and evolutionary processes that act to bring species together in space and allow them to coexist. My past work has largely examined these questions in seagrass systems, focusing on assemblages at the scale of meters to multiple continental coastlines. In the Daru Lab, I plan to leverage large sets of organismal distribution data to answer questions about how functional traits and species interactions shape regional biotas, and develop tools to visualize and analyze these assemblages in space.
