What a question and a grand request,
To muse on why scientists should travel for a pest!
Forget lonely lab benches and the pipette's cold song,
There are better pursuits for which researchers long.

First 🟦 post - my main postdoc work is out in the world! We designed a Cas12a-based genetic screen to identify host factors that contribute to infection by the tickborne pathogen Rickettsia parkeri, and stumbled across a really exciting direct interaction between host and bacterium🦠. Check it out!
