New NSF grant on predation funds the lab until 2027!

Posted on August 18, 2023 by cjsph

The QS Lab was recently awared a full-term grant by the NSF to exploring microbial predation. Our charismatic focal organism Dictyostelium discoideum is a super-generalist predator, readily eating the majority of bacteria it is encounters in nature. We’ll be investigating … Continue reading →
