Arne Rietsch
Principal Investigator
arne.rietsch [at] case.edu

Arne has been studying P. aeruginosa for more than 15 years now (oh my). His primary interest is understanding how the type III secretion system is brought to bear on host cells, and how it's function, as well as the effector proteins delivered by this molecular syringe shape P. aeruginosa infections.

Emma Kundracik
postdoc

Emma was a MSTP student in the lab where she completed her thesis studying translocon function. She was apparently undeterred by the experience and and rejoined for a one-year, joint postdoc with the Yu lab after finishing her medical degree. Emma is trying to use structural approaches to study how Clew-1 interacts with Psl.

Lauren Siffert
Research technician

Lauren recently joined the lab and is examining the host range of Clew-1 and other biofilm-tropic bacteriophage.

Nicholas Porter
undergraduate

Nicholas is comparing Squantini and Clew-1 a finding surprising differences between the two (vague, I know!)

Arshia Joshi
