I studied ruminant nutrition with animal (cattle), tissue explant, and cell models, focusing on the RNA, protein, and metabolites affected by the nutrients. With the RT-qPCR, western blot, metabolomics, lipidomics, RNA-seq, 16S sequencing, ELISA, histology, and other techniques, I studied more about the physiology of the gastrointestinal tract and how can it be affected by nutrition. I feel very excited to explore the unknown of ruminant nutrition.
