Tetsu is an incredible scientist, mentor, and all-around person—can't recommend this lab enough. So stoked to be neighbors and get projects rolling!
I’ll be starting a lab as an Assistant Professor at Cornell @cornellengineering.bsky.social in 2026!

We’ll combine synthetic biology and materials science to engineer microbes into living materials & therapies.

We're recruiting PhD students & postdocs - please get in touch!

My postdoc work is now on bioRxiv!

We combined engineered bacteria and hydrogels to create implantable living materials that safely confine bacteria while letting them sense disease and release drugs from within.

It feels insane to write at this particular moment in history, but I'm starting a lab next year.

To be able to stay sane (and inspired by @cbo.bsky.social and others), I'm writing about it. I'm beginning with a roadmap for #science in these troubled times:

"We must stand in support of science in the face of attacks and simultaneously admit that we've been doing it wrong. One thing is certain: The changes we make ourselves will be healthier than the ones our adversaries demand."

Full of brilliant, nuanced insights (as usual from @cbo.bsky.social )

This isn't my first or even second time at the rodeo. I dealt with Ronald Reagan & George Bush trying to kill my community by ignoring the AIDS epidemic. It happened again when I lived in South Africa with Thabo Mbeki. And we won twice. So: courage. We will beat them too. Stay focused. Get to work.

Very nice
Incredibly excited to share that our manuscript was just published in @nature.com ! What a way to start the new year! 🎉

Hey if anyone is considering backing up any datasets for some reason today, the Open Science Framework has free storage up to 5G/private repository, and up to 50G/public repository.

(The OSF is run by a 501c3 (Center for Open Science), so if you do this you might also consider making a donation.)

Building on the UShER tree of millions of SARS-CoV-2 genomes maintained by Angie Hinrichs, Hugh Haddox and Georg Angehrn (and others in @matsen.bsky.social lab and @jbloomlab.bsky.social) have looked into how the neutral mutation rate varies along the genome:

[1/N]

www.biorxiv.org/content/10.1...
The mutation rate of SARS-CoV-2 is highly variable between sites and is influenced by sequence context, genomic region, and RNA structure
RNA viruses like SARS-CoV-2 have a high mutation rate, which contributes to their rapid evolution. The rate of mutations depends on the mutation type (e.g., A→C, A→G, etc.) and can vary between sites ...

I hung out with @daniellebeckman.bsky.social where she told us about her experiences as a student in Brazil that shaped her current interests in viruses inside the human brain. I hope you enjoy! Please like and subscribe for more!

Really proud to share our preprint describing early adaptation of H5N1 to US dairy cattle, and showing how these mutations enhance the ability of the virus to infect other mammals, such as pigs and humans.

With @influenzal.bsky.social @vidhid.bsky.social @drclairesmith.bsky.social and many more!
Polymerase mutations underlie adaptation of H5N1 influenza virus to dairy cattle and other mammals.
In early 2024, an unprecedented outbreak of H5N1 high pathogenicity avian influenza was detected in dairy cattle in the USA. The epidemic remains uncontrolled, with spillbacks into poultry, wild birds...

I’ve updated SARSCoV2 RBD antibody-escape calculator w new deep mutational scanning data of Yunlong Cao & Fanchong Jian.

My interpretation: antigenic evolution currently constrained by pleiotropic effects of mutations on RBD-ACE2 affinity, RBD up-down position & antibody neutralization

A thread on NIH Reorganization and the Scientific Management Review Board (SMRB)

Disclosure: I was involved with the SMRB since its inception and have very strong feelings about how it was used, misused, and abandoned. My passion on these issues will undoubtably show through.

Main take-away so far from very interesting presser on #Marburg outbreak in Rwanda: Health minister Sabin Nsanzimana says all cases are linked to known infection chains. The outbreak is one major cluster with three branches.

I did exactly this 7 years ago and it was one of the best decisions of my life.

Four different intern positions available: #microbiology, synthetic biology ( #synbio), #biochemistry, #bioinformatics. Here's the info (but apps via LinkedIn will be disregarded!)

When Google's AlphaFold stormed CASP in 2018, I thought it sigmalled the start of the era of private, for-profit cutting-edge discoveries in biology.

Six years later, I think we might look back on it as an anomaly.
