Meet #MSKPostdoc Brendan Camellato from the @choijunhong.bsky.social Lab. Brendan is developing tools for “molecular recording”, giving cells the ability to capture the key events that shape both healthy development and the progression of diseases like cancer. #NPAW2026 🇨🇦
#BestPartOfScience: Constantly learning how the 
world works and contributing, even in small ways, 
to our shared understanding. Basic science may 
not directly cure disease, but it lays the
foundation for every biomedical breakthrough.

#BecomingAScientist: I was fascinated by both how much we know about life at the cellular and molecular level and how much remains to be discovered. That curiosity led me to a career in science.

#CareerAdvice: Science is a creative pursuit. 
Make time to step away from the bench and let 
your mind wander. Some of the best ideas emerge 
when you're not actively searching for them.

#FunFact: Playing drums helps me to think 
creatively, and to think in the moment, 
improvising when needed while always looking 
a little bit ahead at what’s coming next.

Everything you wanted to know about single-molecule epigenomics but were too afraid to ask! Wonderful to co-write (h/t ENORMOUS lift by @arnaudkr.bsky.social) this primer on our nascent field. Also, a 💯 example of wonderful colleagues building something *together*, not in competition =)

Maybe it’s time to say goodbye to UMAP and other low-dimensional embeddings (at least in many single-cell analyses). We developed MILK to encode single-cell populations into tree representations at unprecedented scales. www.biorxiv.org/content/10.6... Here’s what MILK is: 🧵

Trying a slightly new model (for us at least) of #openscience. With @ronanchaligne.bsky.social and @karolisk.bsky.social, we pitted 10x Genomics Chromium GEM-X against Illumina PIPseq V head-to-head to understand these two platforms for single-cell genomics. Some thoughts off the bleeding edge: /1
