Alessandra Corsi, Ph.D.


I am Professor of Physics and Astronomy at Texas Tech University (TTU). My research focuses on multi-messenger time-domain astronomy, with emphasis on relativistic radio transients and gravitational wave physics.  Please check the links below for more info!

My research is funded by the National Science Foundation from which I also received a CAREER award. I was one of the key players in the discovery of the radio afterglow from GW170817, the first LIGO binary neutron star merger. In 2017 I had the opportunity to report on this discovery at the NSF press conference hosted at the National Press Club. I am PI of several guest investigator programs funded by NASA. DOE funds part of my research on data science applications to multi-messenger astrophysics. 

I am honored to be a Fellow of the American Physical Society, a recipient of the Edith and Peter O'Donnell Award in Science of The Academy of Medicine, Engineering and Science of Texas (TAMEST), and an Italian National L'Oreal-Unesco Awardee for Women in Science. I am also a Fellow of the Research Corporation for Science Advancement (Scialog) in Time Domain Astrophysics. In 2020 I was selected as one of the ``SN 10: Scientists to Watch'' by Science News. I am fortunate to be among the recipients of one of the 2022 New Horizons in Physics Breakthrough Prizes.

I am a member of the LIGO Scientific Collaboration and I work with a talented group of students, post-doctoral researchers, and collaborators - see About Me & My Group. At TTU I teach a variety of courses, from large introductory astronomy courses for non science majors, to upper-level and graduate Astrophysics and Physics courses.
