Maximiliano Isi

I am a postdoctoral researcher at the Massachusetts Institute of Technology, supported by NASA through an NHFP Einstein Fellowship. I am also an associate at the Flatiron Institute in NY. I obtained my PhD in Physics from the California Institute of Technology in 2018. I work on the analysis of gravitational wave signals detected by interferometric detectors, like the advanced Laser Interferometer Gravitational-wave Observatory (LIGO). I am especially interested in using these signals to probe Einstein's General Theory of Relativity (more about my work). I am a member of the LIGO Scientific Collaboration.


LIGO Hanford Site

I am interested in using gravitational waves to test Einstein's General Theory of Relativity. In particular, I have focused on ways to measure the polarization content and speed of gravitational waves by using continuous sources, like pulsars. I am also involved in projects looking into transient signals, like those whose detection was announced in February, 2016.

Legislative Staffers Caltech Holiday Reception

I enjoy spreading interest in gravitational waves (and science in general!) by reaching out to local schools, as well as the wider community in Pasadena. Here are some examples of the latest events I have participated in:

  • Legislative Staffers Caltech Holiday Reception (Dec 1, 2016)
  • Washington STEAM Magnet School Outreach Night (Nov 9, 2016)
  • Iberoamerican High-school Physics Olympiads in Carmelo, Uruguay (Sept 28, 2016)
  • High-school Physics Teachers Meeting in Piriapolis, Uruguay (Sept 21, 2016)
  • Longfellow Elementary Stargazing and Science Night (Feb 26, 2016)

I also make an effort to use social media to share my enthusiasm for science.


Following the announcement of the discovery of gravitational waves, I had the chance to talk to a few media outlets, mainly from my native Uruguay. Some interviews available online are linked below:
