Research Focus:
Kristin’s PhD work focused on the transcriptional profiling in pig pre-implantation embryos and extraembryonic membranes and using histone deacetylase inhibitors such as Scriptaid and SAHA to improve cloning efficiencies. Kristin is now heavily focused on research efforts on using gene editing tools such as CRISPR/Cas9 to create disease resistant swine models.
