Instrument/Experiment Postdoctoral position at the LIGO Laboratory

The Laser Interferometer Gravitational-Wave Observatory (LIGO) has as its goal the development of gravitational wave physics and astronomy. The LIGO Laboratory is managed by Caltech and MIT, and is funded by the National Science Foundation. It operates observatory sites equipped with laser interferometric detectors at Hanford, Washington and Livingston, Louisiana, which have made the first confirmed detection of gravitational waves. A vigorous LIGO Laboratory R&D program supports the development of enhancements to the LIGO detector and development of future detectors and detector technologies.

The LIGO Laboratory anticipates having one or possibly more experiment/instrumentation postdoctoral research positions at one or more of the LIGO sites – Caltech, MIT and at the two LIGO Observatories in Hanford, WA and Livingston, LA – as positions become available. Hires will be made based on the availability of funding. Successful applicants will interact with faculty members Rana Adhikari and Lee McCuller (Caltech) and Matt Evans and Nergis Mavalvala (MIT) as well as the Lab’s extensive network of experienced researchers and personnel. Successful applicants will be involved in the operation of the world’s most sensitive interferometers, and/or the R&D program for future detector improvements. Examples include optimizing the squeezing of the vacuum to minimize quantum noise, a prototype cryogenic interferometer, using machine learning for nonlinear feedback control, devising techniques to quell opto-mechanical instabilities that can disable the interferometers, and designing new suspension systems for 100 kg test masses. We seek candidates across a broad range of disciplines. Expertise related to modeling, data analysis, electronics, laser and quantum optics, vibration isolation and control systems is desirable. Most importantly, candidates should be broadly trained scientists, willing to learn new experimental and analytical techniques, and ready to share in the excitement of building, operating and observing with a gravitational-wave observatory. A list of former postdocs at LIGO Hanford and LIGO Livingston is available here . Appointments at the post-doctoral level will initially be for one-year with the possibility of renewal for up to two subsequent years.

Applications for postdoctoral research positions with LIGO Laboratory should indicate which of the LIGO sites (Caltech, MIT, Hanford, or Livingston), if any, are preferred by the applicant, and which (if any) are likely to be unworkable. Caltech and MIT are Affirmative Action/Equal Opportunity employers. Women, minorities, veterans, and disabled persons are encouraged to apply. Applications should be submitted through Academic Jobs Online and include curriculum vitae , list of publications (with refereed articles noted), and the names, addresses, email addresses and telephone numbers of three or more references. Please also attach a research statement describing past experience and current and future research interests (3-4 pages). Applicants should request that three or more letters of recommendations be submitted directly through Academic Jobs Online. Consideration of applications will begin on November 15 but will also continue throughout the academic year and until all positions are filled.

Precision Gravitational Wave Astronomy: From Theory to Discovery July 27-31 in Sexten, Italy

Gravitational wave astronomy is rapidly becoming a precision science.
With upcoming detectors on the ground and in space, we will be able to detect black holes at the edge of the observable universe and test general relativity in its most extreme regimes. However, as the measurements become more sensitive, so does the challenge of interpreting them. Small anomalies in the data could point to new physics—or just reflect environmental effects, modeling uncertainties, or instrumental noise. This workshop, part of the ERC synergy GWSky project, will bring together researchers working across theory, simulations, and observations to tackle this challenge, and build the tools and frameworks needed to make sense of future discoveries.
This workshop is by invitation only

School of Basic Science 2026, August 30 – September 5 in Campagna, Italy

Campagna School of Basic Science 2026
Advanced Methods for the Physics of the Universe 

Joint initiative with Korea Institute for Basic Science (IBS)
Con il patrocinio del Dipartimento di Fisica e Astronomia "Galileo Galilei", Università di Padova

The first edition of the Campagna School of Basic Science will focus on advanced theoretical methods for studying the physics of the universe. The program will feature four courses covering the following topics: inflationary cosmology; cosmological correlators; amplitude methods for gravitational waves; and topological data analysis techniques applied to cosmology. The aim of the school is to explore interdisciplinary subjects, fostering discussion and collaboration among participants.

In addition to the lectures, two public events will be organized to celebrate important historical characters who lived in Campagna. The first honors Giordano Bruno, often regarded as one of the earliest true cosmologists for his pioneering ideas about cosmic pluralism and the concept of an infinite universe. The second commemorates Juan Caramuel, considered the first mathematician to publish a rigorous study of non-decimal numeral systems, including the binary system, in 1670, during his stay in Campagna.

The School will be held as part of the second edition of “Campagna Science Week,” whose first edition took place in 2025 and included a conference.

Topics and Lecturers

  • Inflationary Cosmology – Robert Brandenberger (McGill University, Canada)
  • Cosmological Correlators – Paolo Benincasa (Santiago de Compostela, Spain)
  • Amplitude Methods for Gravitational Waves – Carlo Heissenberg (IPhT, Saclay, France)
  • Topological Data Analysis for Cosmology – Matteo Biagetti (RIT, Area Science Park Trieste, Italy)

Public Lectures

  • Giordano Bruno Seminar – Thibault Damour (IHES, Bures-sur-Yvette, France)
  • Juan Caramuel Seminars – Donato Bini (IAC – CNR, Italy) and Gabriele Gionti S.J. (Specola Vaticana, Italy)

NEHOP 2027 – New Horizons on Primordial Black Hole Physics, June 14-18, 2027 at University of Patras

After four very successful editions in Naples, Edinburgh, Brussels and CERN we are delighted to announce the fifth New Horizons in Primordial Black Hole Physics (NEHOP'27) workshop. This year, it will take place in the beautiful city of Patras, Greece, from 14th to 18th of June, 2027.

This workshop event aims to nurture discussions and bring together experts on the broad topic of Primordial Black Holes (PBHs). From their phenomenological implications, their possible relationship to extant problems in the SM (dark matter, neutrino masses, baryon asymmetry, inflation), their theoretical underpinnings and origin, to the multi-messenger signals that are motivating state-of-the-art experimental developments.

While most talks will consist of short, technical presentations by young researchers, a small number of expert talks will be included to both provide comprehensive overviews and present new results on key topics.
