The nomination packet should consist of
(i) an approx. one page nomination letter summarizing the specific achievements to date of the nominee;
(ii) a complete CV and a publication list of the nominee;
(iii) two letters of support from experts emphasizing the broad significance of all research contributions to date of the nominee; and
(iv) a proposed citation. Self-nominations will not be considered.
The entire packet should be bundled into a single PDF file and e-mailed to bronstein@cstq.org. Please use this address also if you need more information. Deadline for sending nominations is end of February.
The prize consisting of a certificate and a monetary reward will be presented during the Loops’26 International Conference on Quantum Gravity, to be held in Hangzhou, China, on 24–29 May 2026.
Historical Background
During the celebration of 25 years of Loop Quantum Gravity at Madrid, a new prize for post-doctoral scholars in loop quantum gravity was created. It is named after Matvei Petrovich Bronstein, who was the first to emphasize that quantum gravity requires a deep revision of classical space-time concepts. He wrote his PhD thesis on Quantization of Gravitational Waves in 1935. He clearly understood the limitation of applying the Bohr-Rosenfeld QED measurement analysis to gravity. He derived the quantum analog of Einstein’s quadrupole formula but emphasized the need to go beyond linearized gravity. For details, see the republication and translation into English of his 1936 paper on the quantum theory of weak gravitational fields [1,2]. He was considered by many as the brightest of the young Soviet physicists in the mid-1930s. He was arrested during the Great Purge on trumped-up charges in 1937 and convicted by a list trial and executed on the same day in 1938. An account appears in the afterword (external link) of ref. [3].

News from the Steering Board
The Steering Board (SB) established the International Society on Loop Quantum Gravity (ISLQG) as a registered non-profit organisation under US federal law with 501(c)(3) status in accordance with the Internal Revenue Code (26 U.S.C. § 501(c)3). Concretely, this means that the society has legal personality and will be exempt from most taxation. It can now receive donations with tax benefits for donors within the United States of America. For donors residing outside the USA, potential tax benefits depend on the tax laws of their country of residence.
The Steering Board is very happy to have completed this milestone and would like to express gratitude to Hal Haggard for all his work and all society members for their support throughout the process.
News from the Young Researchers' Working Group
The Young Researchers' Working Group (YRWG) launched an online survey to better understand interests and needs that young researchers in the community have. Junior members that have missed the communication or cannot participate in the survey online can reach out to the members of the working group by e-mail. Contact details can be found here.
The survey gathers feedback on the types of activities young researchers would find most valuable—such as journal clubs, panel discussions, early-career workshops, and similar initiatives. It also asks for young researchers' interest in contributing to the organisation of the working group.
Researchers are invited to contact the members of the working group directly by e-mail. The working group welcomes ideas, suggestions, or comments.
News from the Website Working Group
Careful readers of this website will have noticed subtle changes to structure and design. These updates are the work of the Website Working Group (WWG), which seeks to improve the readability and logical structure of the site. To discuss past updates and future plans, the steering board had a joint meeting with the website working group in early January. The working group presented ideas for future additions to the ISLQG website.
The members of the website working group invite readers for feedback. Contact details can be found here.
ISLQG Members' Blog
Last year, ISLQG launched an internal scientific blog. All members of the society are invited to contribute. The blog is available through the following link
There is now a new addition to the blog. The section New Papers includes automised new blog posts for each new paper from every member of ISLQG. The post will contain the title, list the authors and the abstract available from arXiv. The section New Papers can be viewed by all users of the blog. Users can follow any category to get notified when there is a new post published in that category. The society thanks Waleed Sherif (FAU Erlangen-Nürnberg) for integrating this new feature into the blog.
In case you are a member of the society but have not received an invitation to join the internal ISLQG blog yet, please contact Kristina Giesel. Contact details can be found here.

The Year 2025 in Review
Earlier news from late 2024 to December 2025 are summarised here, where we look back at what happened in the community during the past 15 months. We include reports from conferences, workshops and schools. In addition, we report on new faculty positions and the 2025 Blaumann Prize, which was awarded to Ali Akil and Qianhang Ding. Unfortunately, there were also two very sad news to share.
Sami Viollet, a PhD student in quantum gravity at Aix-Marseille University died on 02 February 2025 in a mountain accident. His teachers in Marseille, Alejandro Perez, who supervised Sami Viollet's PhD, and Simone Speziale speak about a talented young men, who will be remembered for his dedication, passion, and intellect, which left a lasting impact on everyone who was close to him. Their message to the community is available here.
A couple of months earlier, Jerzy (Jurek) Lewandowski died on 08 October 2024. He is credited among the researchers who most contributed to the development of Loop Quantum Gravity. In October 2026, a year after his death, the Banach Center in Warsaw organized a conference in his memory. Tomasz Pawłowski wrote a report about the conference, which is available here. More information about Jerzy Lewandowski can be found here. Personal memories have been collected at www.remembr.com/jerzy.lewandowski.
