I study how microbial endophytes, fungi and bacteria that live inside plants, affect the performance, interactions with herbivores, and medicinal properties of the host plant. For my dissertation, I explored how endophyte species and infection frequencies vary geographically, in their alkaloidal genetic profiles, and in alkaloid production in two natural grasses, Poa alsodes andAchnatherum robustum. In experimental manipulations, I tested if these endophytes enhance anti-herbivore protection and plant growth. As a postdoc, I am continuing my work on plant endophytes at Dr. Stanley Faeth’s lab, and also I am studying oviposition site attraction of the Phlebotomus sand flies in Dr. Gideon Wasserberg’s lab.
