-At Trento University, my research activity focused on the study of the
-limits for achieving near perfect free-fall of macroscopic test masses
-for the observation of gravitational waves. I conducted on-ground
-measurement of small force disturbances acting on the free-falling
-test masses of the LISA space low-frequency gravitational wave
-detector and its precursor mission LISA Pathfinder, exploiting the
-femto-Newton level sensitivity of a torsion pendulum.  I performed the
-experimental activity, I developed data analysis routines, I designed
-and implemented upgrades to the torsion pendulum system, improving its
-sensitivity and pushing the limits of small force metrology.  I lead
-the initial development of a low-noise torsion pendulum angular
-position read-out based on an heterodyne wavefront-sensing
-interferometer with nanoradian sensitivity. I collaborated to the
-development of the LTPDA Matlab Toolbox.
+Ultra-stable lasers are essential optical atomic clocks, quantum
+devices based on cold atoms, and quantum communications.  Better laser
+frequency stability will improve optical atomic clocks timekeeping
+stability and will enable more stringent fundamental physics tests
+that will challenge our understanding of the universe.  Cryogenic
+high-finesse optical cavities allow to overcome the thermal noise
+limit of room-temperature optical cavities and represent the
+state-of-the-art in laser frequency stabilization.  I develop
+cryogenic optical cavities targeting even better laser frequency
+stability by operating at lower temperatures and employing new
+designs, novel mirror technologies, and different materials.
+
+Optical atomic clocks are the most accurate measurement devices ever
+realized and are set to replace microwave Cs clocks as definition of
+the second.  I contributed to the development and systematic
+uncertainty evaluation of NIST's Yb optical lattice clocks that made
+these clocks the world's most accurate optical clocks.  I contributed
+to the measurement campaigns that compared NIST's Yb optical lattice
+clocks with other optical atomic clocks and with microwave primary and
+secondary frequency standards via optical fiber links and satellite
+microwave links.  The unprecedented accuracy and the agreement
+demonstrated between the clocks realized an important milestone toward
+the future redefinition of the second.

+Exploiting ultra-stable lasers for scientific and technological
+applications most often requires transferring their exquisite
+frequency stability to oscillators operating at a different
+frequency. I developed a fiber-based optical frequency comb system
+that realized optical frequency stability transfer between lasers
+widely different wavelength with unprecedented and unsurpassed
+frequency stability. Low phase noise microwaves sources are paramount
+for many applications, including precision metrology, deep-space
+navigation, coherent radar, and wireless communications. In
+collaboration with industrial partners, I developed a fiber-based
+optical frequency comb system for photonic microwave generation with
+unprecedented and unsurpassed low phase noise and zeptosecond-level
+absolute timing noise. This system has then been commercialized.
+
+Gravitational waves observations are revolutionizing astronomy and
+astrophysics. Detecting gravitational waves relies on
+interferometrically measuring the distance between test-masses in near
+perfect free-fall.  I conducted on-ground measurement of the small
+force disturbances acting on the test-masses of the LISA space
+gravitational waves detector exploiting the femto-Newton level
+sensitivity of a torsion balance.  I identified and modelled an
+unexpected increase of Brownian noise from residual gas molecules
+collisions in constrained geometries, with repercussions on the design
+of LISA and second generation ground-based gravitational wave
+detectors. I contributed to the design of the LISA Pathfinder mission
+for the in-flight testing of the concept of low-frequency
+gravitational waves detection in space and that validated the
+disturbance model developed from the on-ground measurements.
