Current Graduate Advisees
Allison OakesGraduate Research Topic
American elm transformations for Dutch Elm disease resistance and phytoremediation.
Kristen StewartPersonal Statement
I have just recently joined the Chestnut Group after living 26 years in Florida. My goal is to graduate with the background and experience necessary to gain a career in the area of plant biotechnology, with a focus in genetic engineering.
Graduate Research Topic
I am presently focused on the effects of light intensity and spectral quality on growth and shoot initiation.
