Biological Science Lab Technician
Research Interests
As a technician in the laboratory of Dr. Milton Drott, I work on the fungal pathogen Fusarium graminearum, a causal agent of Fusarium Head Blight (FHB) of cereal crops such as wheat and barley. FHB is a devasting disease worldwide caused by the fungus infecting flowering heads, resulting in yield loss not only from damaged kernels, but also due to mycotoxin contamination of the grain with trichothecene mycotoxins, including deoxynivalenol. Research in the Drott Lab includes studies of F. graminearum populations and genomes, the role of wild grasses in F. graminearum populations/ disease capabilities, and functional genomics of secondary metabolites. While I work on aspects of many of the Drott lab projects, I am most interested in functional genomics with regards to coordination of primary and secondary metabolism, and factors influencing population dynamics of F. graminearum and other Fusarium species that cause FHB.
