Associate Professor of Biology

Rebecca Lamason investigates what happens when cellular functions are hijacked by unwanted interlopers: namely, the bacteria that engender diseases like spotted fever and meningitis.

Research Summary

In the Lamason lab, we investigate how intracellular bacterial pathogens hijack host cell processes to promote infection. In particular, we study how Rickettsia parkeri and Listeria monocytogenes move through our tissues via a process called cell-to-cell spread. We utilize cellular, molecular, genetic, biochemical and biophysical approaches to elucidate the mechanisms of spread in order to reveal key aspects of pathogenesis and host cell biology.
