I am a Professor of Biology at San Diego State University. I study how animals can regenerate the nervous system from stem cells using tiny flatworms called planarians.

Even as the anti-vax lobby erodes public trust, new evidence confirms that "immunizations against Covid-19, RSV, and influenza have shown consistent effectiveness & safety and are associated with a substantially reduced risk of hospitalization & severe disease"

Overdue congratulations to Mallory Cathell, who successfully defended her doctoral dissertation back in June!
Since then, she has been hard at work preparing a manuscript based on her thesis.

URGENT: FlyBase has lost practically all its funding overnight; even user fees are tied up in denied grant funding. 🤬🤯

My lab studies bacterial infections. We spend a lot of time looking at (or for) species-specific genetic and genomic databases for hosts and microbes. FlyBase is the best of all—there is literally no comparison. Its existence is under threat. Please donate.
