Does RFK refer to any other existing papers that investigate purported tylenol-autism link, besides the one (very weak) meta-analysis by Prada et al? Genuinely curious, because I've only seen that single paper mentioned in most news reports.

In case you want to take a break from ~everything else going on~ to read a lil bit about causal mediation analysis, sample selection bias, and disparities in liver transplantation decisions... here's a new paper: arxiv.org/abs/2509.01969

I wrote something about statistics under authoritarianism

This paper I contributed to may be of interest to both public health folks and philosophers of science — we outline a view of how to understand and operationalize “intrinsic health” as distinct from “no disease” (ffo of words like “emergence” and “operationalize”)

Zohran's victory is a glimmer of light in a very dark time <3

Support the brave staffers at @NIH! #BethesdaDeclaration actionnetwork.org/forms/add-na...

Join the AAUP and your dues go to support lawsuits like these against the Trump admin!

A powerful piece by Daniel Malinsky on why scientists must resist Trump’s authoritarian agenda: “In these times … scientists have a duty to dissent.” We completely agree. Ready to act? Join the #SummerFightForScience now (1/2)➡️ www.theguardian.com/commentisfre...

I wrote something to say that scientists cannot afford to be 'apolitical' Scientists actually have the skills and the duty to join in the fight against authoritarianism www.theguardian.com/commentisfre...

My NIH-funded friends: please take 1min to post a public comment opposing this awful policy change that would expedite political interference in federal science funding www.federalregister.gov/documents/20...

Tag yourself! I'm the "NA" in the NIEHS budget line

OpenAI's "most powerful system" makes shit up more than half of the time. For its "o4-mini" model, the rate is ***79 percent***

Decades of research that American taxpayers have invested in is being imperiled at universities like mine. Our paper wrote about some of the projects affected www.columbiaspectator.com/news/2025/04...

Columbia faculty (700+ signatures!) urges our Trustees to do 6 things: 1. Stand up for higher ed 2. Fight back against federal attacks (sue!) 3. Protect our students 4. Preserve academic freedom & fac governance 5. Affirm tenants of DEI 6. Protect research & provide backup funding shorturl.at/6OLTJ

Join us TODAY at 12:30pm Haven Ave Plaza (at the medical center)! CUIMC Stands Up and Speaks OUT! We rally to say HANDS OFF our students, science, patients, classrooms, and community!

Spoke to an excellent intl student who was accepted to PhD programs in the US and is choosing to instead attend a program abroad due to fear and uncertainty re: the visa cancellations... Such a loss for the US :(

Trustees: listen to the faculty! Fight back!

MONDAY in NYC: Stand with Columbia faculty, researchers, physicians, & nurses calling on the the Columbia Board of Trustees to resist Trump’s assault students, patients, lifesaving research, & teaching. @aaupcu.bsky.social @psc-cuny.org @csmapnyu.org

Every single university president should be asked, in public, why they are not speaking out this way to support all the students currently detained without due process, and all those terrified that they will be next, on every campus in this country. Yes, including Columbia's acting president.

It was great to have @danielmalinsky.bsky.social give an excellent lecture on casual graph discovery in my network science class today!

I am I'm this picture and I don't like it

Over 200 CUIMC medical, public health, and nursing researchers, clinical, support staff, and students took a stand in Haven Plaza Thursday March 27th. Standing up to Protect our Research, Protect our Students, Defend Science, Academic freedom and voicing the need for Columbia to Fight Back!!!

RIGHT NOW: Columbia Irving Medical Center researchers are speaking out on how the Trump admin cuts to research funding will cause harm to millions of families in the US and worldwide.

Columbia University has failed to defend academic freedom & freedom of speech & allowed a great institution to be bullied & extorted into submission by an administration hellbent on contorting higher education to their will. The AAUP condemns this capitulation. We can & must fight back.

An important statement by 2000+ Jewish colleagues:

This evening, Columbia/Barnard faculty, Jewish leaders, immigrant advocates, and rabbis came together to demand the immediate release of Mahmoud Khalil. We will not be silent about this outrageous assault on free speech. We will not be silent in the face of an authoritarian takeover. #FreeMahmoud

Looking forward to this! Say hi if you're in Atlanta.

“Protecting our university from Trump’s cruel agenda means resisting his instrumentalization of antisemitism” – a new op-ed from some Jewish colleagues at Columbia www.columbiaspectator.com/opinion/2025...

It is barely February and I have already reached my emotional quota for peer review requests in 2025.

Good essay by @economeager.bsky.social FFO: Truth, Probability, and "Truth and Probability"

Hey look a new commentary on AI in healthcare! "Healthcare AI should be 'actionable,' and the change in actions induced by AI should improve outcomes. Quantifying the effect of changes in actions on outcomes is causal inference." academic.oup.com/jamia/advanc...

Helpful comment from Reviewer 3, on a paper analyzing data from an observational study: "would be better if you could validate in a clinical trial" Gee thanks! (This was their only comment)

The Columbia public health school published this Q&A about my work on causality & algorithmic fairness. Read on to learn how the IMF's imposed austerity policies post-2009 financial crisis led me down a path toward studying causal inference* *not among the intended effects shorturl.at/KkeWu
