NSDF All Hands Meeting — April 2023
The third National Science Data Fabric (NSDF) in-person meeting was held at the San Diego Supercomputer Center in La Jolla, California on April 12-13, 2023.
Keynote
Maria Elena Monzani, Stanford University
Data-Intensive search for Dark Matter with the LUX-ZEPLIN experiment

The nature and origin of dark matter are among the most compelling mysteries of contemporary science. This talk described the leading effort in that search, the LUX-ZEPLIN (LZ) detector — 10 tons of liquified xenon gas maintained at almost atomic purity and stored in a refrigerated titanium cylinder a mile underground in a former gold mine in Lead, South Dakota. During its science run, LZ is projected to accumulate a massive dataset of many petabytes of data and record several billions of particle interactions, only a handful of which might be produced by potential dark matter candidates. Identifying the dark matter signals in this amassment of data represents an extreme “needle in a haystack” problem and requires leveraging advanced detector design and state-of-the-art machine learning algorithms.
Bio
Maria Elena Monzani is a dark matter data wrangler. Her research field is Astroparticle physics, which focuses on topics at the intersection between particle physics and astrophysics/cosmology, using the tools of data-intensive science. She received a dual Ph.D. from the University of Milano and the University of Paris 7, performing research with the Borexino experiment that measured neutrinos produced by the Sun. She then held a postdoctoral position at Columbia University before joining SLAC in 2007 to work on the Fermi Gamma-ray Space Telescope. Today, Monzani is a lead scientist at SLAC and a senior Kavli Institute for Particle Astrophysics and Cosmology member at Stanford. She leads the software computing effort for the LZ Dark Matter Experiment and the science operations team for the Fermi satellite. She is also an Adjunct Scholar at the Vatican Observatory.

Venue
The event was hosted at the San Diego Supercomputer Center on the UC San Diego campus in La Jolla, CA.
San Diego Supercomputer Center’s Auditorium E-B212 located on the ground floor of SDSC’s east entrance, just off the driveway on Hopkins Dr, close to the Hopkins Parking Structure, Northwest end of UC San Diego campus.
The San Diego International Airport (SAN) is the closest airport to UC San Diego and SDSC.
For driving directions see the SDSC visitor page
