Research Interests

Our lab studies molecular biology, ecology, and evolutionary biology questions related to bioluminescence in Photorhabdus luminescensP. luminescens are the only bioluminescent, soil-dwelling bacteria characterized to date; molecular evidence suggests that the genes responsible for light production in P. luminescens are related to similar genes in distantly-related, marine bacteria.

We also study aspects of the interesting life history of P. luminescens.  P. luminescens are a symbiotic partner of soil-dwelling nematodes.  In this symbiotic relationship, P. luminescens are able to help their nematode host kill insect larvae and other (competing) bacteria.  We are interested in small molecule-mediated interactions facilitated by P. luminescens with host nematodes, insect larvae, and other bacteria.
