In a new preprint, we combine modeling with school-level vaccine data to contextualize the risk of 'breakthrough infections' and impacts on the ongoing US measles outbreak. #idsky #episky www.medrxiv.org/content/10.6...

Models can be powerful tools to study associations in data. But do they reliably reveal the truth? 🚨 In our new study, @danlarremore.bsky.social and I show that the model used to estimate VE from test-negative designs (TNDs) may not translate to other correlates of risk. doi.org/10.1093/aje/...

Sometimes it feels really heavy to pretend everything is okay in our country and just keep doing research. It seems like the best thing I can do for my career is the worst thing I can do as a human being.

It really says something about the state of our country that I no longer believe banning LED headlights should be a top federal government policy priority… But I still hate them, to be clear 😑

How can diagnostic tests for infection support public health – and what challenges do we need to overcome to maximize their potential? Kristin Nelson, Tyler Brown, and I have a new article out digging into this exciting, complex issue: www.tandfonline.com/doi/full/10....

I have recently taken up watercolor as a relaxing after-work hobby. This piece captures a subtle sunset over the lake at my parents’ house in Tennessee!

6/ This is not a debate. That data is crystal clear. Since the 1996 Port Arthur massacre, Australia’s buyback program and strict licensing have kept mass shootings to ~0–1 per year. The U.S. has about 400–650 mass shootings annually and over 46,000 gun deaths each year. It’s not even close.

The MIDAS Trainee Executive Committee is recruiting new members for 2026! 🤓 This is a great opportunity for grad students & postdocs in infectious disease modeling to gain experience organizing events & connect with peers. Applications are due by 9am ET on 1/1/2026, link in flyer & alt text.

Every fall, for the last 13 years, I have worked with CDC and WHO colleagues on a report in MMWR to update the estimates of the global burden of measles disease and mortality. This year we were already planning to publish in WER because of restrictions on communication between WHO and CDC.

1/ Hey, do you need some #goodnews? I know I do. Between the noise and the chaos, it helps to stop and remember what progress actually looks like. Here are four public health wins to give you some good news for the week 👇

Why, in this incredible world of technological advancements, are published inline equations still blurry? 😵‍💫

#Vaccines save babies! And they do it so well when we allocate resources to achieve high vaccination rates instead of meh vaccination rates 💉

1/ Today and tomorrow, #ACIP —the external body that sets vaccine policy—is holding a special session. One item on the agenda is the highly anticipated vote for the Covid vaccine. We’re expecting VAERS data to be misused to suggest 25 pediatric deaths were caused by the vaccine. Here are the facts👇

I am pretty sure I had COVID-19 earlier this month, but I tested negative (by RDT) on days 1 & 3 of infection. How do you satisfy your academic curiosities about what pathogen has infected you without spending tons of $$ on diagnostic tests?

I see news outlets reporting on falling ‘fertility rates,’ and I find this terminology non-intuitive… and potentially problematic. Falling fertility rates tell us about reductions in women’s birth rates, not reductions in women’s fertility! Let me explain:

A glimmer of good news amidst the chaos! On Monday, I successfully defended my PhD focused on infectious disease modeling. And yes, my thesis title is an acronym for my last name. With gratitude to the incredible friends and mentors who got me here… Dr. Casey Middleton, reporting for duty 🫡🦠

Dad from Kentucky: “We finally started feeding our baby raw milk and he has grown like crazy!” Me: “Oh. Aren’t you worried about bird flu?” KY Dad: “Well I know the farmer and I’ve met his cows.” Me: “….” Someone hire this man with his 🪄 diagnostic capabilities. He can detect H5N1 just by sight!

I’m getting tired of saying “this is so fucked up!” everyday.

In September in Geneva we applauded a major milestone in the effort to eradicate measles and rubella viruses from the face of the earth. Today an unvaccinated child has died of measles in the country where the vaccine was developed. This is not greatness.

It’s Saturday afternoon. You get a work email from someone claiming to be an auditor, but they don’t sign the email. Who is this from? Is it legit? They ask you to describe what you accomplished last week. What do you do? You do what those security trainings taught you. *Report as phishing*

Last week, I had the honor of receiving 2nd place at CU Boulder's 3MT competition. This competition challenges grad students to distill their thesis down into a 3 minute talk for a general audience. My talk focused on how viral kinetics and probability theory inform testing policies... in < 3 mins ⏰

One of our supporters shared this with us—people are getting creative tonight!

Continuing the recruitment trend! Our lab has 2 (!) open postdoc positions🥳 We're looking for creative and curious scientists to lead new projects: one on deep-sea biological rhythms and another on the evolution of biological communication🐚🦗🦋🐙🦉 If you know someone who'd be a good fit, please share!

Back in 2023 I went to a workshop on “complex network contagion” that was mostly about simulations of disease spread and some real-world data analysis. Yesterday Ted Cruz declared it was a “questionable project promoting DEI or advancing neo-Marxist class warfare propaganda.”

We have come to the point where the world's largest international health organization is doing a $1b GoFundMe. This is unfortunately entirely legit. Until we can use our votes, our voices and our wallets are the tools we must rely on.

Last night I found out that the NSF math postdoctoral fellowship I applied for is being deleted because it does not comply with Trump’s executive orders on DEI in the federal government. I’m going to answer some FAQs and share some thoughts about this ordeal in this thread 1/n

We need to be giving this more attention - measles outbreaks are rough on patients, taxing on response, and indicative of larger public health vulnerabilities. Measles outbreak expands in West Texas around county with low vaccination rate | CNN

TFW your citation rabbit hole lands you at one of the first examples of vaccine clinical trials 🤓 This trial gained approval for public use of a vaccine that was originally developed to protect troops against influenza A during WWII.

Women leave academia at higher rates than men at every career stage, and attrition is especially high among three groups: tenured faculty, women in non-STEM fields, and women employed at less prestigious institutions, a #ScienceAdvances analysis finds.

A thread🧵 on application systems for postdoc jobs in the UK (applies to my university, but I've seen others and they're similar). I have seen (too many times) good applicants who don't seem to understand how recruitment is done on our side - not their fault! it's a privilege! - so here's how
