I discover novel genes for improving strawberry flavor and disease resistance. I make crosses between strawberry cultivars with different flavors, and generate complete volatile metabolomes for hundreds of fruit. I compare this data with subgenomic SNP-based genotyping (in an auto-allooctoploid!) to find QTL for important flavor and aromas. I use RNAseq to help find causal mutations in two ways: 1) Identifying SNPs within genes in my QTL region, and 2) Identifying co-locating eQTL markers.
Besides flavors, I do whole fruit transcriptome eQTL analysis and test candidate gene function via RNAi. I'm also in the middle of a cutting-edge R-gene sequencing project, using octoploid gDNA and RNA libraries enriched using in-house designed R-gene capture probes and sequences with Pacbio-SMRT.
My four-year GE industry experience (Simplot Plant Sciences) has given me an unusual perspective for a PhD student. The high cultural barriers-to-entry for GE crops discourages many truly valuable projects. In these turbulent times, the scientific community has to accept public outreach as civic and professional duty. I spend a lot of time doing public science communication, including co-founded the AmpliComm science communication effort with Plantae.org.
