Valerio’s studies concern the analysis of the Cassini radar altimeter data in order to derive the most accurate estimations of Titan’s surface dielectric parameters by means of a stochastic inversion approach based on Monte-Carlo simulations. After having worked for estimating equatorial dunes’ height, now Valerio matured a great interest for Titan’s liquid bodies, specifically he is characterizing rivers and canyons in the polar regions and assisting Marco Mastrogiuseppe in the determination of radar bathymetry and composition of Titan’s seas.

Sam’s research is focused on understanding the evolution of the surfaces of planetary bodies. If we can understand the morphologies, by describing and quantifying the topographic shapes of a planet’s surface, we can build process-based models that explain their evolution through time. Beginning with qualitative observations of a surface through geomorphological mapping, we then build numerical models that match those observations. This methodology can apply to just select regions on planets like Mars, to the hydrologically active poles of an icy moon like Titan, to sedimentary worlds like Comet 67P/Churyumov-Gerasimenko. The surfaces of all these bodies are governed by the motions of individual particles, and so understanding the sediment transport pathways on these bodies helps us to understand the evolution of the landscape as a whole. When not exploring the solar system, Sam enjoys adventuring around the many outdoor environments of the Finger Lakes region.

Paul currently works on observing and studying clouds and atmospheric dynamics of Titan. Currently, he uses the SINFONI instrument on the VLT to make spectroscopic observations to monitor the presence and characteristics of clouds. He is additionally interested in various types of instrumentations, having worked on a variety of instruments to date including ACTPol, BLAST, NIRSPEC, a proposed near-IR spectrometer for the Mars 2020 Rover, and is currently designing an FTS for measurements in submillimeter wavelengths.

Nics current research uses the RADAR aboard the Cassini satellite to study Titan altimetry, the measurement of altitude above the surface, and bathymetry, the measurement of depth of the lakes. In addition to Titan he is interested in Europa, Enceladus, Ganymede, Triton, and Mars. Specifically he wants to learn about these bodies’ geomorphology, crater morphology, topography, and surface and interior processes. Nic also has an interest in developing, designing, and building instrumentation to go to or study these places. Outside of his research, Nic has a passion for video games, space operas, anime and manga.
