The current administration in the US has, through various funding agencies such as the NSF and NIH, has recently suspended virtually all federal grants to my home university, UCLA (including my own personal grant, although that is far from the most serious impact of this decision), on the grounds that UCLA was “failing to promote a research environment free of antisemitism and bias”. One can certainly debate whether these grounds were justified, or whether they merit the extremely draconian damage to the very research environment that this decision is claiming to protect, but if nothing else this unprecedented decision does not appear to have followed the usual standards of due process for actions of this nature; for instance, there appears to have been no good faith effort by the administration to receive a response from UCLA to its allegations before implementing its decision.

The suspension of my personal grant has a non-trivial impact on myself (in particular, my summer salary, which I had already deferred in order to allow the previously released NSF funds to support several of my graduate students over this period, is now in limbo), and now gives me almost no resources to support my graduate students going forward; but this is only a fraction of a percent of the entire amount being suspended. A far greater concern is the impact on the Institute for Pure and Applied Mathematics (IPAM) https://www.ipam.ucla.edu/, which despite receiving preliminary approval earlier this year for a new five-year round of funding (albeit at significantly reduced levels) from the NSF, now only has enough emergency funding for a few months of further operation at best if the suspension is not lifted.

IPAM (pictured here in a photo I took today), as one of the six NSF-funded math institutes, has been a great success since its founding in 2000. Its specialty is creating three-month programs where participants (both junior and senior) from two or more fields of mathematics, science, or industry interact through workshops, participant-driven seminars, and informal interactions, centered around a theme that had been identified as particularly fertile for bringing together two or more otherwise disparate communities.

One well-known example that I was involved many years ago was the 2004 program https://www.ipam.ucla.edu/programs/long-programs/multiscale-geometry-and-analysis-in-high-dimensions/ on Multiscale geometry and analysis in high dimensions, where the organizers had identified the potential for bringing together pure mathematicians whose work involved geometry at multiple scales with scientists interested in such applied topics as signal processing or the accurate modeling of materials. I participated extensively in this program, and in particular interacted quite a bit with one of the organizers (Emmanuel Candes) as well as Justin Romberg, leading to several foundational papers in the field now known as "compressed sensing", which permits (in certain circumstances) the rapid acquisition of high-resolution images or other information from a relatively small number of measurements. (Perhaps the most well known applications of the compressed sensing algorithms that came out of the work of Emmanuel, myself, Justin, David Donoho, and others was the ability to speed up the time required for a medical-grade MRI scan by up to an order of magnitude.)

Some accounts claim that Emmanuel and I actually started collaborating at the preschool that both of our children attended at the time, but the truth is that our main collaboration actually started at IPAM; the fact that we met on a near-daily basis at the preschool was very useful to continue the collaboration, but it was not exactly an ideal environment to initiate it.

I have been involved in several other very interesting IPAM programs since then; for instance, in 2023 I was the lead organizer in an IPAM-hosted workshop on Machine Assisted Proof https://www.ipam.ucla.edu/programs/workshops/machine-assisted-proofs/, which turned out to be a very well-timed event (occurring a few months after the launch of ChatGPT, for instance), bringing together pure mathematicians, computer scientists, and several people from industry and opening important channels of communication between researchers in such topics as proof formalization, machine learning, large language models, computer algebra solvers, and satisfiability solvers. (I previously posted on my experiences at that workshop at https://mathstodon.xyz/@tao/109858184238417737 .) My experiences at that workshop, as well as the connections made, permitted me to get up to speed on the latest developments in all of these areas, which now encompass a large portion of my current research interests.

But perhaps the biggest positive contributions of institutes such as IPAM is not on senior faculty such as myself (who often have other resources and connections to draw upon), but on early career researchers, especially those from less well known institutions who might not otherwise have many opportunities to interact with the researchers at the emerging interface between two or more fields that were just beginning to become interconnected. When I was a postdoc, I experienced that opportunity myself in 1997 at a different NSF-funded institute (MSRI, now known as SLMath) in a program https://www.slmath.org/programs/60 on harmonic analysis, which was instrumental in setting up several extremely productive collaborations in my early career. Many of my colleagues and collaborators can also testify to positive early-career experiences in such institute programs as similarly unlocking their own research potential. Losing one of these institutes would have major negative impacts on the next generation of mathematical scientists.

@tao I'm sympathetic, but I'm surprised that you haven't called a spade a spade here. The administration is cracking down on universities where students spoke out about Palestine, and you didn't say the word Palestine once. You're playing their game. Disappointing.

For those wondering about this, you can read about Project Esther https://www.nytimes.com/2025/05/18/us/project-esther-heritage-foundation-palestine.html

Inside the Heritage Foundation’s Plan to Crush the U.S. Palestinian Movement

Even before President Trump was re-elected, the Heritage Foundation, best known for Project 2025, set out to destroy pro-Palestinian activism in the United States.

Project Esther: A Nexus Project Briefing

Project Esther reframes protest as antisemitism and dissent as a national security threat. It was developed with minimal Jewish input, it advances a far-right agenda, not Jewish safety. It is already being implemented: visa revocations, university funding cuts, faculty targeting. The Nexus Project is leading a national response to Project Esther, rooted in democratic values and pluralism.

@tao it is sad that funding has been pulled.
But many, many faculty and academics stood silent while a "Jew exclusion zone" was erected at UCLA. For months the university dithered while Jewish students were harassed and intimidated

The harassment was not unlike what early times in Nazi Germany looked like.

Many academics believe they can just put their heads down and "do science". But why not speak up? Because of fear?

Palestine viewpoints should not be suppressed, but neither should Jewish students. Moral courage would have compelled academics to take a stand that said, we support free speech, but we do not condone harassment.

@Epluspi @tao you are a dirty MAGA fascist liar and you know it

@burnoutqueen @Epluspi @tao and why is that? all he said is that while views on Palestine should not be suppressed through manipulation of federal funds - colleges and faculty WERE turning a blind eye to very obvious antisemitic demonstrations on campus and sometimes supported them, its not being a “fascist lier” its called stating a fact.

And that absolutely does not mean that this administration is effective at mitigating antisemitism because in my opinion they only amplify it with such actions, but the basis on which they are operating with this specific action is true and thus they kill two birds with one stone, they blackmail academia AND make sure to invalidate future outcries of antisemitism by making sure it will be labeled as nothing more than a mean to control/blackmail with.

@tao

I'm sorry that these sorts of actions are happening to you and your colleagues across your nation. Academia is already often precarious and critical work not well understood by those outside of any given speciality can be easily destroyed by these actions. 😢

On a personal note, I love your mention of collaborating at the preschool. One of my favourite things about Euler was his love of children and tendancy to work with one or more of them in his arms or the immediate surroundings. 🙂
