Dr. Federico Fraternale

RESEARCH SCIENTIST I, CSPAR

Biography

Dr. Federico Fraternale is Research Scientist I at UAH -- CSPAR since November 2019. Federico is an expert of turbulence and wave motion in fluid flows and astrophysical plasmas such as the solar wind. He received his cum laude Ph.D. in Aerospace Engineering from the Politecnico di Torino, in Italy, in 2017. During his Ph. D., Federico focused on theoretical aspects of wave-packet dispersion and transition to turbulence in shear flows, and developed some procedures to perform multi-scale analysis of incomplete solar-wind time series.

Federico is currently involved in a NASA project on turbulence and dissipative processes in the outer heliosphere and in the local interstellar medium. Besides, Federico has been a European-level rowing athlete and instructor, and passionate ski mountaineer.
