Billy is interested in how the somatic nurse cells of the anther, the tapetum, support the development of the male germline.
He is using transcriptomics, at both a bulk and single-cell level, to explore novel regulators of tapetal development and their expression through developmental time.
He uses an array of imaging and genetic techniques to assay the effect of tapetum-expressed genes on the development of the male germline.
This work will give us a greater understanding of germline development, which ultimately underpins reproduction and the development of seeds.
