Dr. Roberta Giusteri

Postdoc in the Space Interferometry group

What is your current position at our institute?

I am a postdoc in the Space Interferometry group.

What is your academic education?

  • Bachelor degree in physics
  • Master degree in astrophysics
  • PhD in physics

What were your previous academic positions?

  • one-year fellowship after the PhD

Can you please describe your research in general terms?

I am involved in the LISA project, a space mission planned for the detection of gravitational waves. These are ripples in the curvature of spacetime, generated by the acceleration of massive objects. LISA will be able to detect, for instance, gravitational waves originating from the first black hole seeds but also those from massive black holes coalescences. A major noise source which is expected to deteriorate the LISA sensitivity in the mHz band is the so-called geometric tilt-to-length (TTL) noise. This arises as a coupling between an angular vibration of a system component into the optical measurement and it is caused by misalignments within the optical system. My major task regards the calibration and subtraction of TTL noise using simulated LISA data.

Please let us know why you chose the Max Planck Institute for Gravitational Physics for your research.

I chose the Max Planck Institute for Gravitational Physics because the LISA group working at the institute is involved in many aspects of the project and comprises many experts. I think this is an environment with great expertise.
