We previously built programmable RNA sensors based on editing by housekeeping ADAR enzymes. But they can't sense arbitrary sequences due to design constraints (analogous to PAM for CRISPR). With our new "modulADAR", we overcome that constraint by leveraging ADAR's modularity.
Have you ever wondered what it would've been like to live in a different kind of society? After a record number of rejections, I'm self-archiving my first attempt at... flash fiction, featuring "Hemingway-esque economy" and "Ishiguro's measured revelation" (if you ask Claude).

Having often dealt with the frustration of binder-limited projects, we sought a more accessible source for nanobodies than yeast display or llama. Here we introduce Germinal, computationally designing antibody-like binders with such a hit rate that only tens need to be screened for each target.

Grateful for the recognition and for my team's dedication. When I wrote it in Oct, I didn't anticipate that the title would feel defiant. The original draft even had a now quaint reference to "the comparative comfort of the ivory tower", which was wisely removed.

So we beat on. Gene/cell therapies would benefit many patients, but often use proteins that could be recognized as non-self by our immune system and cause problems. We combine algorithms to build proteins that are therapeutically relevant and can masquerade as our own parts doi.org/10.1101/2025...

Super excited to finally share PANCS-Binders: our group's decade-long quest to accelerate protein binder discovery.

TLDR: PANCS-binders is fast (2 days), cheap (pennies), has extremely high fidelity (low false positive and negatives), and high-throughput.
