I'm a HHMI Research Associate currently working on the functional characterization of genes that control the response to photoperiod in wheat using genetics and molecular biology tools, such as mutagenesis, transgenesis, epistatic interaction studies, gene expression analysis, and detailed phenotypic evaluations. For my PhD dissertation, I carried out the positional cloning of a wheat gene that controls heading time and increases the number of spikelets and grains per spike, two major yield components. After identifying the causal gene, I was able to transfer the favorable alleles from einkorn wheat into commercially relevant pasta and bread wheat varieties from the UC Davis and CIMMYT breeding programs and test its effects in field trials. As a postdoctoral scholar, I continued working on the molecular dissection of spike yield components in wheat, studying and deploying genes that modulate grain size, grain number, and biomass accumulation.
