Graduate Research Assistant

Sophia Holtz

Sophia is a Graduate Research Assistant in the Haus Lab who is currently working towards her Master’s in Horticulture. Her thesis research examines relationships between root morphology and Fusarium Root Rot resistance in dry beans. Additional projects she is working on include testing wild bean accessions for resistance to several Fusarium spp. isolates, and establishing a baseline curve for estimation of root system size via electrical capacitance. In her free time, Sophia enjoys spending time with her dog, skateboarding, and making art.
