After receiving an undergrad
degree in electrical engineering at the Politecnico di Milano, I moved to
astrophysics and to Germany for graduate school at DESY and the Humboldt Universität. There I
worked on the South Pole Acoustic Test Setup (SPATS),
an array of acoustic transmitters and receivers designed to measure the
acoustic properties of South Pole ice. In particular my thesis
(Humbold link to thesis)
focused on an acoustic retrievable transmitter, which we designed, built and
successfully used to measure the acoustic attenuation length. The project was
developed within the IceCube neutrino
telescope, to investigate the feasibility of acoustic detection of
astrophysical neutrinos.
I then spent a year at UC
Berkeley working with Prof. P. Buford Price and Dr. Ryan Bay. We logged
boreholes at the South Pole and at Dome C to detect dust and volcanic ash
layers which allow for the reconstruction of paleoclimate records. We also
scanned several ice cores from Greenland and Antarctica to study the microbial
content through observation of fluorescence at different wavelengths, and investigated the possibility of tagging microbes in
several thousands year old ice using flow cytometry.
From February 2011 until
August 2013 I was a postdoctoral researcher in the group of Giorgio
Gratta at Stanford University. I worked
on the Enriched Xenon Observatory (EXO), an experiment for the
search of neutrino-less double beta decay, located at the Waste Isolation Pilot
Plant (WIPP) in New Mexico. In 2012-2013 I was technical coordinator for
the experiment, supervising operations on site.
Since September 2013 I have
been a scientist at WIPAC in
Madison, WI. I work on digital optical modules characterization and IceCube
high energy extensions.
